Citalopram hydrobromide is a highly selective and potent serotonin 
(5-hydroxytryptamine 5-HT) reuptake inhibitor with minimal effects on the 
neuronal reuptake of norepinephrine (NE) and dopamine (DA). The ability 
of citalopram to potentiate serotonergic activity in the central nervous 
system via inhibition of the neuronal reuptake of serotonin is thought to be 
responsible for its antidepressant action. Tolerance to the inhibition of serotonin reuptake is not induced by long term (14 days) treatment of rats with citalopram.

Citalopram has no or very low affinity for a series of receptors including serotonin 5-HT1A, 5-HT2, dopamine D1, and D2, a1-, a2-, b-adrenergic, histamine H1, muscarinic cholinergic, benzodiazepine, gamma aminobutyric acid (GABA) and opioid receptors.

 


Pharmacokinetics

Absorption
Following the administration of a single oral dose of citalopram (40 mg) to healthy male volunteers, peak blood levels occurred at about 4 hours (range 1 to 6 hours). The absolute bioavailability of citalopram was about 80% (range 52 to 93%) relative to an intravenous dose. Absorption was not affected by food.

Distribution
After intravenous infusion in healthy male volunteers the apparent volume of distribution (Vd)b was about 12 L/kg (range 9-17 L/kg), indicating a pronounced tissue distribution: (Vd)b oral was about 17 L/kg (range 14-17 L/kg). The binding of citalopram and its demethylated metabolites to human plasma proteins is about 80%.

Steady-state
The single- and multiple dose pharmacokinetics of citalopram are linear and dose proportional in a dose range of 10 to 60 mg/day. Steady-state plasma levels are achieved in patients in 1-2 weeks. At a daily dose of 40 mg, the average plasma concentration is about 83 ng/mL (n=114) with a range from 30 to 200 ng/mL. Citalopram does not accumulate during long term treatment. A clear relationship between citalopram plasma levels and therapeutic response or side effects has not been established.

Metabolism
Citalopram is metabolized in the liver to demethylcitalopram (DCT), didemethylcitalopram (DDCT), citalopram N-oxide and a deaninated propionic acid derivative. In vitro studies show that DCT, DDCT and citalopram-N-oxide also inhibit the neuronal reuptake of serotonin but are less selective and less potent than the parent compound and are of minor clinical importance. Unchanged citalopram is the predominant compound in plasma. In vitro studies indicated that the biotransformation of citalopram to its demethyl metabolites depends on both CYP2C19 and CYP3A4, with a small contribution from CYP2D6.

Elimination
The elimination half life of citalopram (t1/2b) is approximately 37 hours (range 30-42 hours) which allows recommendation of once-daily dosing. The systemic citalopram plasma clearance (Cl5) is 0.33 L/min. Citalopram is eliminated primarily via the liver (85%) and the remainder via the kidneys; approximately 12% (range 6-21%) of the daily dose is excreted in urine as unchanged citalopram.

Special Populations:   Back to top of page

Elderly Patients
Elderly patients (4 males and 7 females aged 73-90 years), received a 20 mg/day dose of citalopram for 3-4 weeks. In the elderly, steady state plasma levels were elevated (106 ng/mL), half-life prolonged (1.5-3.75 days) and clearance decreased (0.08-0.3 L/min). Elevation of citalopram plasma levels occurred at an earlier age in females than in males, In this population, lower doses and a lower maximum dose of citalopram are recommended.

Reduced Hepatic Function
The pharmacokinetics of citalopram were compared in patients with reduced hepatic function (3 female and 6 male patients aged 41-60 years) to those seen in 12 healthy male volunteers (aged 21-43 years), In patients with reduced hepatic function the half-life of citalopram was approximately doubled (83 hours versus 37 hours), steady state citalopram concentrations increased by 61% and oral clearance decreased by 37%. Consequently the use of citalopram in patients with reduced hepatic function should be approached with caution and lower maximal doses should be prescribed (see PRECAUTIONS and DOSAGE AND ADMINISTRATION).

Reduced Renal Function
In patients with mild to moderate reduction of the renal function (4 females and 3 males, aged 30-55 years), citalopram was being eliminated more slowly than in 12 healthy male volunteers (aged 21-43 years), half-lives being 49 hours versus 37 hours. However, mild to moderate renal impairment had no major influence on the kinetics of citalopram. At present, no information is available for chronic treatment of patients with severely reduced renal function (creatinine clearance <20 mL/min). 


Indications and Clinical Use   Back to top of page

Citalopram hydrobromide is indicated for the symptomatic relief of depressive illness.

The relapse rate was significantly lower in citalopram-treated patients than in placebo-treated patients in two placebo-controlled studies, that were conducted over a 24-week period in patients who responded to 6 or 8 weeks of acute treatment with citalopram (see CLINICAL TRIALS under ACTION AND CLINICAL PHARMACOLOGY.) Nevertheless, the physician who elects to use citalopram for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.


Contraindications   Back to top of page

Citalopram hydrobromide is contraindicated in patients with known hypersensitivity to citalopram hydrobromide or the excipients of the drug product.

Monoamine Oxidase Inhibitors
In patients, receiving selective serotonin reuptake inhibitors (SSRIs) in combination with a monoamine oxidase inhibitor (MAOI), there have been reports of serious, sometimes fatal, reactions including hyperthermia, rigidity, myoclonus, autonomic instability with possible rapid fluctuations of vital signs, and mental status changes, including extreme agitation progressing to delirium and coma. These reactions have also been reported in patients who have recently discontinued SSRI treatment and have been started on a MAOI. Some cases presented with features resembling serotonin syndrome. Therefore, it is recommended that citalopram should not be used in combination with a MAOI or within 14 days of discontinuing treatment with a MAOI. Similarly, at least 14 days should elapse after discontinuing citalopram treatment before starting a MAOI.


Precautions   Back to top of page

Suicide
The possibility of a suicide attempt is inherent in depression and may persist until remission occurs. Therefore, high risk patients should be closely supervised throughout therapy with Citalopram hydrobromide and consideration should be given to the possible need for hospitalization. In order to minimize the opportunity for overdosage, prescription for citalopram should be written for the smallest quantity of drug consistent with good patient management.

Activation of Mania/Hypomania
In placebo-controlled trials with citalopram, some of which included patients with bipolar disorder, mania/hypomania was reported in 0.1% of 1027 patents treated with citalopram versus none of the 426 patients treated with placebo. Activation of mania/hypomania has also been reported in a small proportion of patients with major affective disorders treated with other marketed antidepressants. If a patient enters a manic phase, citalopram should be discontinued.

Seizures
Citalopram has not been systematically evaluated in patients with a seizure disorder. These patients were excluded from clinical studies during the premarketing testing of citalopram. In clinical trials, seizures occurred in 0.25% of patients treated with citalopram and in 0.23% patients treated with placebo. Like other antidepressants, citalopram should be used with caution in patients with a history of seizure disorder.

Serotonin Syndrome
Rarely, the occurrence of serotonin syndrome has been reported in patients receiving SSRIs. A combination of symptoms, possibly including agitation, confusion, tremor, myoclonus and hyperthermia, may indicate the development of this condition.

5-HT1 Agonists
There have been rare postmarketing reports describing patients with weakness, hyperreflexia and incoordination, following the concomitant use of a SSRI and the antimigraine drug sumatriptan, a 5-HT1 agonist. Such interaction should be considered if citalopram is to be used in combination with a 5-HT1 agonist.

Hyponatremia
Hyponatremia and SIADH (syndrome of inappropriate antidiuretic hormone secretion) have been reported with citalopram use as a rare adverse event.

Pregnancy and Nursing Mothers
The safety of citalopram during pregnancy and lactation has not been established. Therefore, citalopram should not be used during pregnancy, unless, in the opinion of the physician, the expected benefits to the patient markedly outweigh the possible hazards to the fetus. Citalopram is excreted in human milk. Citalopram should not be administered to nursing mothers unless, in the opinion of the treating physician, the expected benefits to the patient markedly outweigh the possible hazards to the child.

Pediatric Use
Safety and effectiveness in patients below the age of 18 have not been established.

Geriatric Use
In premarketing clinical trials, 800 elderly patients (>=65 years of age) have been treated with citalopram. Of these patients 298 were >=75 years old. In a pharmacokinetic study (n=11, age 73 to 90 years), clearance was substantially decreased and half-life prolonged (see PHARMACOKINETICS). In a 6-week placebo-controlled study, approximately equal numbers of patients received citalopram at 20 or 30 mg per day, as the final dose. In about 5% of patients, the final dose was 10 mg per day (see CLINICAL TRIALS). Consequently, elderly patients should be administered lower doses and a lower maximum dose.

Hepatic Impairment
Citalopram clearance was significantly decreased and plasma concentrations, as well as elimination half-life significantly increased (see PHARMACOKINETICS). Consequently, the use of citalopram in hepatically impaired patients should be approached with caution and a lower maximum dosage is recommended.

Renal Impairment
No dosage adjustment is needed in patients with mild to moderate renal impairment. To date, no information is available on the pharmacokinetic or pharmacodynamic effects of citalopram in patients with severely reduced renal function (creatinine clearance <20 mL/min).

Use in Patients with Cardiac Disease
Citalopram has not been systematically evaluated in patients with a recent history of myocardial infarction or unstable heart disease. Patients with these diagnoses were generally excluded from clinical trials during the drugs premarketing assessment. However, the electrocardiograms of patients, who received citalopram in clinical trials, indicate that citalopram was not associated with the development of clinically significant ECG abnormalities.

In clinical trials, citalopram caused small but statistically significant decreases in heart rate (see ECG under ADVERSE REACTIONS) Consequently, caution should be observed when citalopram is initiated in patients with pre-existing slow heart rate.

Use in Diabetic Patients
Citalopram has not been systematically evaluated in diabetic patients since diabetes constituted an exclusion criterion. Although 13 patients did receive insulin during the studies, this number is too small to determine whether citalopram affects the response to insulin. Rare events of hypoglycemia were reported. Citalopram should be used with caution in diabetic patients on insulin or other antidiabetic drugs.

Interference with Cognitive and Motor Performance
In studies in normal volunteers, citalopram in doses of 40 mg/day did not impair cognitive function or psychomotor performance. However, psychotropic medications may impair judgement, thinking or motor skills. Consequently, patients should be cautioned against driving a car or operating hazardous machinery until they are reasonably certain that citalopram does not affect them adversely.

Electroconvulsive Therapy (ECT)
The safety and efficacy of the concurrent use of citalopram and ECT have not been studied.


Abrupt Discontinuation   Back to top of page

After 8 weeks of treatment with citalopram, abrupt discontinuation of treatment caused a higher incidence of anxiety, emotional indifference, impaired concentration, headache, migraine, paresthesia, and tremor than was seen in patients who continued on citalopram. These symptoms are not indicative of addiction.

Although it is not known whether gradual discontinuation will prevent the discontinuation symptoms, it is recommended that the dosage of citalopram should be tapered off over 1 to 2 weeks.

Adverse Findings Observed in Short-Term, Placebo-Controlled Trials

Adverse Reactions Associated with Discontinuation of Treatment
From the short-term (4 to 6 weeks) placebo-controlled, Phase III clinical trials, 15.9% (163/1027) of the citalopram-treated patients discontinued treatment due to an adverse event. The discontinuation rate in the placebo-treated patients was 7.7% (33/426).

The events associated with discontinuation of citalopram in 1% or more of patients at a rate of at least twice that of placebo, were as follows: Nausea (4.1% versus 0.0%), insomnia (2.4% versus 12%), somnolence (2.4% versus 1.2%), dizziness (2.3% versus 0.7%), vomiting (1.3% versus 0.0%), agitation (1.2% versus 0.0%), asthenia (11% versus 0.5%), and dry mouth (1.1% versus 0.2%).

Incidence of Adverse Events in Placebo-controlled Studies
Table 1 enumerates the incidence of treatment-emergent adverse events that occurred in 1027 depressed patients who received citalopram at doses ranging from 10 to 80 mg/day in placebo-controlled trials of up to 6 weeks in duration. Events included are those occurring in 2% or more of patients treated with citalopram, and for which the incidence in patients treated with citalopram was greater than the incidence in placebo-treated patients. Reported adverse events were classified using the standard World Health Organization (WHO)-based dictionary terminology.

The prescriber should be aware that these figures cannot be used to predict the incidence of adverse events in the course of usual medical practice where patient characteristics and other factors differ from those which prevailed in the clinical trials. Similarly, the cited frequencies cannot be compared with figures obtained from other clinical investigations involving different treatments, uses, and investigators. The cited figures, however, do provide the prescribing physician with some basis for estimating the relative contribution of drug and non-drug favors to the adverse event incidence rate in the population studied.

The following events had an incidence on placebo >= citalopram: asthenia, back pain, headache, dizziness, constipation, palpitation, insomnia, abnormal vision.

Most Frequent Adverse Events
Adverse events that occurred in citalopram-treated patients in the course of the short-term, placebo-controlled trials with an incidence greater than or equal to, 10% were: nausea, dry mouth, somnolence, and increased sweating (Table 1).

Dose Dependency of Adverse Events
The potential relationship between the dose of citalopram and the incidence of an adverse event was examined in a fixed dose short-term, placebo-controlled study in which patients received citalopram at doses of 10, 20, 40 or 60 mg per day. The incidence of insomnia, increased sweating, and fatigue was dose-related.

Male and Female Sexual Dysfunction with SSRIs
While sexual dysfunction is often part of depression and other psychiatric disorders, there is increasing evidence that treatment with selective serotonin reuptake inhibitors (SSRIs) may induce sexual side effects. This is a difficult area to study because patients may not spontaneously report symptoms of this nature, and therefore, it is thought that sexual side effects with SSRIs may be underestimated.

In placebo-controlled, short-term clinical trials, the reported incidence of decreased libido, ejaculation disorders (primarily ejaculation delay and ejaculation failure), and impotence in male depressed patients receiving citalopram (n=404) was 3.7%, 6.2%, and 3.2%, respectively. In female depressed patients receiving citalopram (n=623), the reported incidence of decreased libido and anorgasmia was 1.3% and 1.1%, respectively. The reported incidence of each of these adverse events was <=1% among male and female depressed patients receiving placebo.

Weight Changes
Patients treated with citalopram in controlled trials experienced a weight loss of about 0.5 kg compared to no change for placebo patients.

ECG
Retrospective analyses of electrocardiograms in citalopram-treated (n=779 <60 years and n=313 >=60 years) and placebo-treated (n=74 <60 years and n=43 >=60 years) patients indicated that citalopram decreases heart rate. In patients <60 years old, the mean decrease was approximately 5 bpm, while in patients >=60 years old, mean decreases ranged between 5 to 10 bpm. Following the initial drop, heart rate remained decreased but stable over prolonged periods of time (up to one year in over 100 younger and over 50 elderly patients). The effect was reversible within approximately a week after stopping treatment.

In the 6-week, fixed dose, dose-response study, the mean decreases in heart rate ranged between 2-6 bpm in the 20-60 mg/day dose range, but the effect did not seem to be dose-related and was independent of gender. In placebo-treated patients heart rates remained unaffected. The differences in heart rates between citalopram and placebo-treated patients were statistically significant. ECG parameters, including QT interval, remained unaffected.

Clinical Trials   

The efficacy of citalopram in the treatment of depression was established in five placebo-controlled studies in patients who met the DSM III or DSM-III-R criteria for major depression. Response to treatment was evaluated by the Hamilton Depression Rating Scale (HAMD) and/or the Montgomery Asberg Depression Rating Scale (MADRS) as well as the Clinical Global Impression (CGI) Severity Scale. On the HAMD and MADRS, total scores, selected single items, and percentage of responders (defined as patients whose HAMD/MADRS total score decreased by at least 50% versus baseline) were assessed.

In a 6-week fixed dose, dose-response study, patients received citalopram at doses of 10, 20, 40, or 60 mg/day or placebo (n=129 to 131 per group). The 40 and 60 mg day doses were titrated, with patients reaching these designated doses within 4 and 8 days, respectively. The study showed that the 40 and 60 mg/day doses were significantly more effective than placebo, although the 60 mg/day dose was not more effective than the 40 mg/day dose. The lower doses did not show statistically significant superiority over placebo, except on the MADRS: on this scale the percent of responders was significantly higher in all the citalopram-treated groups than in the placebo-treated group.

The second study was a 4-week flexible dose study in which 85% of the depressed patients met the criteria for melancholia. At entry, 89 and 91 patients were randomized to the citalopram and placebo groups, respectively. This was the only study in which more male than female patients participated (64% versus 36%). The initial dose of citalopram, 20 mg/day, could be titrated to the maximal tolerated dose or a maximum dose of 80 mg/day. Patients treated with citalopram showed significantly greater improvement than patients treated with placebo. At week 4, the average daily dose was 63 mg, with 52% of patients receiving the 80 mg/day dose.

In a 6-week fixed-dose study, patients received citalopram, 20 or 40 mg/day, or placebo (n=64 to 70 per group). Patients treated with citalopram 40 mg/day, showed significantly greater improvement than placebo-treated patients. The difference between the lower dose of citalopram and placebo was not significant. In another 6-week fixed-dose study, patients received citalopram 20 or 40 mg/day or placebo (n=88 to 97 per group). Although citalopram-treated patients improved to a somewhat greater degree than the placebo-treated patients, the differences between drug and control groups did not reach statistical significance due to a high placebo response, i.e. substantial improvement in the placebo group.

A 6-week, flexible dose study was conducted in elderly, depressed patients (the mean age of male and female patients was 75 and 77 years, respectively) to determine the antidepressant effect and safety of citalopram in this subpopulation. The number of patients who received citalopram and placebo was 98 and 51, respectively. The study allowed patients to enter with lower baseline HAMD scores than are usually acceptable (>=18 in clinical trials). However, only a small percentage of patients had HAMD scores of less than 18 at entry. The dose of citalopram was titrated from a starting dose of 10 mg day to a maximum dose of 30 mg day. Patients treated with citalopram showed significantly greater improvement than patients treated with placebo. The final dose of citalopram was 10, 20 and 30 mg/day in 5%, 51% and 44% of patients, respectively.

The effectiveness of citalopram in preventing relapse was assessed in two long-term studies. Depressed patients who responded to citalopram during an initial 6 or 8 weeks of acute treatment (fixed doses of 20 or 40 mg/day in one study and flexible doses of 20-60 mg/day in the second study) were randomized to continue on citalopram or receive placebo. The number of patients who received citalopram and placebo was 257 and 116, respectively. In both studies, patients who continued on citalopram experienced significantly lower relapse rates over the subsequent 6 months compared to those receiving placebo. In the fixed-dose study, the relapse rates were similar at the 20 and 40 mg/day doses, namely 10% and 12%, respectively. Of the placebo-treated patients, 31% experienced relapse. In the flexible-dose study, the relapse rates were 14% and 24% in the citalopram- and placebo-treated patients, respectively. While the majority of patients (76%) were maintained on 20 or 40 mg/day of citalopram during most of the study, some patients received 60 mg/day, while a few patients were maintained on less than 20 mg/day.

Drug Interactions:   Back to top of page

Monoamine Oxidase Inhibitors (MAOI)
For interactions between citalopram and MAOI, see CONTRAINDICATIONS.

General
The studies described in this section were carried out in young, healthy, mostly male volunteers. In addition, some of the studies, namely interactions with metoprolol, warfarin, digoxin, imipramine, and levomepromazine, utilized only single doses of these drugs, although citalopram was given repeatedly to attain steady state. Thus, data are not available in patients who would be receiving these drugs on an ongoing basis at therapeutic doses.

Metoprolol
Coadministration of citalopram (40 mg/day for 22 days) and the b-adrenergic backing agent metoprolol (single dose of 150 mg), resulted in a two-fold increase in the plasma levels of metoprolol. However, the effect of metoprolol on blood pressure and heart rate was not affected.

Warfarin
Administration of citalopram (40 mg day for 21 days), did not affect either the pharmacokinetics or the pharmacodynamics (prothrombin time) of a single, 1 mg dose of warfarin.

Digoxin
Administration of citalopram (40 mg/day for 21 days) did not affect the pharmacokinetics of digoxin (single dose of 1 mg), although the serum levels of citalopram were slightly lower in the presence of digoxin.

Imipramine
Coadministnation of citalopram (40 mg/day for 10 days) and the tricyclic antidepressant, imipramine (single dose of 100 mg), did not affect the pharmacokinetics of either drug. However, in the presence of citalopram, the concentration of desipramine, the metabolite of imipramine, increased by approximately 50% and its half-life was prolonged. The results indicate that citalopram does not interfere with the demethylation of imipramine to desipramine but does inhibit the metabolism of desipramine to its 2-hydroxy metabolite. Consequently, concomitant treatment with citalopram and imipramine/ desipramine should be undertaken with caution.

Levomepromazme
Coadministration of citalopram (40 mg/day for 10 days) and levomepromazine (single dose of 50 mg), did not affect the pharmacokinetics of either drug.

Lithium
Coadministration of citalopram (40 mg/day for 10 days) and lithium (30 mmol/day for 5 days), did not affect the pharmacokinetics of either drug. However, since lithium may increase serotonergic neurotransmission, concomitant treatment with these two drugs should be undertaken with caution.

Cimetidine
Citalopram 40 mg/day was administered for 29 days. During the last 8 days of treatment, cimetidine (400 mg bid) was added to the treatment regimen. In the presence of cimetidine, a potent inhibitor of hepatic cytochrome P450 enzymes, the Cmax and AUC of citalopram was increased by 39% and 41%, respectively. Thus, caution should be exercised at the upper end of the dose range of citalopram when it is used concomitantly with high doses of cimetidine.

Carbamazepine
Carbamazepine, titrated to 400 mg day, was given for 21 days alone and then in combination with citalopram (40 mg day) for an additional 14 days, citalopram did not affect the plasma levels of either carbamazepine, a CYP3A4 substrate, or its metabolite, carbamazepine-epoxide, However, since carbamazepine is a microsomal enzyme inducer, the possibility that carbamazepine may increase the clearance of citalopram should be considered if the two drugs are given concomitantly.

Cytochrome P450 Isozymes
Using in vitro models of human liver microsomes, the biotransformation of citalopram to its demethyl metabolites was shown to depend on both CYP2C19 and CYP3A4, with a small contribution from CYP2D6. Studies have also indicated that citalopram is a weak inhibitor of CYP2D6 and CYP2C19 and a weak or negligible inhibitor of CYP3A4 and CYP1A2. As data are not available from clinical pharmacokinetic studies, the possibility that the clearance of citalopram will be decreased when citalopram is administered with a potent inhibitor of CYP3A4 (e.g., ketoconazole, itraconazole, fluconazole or erythromycin), or a potent inhibitor of CYP2C19 (e.g., omeprazole), should be considered.

Alcohol
Although citalopram did not potentiate the cognitive and psychomotor effects of alcohol in volunteers, the concomitant use of alcohol and citalopram should be avoided.

Other Drugs
In clinical trials, citalopram has been given concomitantly with benzodiazepines (anxiolytics/hypnotics), analgesics (NSAIDs, nonNSAIDs), lithium, antihistamines, antihyperensives or other cardiovascular drugs.

Symptoms and Treatment of Overdosage Back to top of page

Citalopram hydrobromide has a wide margin of safety in overdose. Cases of overdoses involved the ingestion of citalopram either alone or in combination with other drugs and/or alcohol. In clinical trials, with overdoses of citalopram ranging from 180 mg to 2000 mg, all patients recovered. One patient, ingesting over 1500 mg citalopram, had reversible ECG abnormalities, the most important of which was prolongation of QTc.

Of the cases reported postmarketing, six were fatal. The doses of citalopram in these patients ranged from 840 mg to 1960 mg. All but one of these patients had concomitant drugs and/or alcohol. Serum levels of citalopram in patients who ingested 2000 mg, 4000 mg and 5200 mg of the drug were 2900 ng/mL, 3800 ng/mL and 10,040 ng/mL citalopram, respectively. All these patients recovered. Three fatal cases of serotonin syndrome have been reported in patients who took overdoses of moclobemide (Manerix) and citalopram. The plasma concentrations of moclobemide were between 16 and 90 mg/L (therapeutic range: 1 to 3 mg/L) and those of citalopram between 0.3 and 1.7 mg (therapeutic concentration: 0.3 mg/L). This indicates that a relatively low dose of citalopram, given with an overdose of moclobemide represents a serious risk for the patient.

Symptoms most often accompanying citalopram overdose included dizziness, sweating, nausea, vomiting, tremor, and somnolence. In more rare cases, observed symptoms included confusion, loss of consciousness, convulsions, coma, sinus tachycardia, cyanosis, hyperventilation and rhabdomyolysis.


Management of Overdose  Back to top of page

Establish and maintain an airway to ensure adequate ventilation and oxygenation. Gastric lavage and use of activated charcoal should be considered. Cardiac and vital sign monitoring are recommended, along with general symptomatic and supportive measures. There are no specific antidotes for citalopram.

Due to the large volume of distribution of citalopram, forced diuresis, dialysis, hemoperfusion and exchange transfusion are unlikely to be of benefit. In managing overdosage, the possibility of multiple drug involvement must be considered.


Dosage and Administration   Back to top of page

General
Citalopram hydrobromide should be administered once daily, in the morning or evening, with or without food.

Adults
Citalopram should be administered as a single oral dose of 20 mg/day. In patients who do not respond adequately, an increase of dosage to 40 mg/day should be considered. Certain patients may require 60 mg/day. However, in a dose response study, the 60 mg/day dose did not demonstrate an advantage regarding effectiveness over the 40 mg/day dose. Dose increases should usually occur in increments of 20 mg, at intervals of no less than one week.

Elderly Patients
A single oral dose of 20 mg/day is the recommended dose for most elderly patients. Some patients may respond to a 10 mg/day dose (see CLINICAL TRIALS under ACTION AND CLINICAL PHARMACOLOGY). The dose may be titrated to a maximum of 40 mg/day if needed and tolerated.

Hepatic Impairment
Patients with reduced hepatic function should receive dosages of no more than 30 mg/day.

Renal Impairment
No dosage adjustment is necessary for patients with mild to moderate renal impairment. Since there is no information available on the pharmacokinetic or pharmacodynamic effects of citalopram in patients with severe renal impairment, citalopram should be used with caution in these patients.

Maintenance Treatment
Evaluation of citalopram in two placebo-controlled studies has shown that its antidepressant efficacy was maintained for periods of up to 24 weeks, following 6 or 8 weeks of initial treatment (total of 32 weeks) (See CLINICAL TRIALS under ACTION AND CLINICAL PHARMACOLOGY). In the flexible dose study, the great majority of patients were receiving 20 or 40 mg/day doses both at 12 and 24 weeks. During maintenance therapy the dosage should be kept at the lowest effective level and patients should be periodically reassessed to determine the need for continued treatment.

Back to top of page


Switching Patients to or from a Monoamine Oxidase Inhibitor (MAOI) 

At least 14 days should elapse between discontinuation of a MAOI and initiation of therapy with citalopram. Similarly, at least 14 days should be allowed after stopping citalopram before starting a MAOI (see CONTRAINDICATIONS).


Discontinuation of Citalopram Treatment   Back to top of page

Since some patients may experience discontinuation symptoms when citalopram is stopped abruptly, the dose of citalopram should be tapered off over 1 to 2 weeks.

What is Cymbalta?

Cymbalta is a new antidepressant manufactured by Eli Lilly and Company, the approval of which Has finally been granted by the U.S. Food and Drug Administration.  This happens on the heals of one suicide of a 19 year-old, in perfect health, no mental disorder, hanging herself at the Eli Lilly complex, after taking Cymbalta. This is approved when pressure is being put on all of the pharmaceutical firs to fully disclose their clinical trials.

Did the FDA feel a little pressure from the current Administration? If you have an adverse event or commit suicide while taking Cymbalta, odds are the current Administration will pay for and support Eli Lilly to beat you in court. The current administration admits this.

August 11, 2004 - The FDA states Cymbalta had nothing to do with the hanging death at the Eli Lilly facility. Let's look at the known data here:

  1. You have a healthy 19 year old female as part of the Cymbalta clinical trials.

  2. She is given a much higher dosage then recommended.

  3. Part of her trial was to quit the Cymbalta quickly

  4. She hangs herself

  5. She has no mental illness

  6. She was in perfect physical health per Eli Lilly

  7. She was in the trial to earn money for college

  8. The current administration will supply Eli Lilly with their attorneys to help fight consumer lawsuits because "the FDA is never wrong"

  9. The FDA uses their own lead attorney to help Eli Lilly and others fight consumer lawsuits because the FDA is never wrong.

  10. The current administration is full of Eli Lilly past executives.

  11. You would think if the FDA clears Cymbalta as the cause of death, they would disclose why or what the reason was.

  12. Amazing, the FDA statement of Cymbalta having nothing to do with this suicide, would come within 1 week of Cymbalta being approved by the FDA and within 3 weeks of the massive launch of Cymbalta by Eli Lilly. Eli Lilly will have more drug reps hit the streets to visit physicians then with any other drug of theirs in the past.

  13. If Cymbalta fails, Eli Lilly will suffer on Wall Street.

Eli Lilly is being sued again after a SWAT captain commits suicide after only 3 days of Prozac use. Eli Lilly has already settled 2 suits out of court for the same issue. Know what can happen before you take these medications. There is a way to know. Click here for story. (Opens new browser)

August 4, 2004 - Now that Cymbalta is approved by the FDA will Eli Lilly disclose all of their clinical trials? With a high profile suicide occurring during the clinical trial, will the pressure be enough on Eli Lilly? When a healthy volunteer, with no known mental illness or physical problem commits suicide on Cymbalta, will Eli Lilly disclose all of the facts?

Eli Lilly, I know you are on this Web Site daily, especially when it comes up first on most search engines for your new antidepressant Cymbalta, what are you going to do? Disclose all of the facts or not? If you work with Eli Lilly and feel it is time for you to come clean and disclose all you know about Cymbalta hidden information, Click here and send an e-mail.

What is Cymbalta?

Cymbalta is a brand-name for a drug called duloxetine.  It is in a class of drugs known as dual uptake inhibitors.   So what is a dual uptake inhibitor -- or an uptake inhibitor, for that matter?

The way a neurotransmitter works is, it is passed along from one nerve to another.  A bit of it is sent out at a time from one nerve to the next.  After a bit is sent out and received by the next nerve, any of the neurotransmitter remaining between the nerves is taken back by the first nerve, a process called reuptake. 

A reuptake inhibitor prevents this reuptake process from occurring, which means that, when Cymbalta is active, certain neurotransmitters are transmitted in steady streams from one nerve ending to the next, instead of being sent in bits periodically, which they normally are.  The neurotransmitters affected by Cymbalta are known as serotonin and norepinephrine.  And now we can explain what "dual uptake inhibitor" means -- it simply means a drug that affects the reuptake of two neurotransmitters instead of one.

Does Cymbalta cure depression?

Good question.  If depression has never been proven to be caused by neurotransmitters (or the lack of them), that question cannot obviously be answered conclusively. 

Apparently, Eli Lilly and Company knows this.  According to a recent news release from Eli Lilly regarding Cymbalta:   "Many experts believe treating the complete spectrum of depression symptoms is intrinsic to a lasting recovery. As well, combined action through two key neurotransmitters - serotonin and norepinephrine - may provide a more rapid and sustained clinical effect."

Note the subtle uncertainties in these statements, for there is absolutely no scientific proof behind them.  "Many experts believe treating the complete spectrum of depression symptoms..."   "...combined action through two key neurotransmitters - serotonin and norepinephrine - may provide..."

Translation:  They don't know how, why, or if their drug works.  This is evident in the numerous -- and serious -- side effects provided by other antidepressants.  Lilly's press release did not even address side effects, but another of their releases regarding Cymbalta's clinical trials revealed three of the exact same side effects as other antidepressants:  Dizziness, anxiety, and nausea. 

In that Cymbalta has the exact same action as Wyeth's drug Effexor, one could assume the same side effects.  (See "Precautions" section on Effexor page). (Opens new browser)

What is Depression?

Depression is defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association, this way: 

The essential feature of a Major Depressive Episode is a period of at least 2 weeks during which there is either depressed mood or the loss of interest or pleasure in nearly all activities.  In children and adolescents, the mood may be irritable rather than sad.  The individual must also experience at least four additional symptoms drawn from a list that includes major changes in appetite or weight, sleep, and psychomotor [of or relating to movement or muscular activity associated with mental processes] activity; decreased energy; feelings of worthlessness or guilt; difficulty thinking, concentrating, or making decisions; or recurrent thoughts of death or suicidal ideation, plans, or attempts."

While these elements can certainly be seen to exist and have been experienced by many, labeling "depression" as an illness has been criticized by many as simply labeling part of life itself as a physical "disease" which must be "cured". 

This could be debated endlessly, however, and whole long texts have been written on the subject.  Depression as a state of mind certainly does exist, and can be painful.  The question to be addressed here, though, is, does depression truly have a physical cause that can be addressed with medication?

For the answer, let's go back to the DSM.  The only information given there as to physical causes of depression is: 

Neurotransmitters implicated in the pathophysiology [study of the physical effects of a disease] of a Major Depressive Episode include norepinephrine, serotonin, acetylcholine
, dopamine, and gamma-aminobutryric acid.  Back to top of page

All right, what does all that mean?  Here's a simple explanation.  A neurotransmitter is a chemical that helps transmit nerve impulses through the nervous system.  There are many different neurotransmitters used by the body.  What the DSM definition is saying is that, by some method, the neurotransmitter chemicals known as  norepinephrine, serotonin, acetylcholine
, dopamine, and gamma-aminobutryric acid seemed to be lower in some depressed people, or higher in non-depressed people. 

Note carefully the use of the word implicated in the DSM definition, however.  And therein is the first clue, for it has never been clinically proven that depression is based in neurotransmitters.  We repeat:  Never.  And believe it or not, there is not a doctor on Earth that will disagree with that statement.

Which leads to the conclusion that a physical cause for depression has never been isolated.  Why, then, is Eli Lilly and Company, Cymbalta's manufacturer, so insistent that Cymbalta is a great treatment for depression?

For the answer to this, let's turn to Eli Lilly and find out exactly what Cymbalta is, and how it works.

Should You Take Cymbalta? Back to top of page

The answer is, of course, up to you.  Before you do, however, become fully informed of the dangers from the manufacturer.  As yet the full list of side effects have not been published. 

You should also be aware of a dangerous metabolism issue that may affect you, and for which you should be tested before you take such a drug. 

CYMBALTA

(duloxetine hydrochloride)

Pharmacokinetics

  CYMBALTA has an elimination half-life of about 12 hours (range 8 to 17 hours) and its pharmacokinetics are dose proportional over the therapeutic range. Steady-state plasma concentrations are typically achieved after 3 days of dosing. Elimination of CYMBALTA is mainly through hepatic metabolism involving two P450 isozymes, CYP2D6 and CYP1A2.

  Absorption and Distribution – Orally administered CYMBALTA is well absorbed. There is a median 2-hour lag until absorption begins (T lag), with maximal plasma concentrations C max) of CYMBALTA occurring 6 hours post dose. Food does not affect the Cmax of CYMBALTA, but delays the time to reach peak concentration from 6 to 10 hours and it marginally decreases the extent of absorption (AUC) by about 10%. There is a 3-hour delay in absorption and a one-third increase in apparent clearance of CYMBALTA after an evening dose as compared to a morning dose.

  The apparent volume of distribution averages about 1640 L. CYMBALTA is highly bound (>90%) to proteins in human plasma, binding primarily to albumin and ą1-acid glycoptrotein. Plasma protein binding of CYMBALTA is not affected by renal or hepatic impairment.

  Metabolism and Elimination – Biotransformation and disposition of CYMBALTA in humans have been determined following oral administration of 14C-labeled CYMBALTA. CYMBALTA comprises about 3% of the total radiolabeled material in the plasma, indication that it undergoes extensive metabolism to numerous metabolites. The major biotransformation pathways for CYMBALTA involve oxidation of the naphthyl ring followed by conjugation and further oxidation. Both CYP2D6 and CYP1A2 catalyze the oxidation of the naphthyl ring in vitro.   Metabolites found in plasma include 4 –hydroxy duloxetine glucuronide and 5-hydroxy, 6-methoxy duloxetine sulfate. Many additional metabolites have been identified in urine, some representing only minor pathways of elimination. Only trace (1% of the dose) amounts of unchanged CYMBALTA are present in the urine. Most (about 70%) of the CYMBALTA dose appears I the urine as metabolites of CYMBALTA; about 20% is excreted in the feces.

  Smoking Status – CYMBALTA bioavailability (AUC) appears to be reduced by about one-third in smokers. Dosage modifications are not recommended for smokers. Back to top of page

  Race – No specific pharmacokinetic study was conducted to investigate the effects of race.

  Renal Insufficiency – Limited data are available on the effects of CYMBALTA in patients with end stage renal disease (ESRD). After a single 60-mg dose of CYMBALTA, Cmax and AUC values were approximately 100% greater inpatients with end stage renal disease receiving chronic intermittent hemodialysis than in subjects with normal renal fuction. The elimination half-life, however, was similar in both groups. The AUC’s of the major circulation metabolites, 4-hydroxy duloxetine glucuronide and 5-hydroxy, 6-methoxy duloxetine sulfate, largely excreted in urine, were approximately 7 – to 9 – fold higher and would be expected to increase further with multiple dosing. For this reason, CYMBALTA is not recommended for patients with ESRD (see DOSAGE AND ADMINISTATION). Studies have not been conducted in patients with a moderate degree of renal dysfunction, but population PK analyses suggest that mild renal dysfunction has no significant effect on CYMBALTA apparent clearance.

Hepatic Insufficiency – Patients with clinically evident hepatic insufficiency have decreased CYMBALTA metabolism and elimination. After a single 20-mg dose of CYMBALTA 6 cirrhotic patients with moderate liver impairment (Child-Pugh Class B) had a mean plasma CYMBALTA clearance about 15% that of age- and gender-matched healthy subjects, with a 5-fold increase in mean exposure (AUC). Although Cmax was similar to normals in the cirrhotic patients, the half-life was about 3 times longer (see PRECAUTIONS). It is recommended that CYMBALTA no be administered to patients with any hepatic insufficiency (see DOSAGE AND ADMINISTRATION).   Back to top of page

Drug-Drug Interactions (also see PRECAUTIONS, Drug Interactions)

Potential for Other Drugs to Affect CYMBALTA.

  Both CYP1A2 and CYP2D6 are responsible for CYMBALTA metabolism.

INDICATIONS AND USAGE

CYMBALTA is indicated for the treatment of major depressive disorder (MDD).

CONTRAINDICATIONS

Hypersensitivity

CYMBALTA is contraindicated in patients with a known hypersensitivity to the product.

WARNINGS Back to top of page

  Clinical Worsening and Suicide Risk – Patients with major depressive disorder, both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality), whether or not they are taking antidepressant medications, and this risk may persist until significant remission occurs. Although there was been a long-standing concern that antidepressants may have a role in inducing worsening of depression and the emergence of suicidality in certain patients, a causal role for antidepressants in inducing such behaviors has not been established. Nevertheless, patients being treated with antidepressants should be observed closely for clinical worsening and suicidality, especially at the beginning of a course of drug therapy, or at the time of dose changes, either increases of decreases.  Consideration should be given to changing the therapeutic regimen, including possibly discontinuing the medication, in patients whose depression is persistently worse or whose emergent suicidality is severe, abrupt in onset, or was not part of the patient’s presenting symptoms.

  Because of the possibility of co-morbidity between major depressive disorder and other psychiatric and nonpsychiatric disorders, the same precautions observed when treating patients with major depressive disorder should be observed when treating patients with other psychiatric and nonpsychiatric disorders.

  The following symptoms – anxiety, agitation, panic attacks, insomnia, irritability, hostility (aggressiveness), impulsivity, akathisia (psychomotor restlessness), hypomania, and mania – have been reported in adult and pediatric patients being treated with antidepressants for major depressive disorder as well as for other indications, both psychiatric and nonpsychiatric. Although a causal link between the emergence of such symptoms and either the worsening of depression and/or the emergence of suicidal impulses has not been established, consideration should be given to changing the therapeutic regimen, including possibly discontinuing the medications, in patients for whom such symptoms are severe, abrupt in onset, or were not part of the patient’s presenting symptoms.

  Families and caregivers of patients being treated with antidepressants for major depressive disorder or other indications, both psychiatric and nonpsychiatric, should be alerted about the need to monitor patients for the emergence of suicidality, and to report such symptoms immediately to health care providers. Prescriptions for CYMBALTA should be written for the smallest quantity of capsules consistent with good patient management, in order to reduce the risk of overdose.

  If the decision has been made to discontinue treatment, medication should be tapered, as rapidly as is feasible, but with recognition that abrupt discontinuation can be associated with certain symptoms (see PRECAUTIONS and DOSAGE AND ADMINISTRATION, Discontinuing CYMBALTA (duloxetine hydrochloride), for a description  of the risks of discontinuation of CYMBALTA).

Information of Patients Back to top of page

  Physicians are advised to discuss the following issues with patients for whom they prescribe CYMBALTA.

  Patients and their families should be encouraged to be alert to the emergence of anxiety, agitation, panic attacks, insomnia, irritability, hostility, impulsivity, akathisia, hypomania, mania, worsening of depression, and suicidal ideation, especially early during antidepressant treatment. Such symptoms should be reported to the patient’s physician, especially if they are severe, abrupt in onset, or were not part of the patient’s presenting symptoms.

  Any psychoactive drug may impair judgment, thinking, or motor skills.

Drug Interactions (also see CLINICAL PHARMACOLOGY, Drug – Drug

Interactions)

  Inhibitors of CYP2D6 – Because CYP2D6 is involved in CYMBALTA metabolism, concomitant use of CYMBALTA with potent inhibitors of CYP2D6 may result in higher concentrations of CYMBALTA. Paroxetine (20 mg QD) increased the concentration of CYMBALTA (40 mg QD) by about 60%, and greater degrees of inhibition are expected with higher doses of Paroxetine. Similar effect would be expected with other potent CYP2D6 inhibitors (e.g., fluoxetine, quinidine).

 ADVERSE REACTIONS Back to top of page

  CYMBALTA has been evaluated for safety in 2418 patients diagnosed with major depressive disorder who participated in multiple-dose premarketing trials, representing 1099 patient-years of exposure. Among these 2418 CYMBALTA treated patients, 1139 patients participated in eight 8- or 9- week, placebo-controlled trials at doses ranging from 40 to 120 mg/day, while the remaining 1279 patients were followed for up to 1 year in an open-label safety study using flexible doses from 80 to 120 mg/day. Two placebo-controlled studies with doses of 80 to 120 mg/day had 6- month maintenance extensions. Of these 2418 patients, 993 CYMBALTA-treated patients were exposed for at least 180 days and 445 CYMBALTA-treated patients were exposed for at least 1 year. Adverse reactions were assessed by collecting adverse events, results of physical examinations, vital signs, weights, laboratory analyses, and ECGs.

  Clinical investigators recorded adverse events using descriptive terminology of their own choosing. To provide a meaningful estimate of the proportion of individuals experiencing adverse events, grouping similar types of events into a smaller number of standardized event categories is necessary. In the tables and tabulations that follow, MedDRA terminology has been used to classify reported adverse events.

  The stated frequencies of adverse events represent the proportion of individuals who experienced, at least once, a treatment-emergent adverse event of the type listed. An event was considered treatment-emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation. Events reported during the studies were not necessarily caused by the therapy, and the frequencies do not reflect investigator impression (assessment) of causality.

  The cited figures provide the prescriber with some basis for estimating the relative contribution of drug and non-drug factors to the adverse event incidence rate in the population studied. The prescriber should be aware that the figures in the tables and tabulations cannot be used to predict the incidence of adverse events in the course of usual medical practice where patient characteristics and other factors differ from those that prevailed in the clinical trials. Similarly, the cited frequencies cannot be compared with figures obtained from other clinical investigations involving different treatments, uses, and investigators.

Adverse Events Reported as Reasons for Discontinuation of Treatment in Placebo-Controlled Trials

  Approximately 10% of the 1139 patients who received CYMBALTA in the placebo-controlled trials discontinued treatment due to an adverse event, compared with 4% of the 777 patients receiving placebo. Nausea (CYMBALTA 1.4%, placebo 0.1%) was the only common adverse event reported as reason for discontinuation and considered to be drug-related (i.e., discontinuation occurring in at least 1% of the CYMBALTA-treated patients and at a rate of at least twice that of placebo).

Adverse Events Occurring at an Incidence of 2% or More Among CYMBALTA-Treated Patients in Placebo-Controlled Trials Back to top of page

  Table 1 gives the incidence of treatment-emergent adverse events that occurred in 2% or more of patients treated with CYMBALTA in the acute phase of MDD placebo-controlled trials and with an incidence greater than placebo. The most commonly observed adverse events in CYMBALTA-treated MDD patients (incidence of 5% or greater and at least twice the incidence in placebo patients) were nausea; dry mouth; constipation; decreased appetite; fatigue; somnolence; and increased sweating.

Effects on Male and Female Sexual Function

  Although changes in sexual desire, sexual performance and sexual satisfaction often occur as manifestations of a psychiatric disorder, they may also be a consequence of pharmacologic treatment. Reliable estimates of the incidence and severity of untoward experiences involving sexual desire, performance and satisfaction are difficult to obtain, however, in part because patients and physicians may be reluctant to discuss them. Accordingly, estimates of the incidence of untoward sexual experience and performance cited in product labeling are likely to underestimate their actual incidence.

Other Adverse Events Observed During the Premarketing Evaluation of CYMBALTA

  Following is a list of modified MedDRA terms that reflect treatment-emergent adverse events as defined in the introduction to the ADVERSE REACTIONS section reported by patients treated with CYMBALTA at multiple doses throughout the dose range studied during any phase of a trial within the premarketing database. The events included are those not already listed elsewhere in ADVERSE REACTIONS and not considered in the WARNINGS and PRECAUTIONS sections, that were reported with an incidence of greater than or equal to 0.05%, are not common as background events and were considered possibly drug related (e.g., because of the drug’s pharmacology) or potentially important. Back to top of page

  It is important to emphasize that, although the events reported occurred during treatment with CYMBALTA, they were not necessarily caused by it. Events are further categorized by body system and listed in order of decreasing frequency according to the following definitions: frequent adverse events are those occurring in at least 1/100 patients (only those not already listed in the tabulated results from placebo-controlled trials appear in this listing); infrequent adverse events are those occurring in 1/100 to 1/1000 patients; rare events are those occurring in fewer than 1/1000 patients.

Discontinuing CYMBALTA (duloxetine hydrochloride) Back to top of page

  Symptoms associated with discontinuation of CYMBALTA and other SSRIs and SNRIs have been reported (see PRECAUTIONS). Patients should be monitored for these symptoms when discontinuing treatment. A gradual reduction in the dose rather than abrupt cessation is recommended whenever possible. If intolerable symptoms occur following a decrease in the dose or upon discontinuation of treatment, then resuming the previously prescribed dose may be considered. Subsequently, the physician may continue decreasing the dose but at a more gradual rate.

Cymbalta - Side Effects Defined

  1. Anorexia – No longer having a desire to eat.
     
  1. Apothous Stomatitis – Painful red and swollen open sores on a mucus membrane of the mouth commonly called a canker sore.
     
  1. Ataxia – Loss of the ability to move the body with coordination.
     
  1. Arterial Fibrillation – A condition of abnormal twitching of the muscles in the blood vessels that moves the oxygenated blood from the heart to the rest of the body.  The unusual twitching is rapid and irregular and replaces the normal rhythm of contraction of the muscle, which sometimes causes a lack of circulation and pulse.
     
  1. Blood Cholesterol Increased – An abnormal condition where there is a greater amount in the blood of the oily/fatty substances known as cholesterol.   Cholesterol is a necessary part of living cells (along with proteins and carbohydrates).  Because cholesterol only slightly dissolves in water, it can build up on the walls of the blood vessels, therefore blocking/decreasing the amount of blood flow, which causes blood pressure to go up.  If not corrected, this condition is associated with coronary artery disease.
     
  1. Blood Creatinine Increased – A greater than normal number of creatinine or muscular chemical waste molecules in the blood.  Creatinine plays a major role in energy production in muscles.  Since creatinine levels are normally maintained by the kidneys, Blood Creatinine Increased is an indicator of kidney malfunction or failure.
     
  1. Blood in Stool – The blood that is in your bowel movement usually comes from any place along your digestive tract (from your mouth to your anus).  The stool can appear black and foul-smelling (usually from the upper part of your digestive tract) or red or maroon-colored (usually from the large intestine area).  Hemorrhoids are the usual cause for blood in the bowels.

8.       Bundle Branch Block Right – These are specialized cells in the upper right heart chamber and are the heart’s pacemaker.  They send electrical signals to the heart that keeps it beating or contracting regularly.  Normally the signal goes to the lower heart chambers at the same time through the bundle of His (hiss) on both the left and right sides of the heart, so the lower chambers contract at the same time.  When the bundle is damaged on the right side, the signal does not fire at the same time as the left, which changes the pace of blood flow.  This can lead to a person fainting.

  1. Cardiac Failure – A heart disorder where the heart does not function as usual and may completely stop working.
     
  1. Cardiac Failure Congestive – The body is asking for the heart to supply more blood than it is capable of producing and maintaining.  Normally, a body can tolerate an increased amount of work for quite some time.  The condition is characterized by weakness, shortness of breath, and a fluid build-up in the body tissues causing swelling.
     
  1. Cold Sweat – The skin is clammy and moist and you feel chilled.  This is a reaction to a shock or pain as well as to fear and nervousness.
     
  1. Colitis – A condition where the large intestine becomes irritated from the use of the drug.
     
  1. Coronary Artery Disease – A condition where the blood vessels that mainly carry the blood away from the heart become clogged up or narrowed usually by fatty deposits.  The first symptom is pain spreading from the upper left body caused by not enough oxygen reaching the heart.
     
  1. Dehydration – An extreme loss of water from the body or the organs of the body as in sickness or not drinking enough fluids.
     
  1. Diplopia – The condition where a person is looking a one object and instead of normally seeing just the one object he sees two.  This is also call double vision.
     
  1. Diverticulitis – There are pouches or sacs on the inside of the intestines that look like fingers.  This increases the area for the body to absorb nutrients as they pass through the intestines.  These sacs become irritated and swollen and end up trapping waste that would normally be eliminated, causing pain and constipation.
     
  1. Dysarthria – The inability to control the mouth muscles when forming words so the words are not clearly spoken and heard.
     
  1. Dyslipidemia – The normal fat metabolism in the blood is interfered with.
     
  1. Dysphagia – Trouble swallowing or the inability to swallow.
     
  1. Ecchymosis – When a blood vessel breaks and creates a purple discoloration of the skin.
     
  1. Edema – An abnormal build up of excess fluids in the cells, tissues, and the spaces between the tissues creating swelling.
     
  1. Edema Peripheral – The abnormal build up of fluids in the tissues of the ankles and legs causing painless swelling in the legs, ankles, and feet.  If you squeeze the swollen area it leaves an indentation on the skin for a few minutes.
     
  1. Ejaculation Delayed – The man is not able to release sperm either during sexual intercourse or with manual stimulation in the presence of his sexual partner in spite of his wish to do so.
     
  1. Ejaculation Dysfunction – A condition where the man has one or more of the following symptoms:  He is not able to have an erection, not able to have an orgasm, has a decreased interest in sex, is sexually inhibited, or it is painful to ejaculate sperm.
     
  1. Erectile Dysfunction – Incapable of having sexual intercourse.  Even though a man desires sex he is inhibited in his sexual activity and is unable to have or maintain an erection of the penis.
     
  1. Erythema – a skin redness caused by the swelling with blood of the tiny blood vessels of the skin as in burns.

Venlafaxine is a phenethylamine bicyclic derivative, chemically unrelated to tricyclic, tetracyclic or other available antidepressant agents.

The mechanism of venlafaxine's antidepressant action in humans is believed to be associated with its potentiation of neurotransmitter activity in the CNS. Preclinical studies have shown that venlafaxine and its major metabolite, O-desmethylvenlafaxine (ODV), are potent inhibitors of neuronal serotonin and norepinephrine reuptake and weak inhibitors of dopamine reuptake.

Venlafaxine and ODV have no significant affinity for muscarinic, histaminergic, or alpha1-adrenergic receptors in vitro. Pharmacologic activity at these receptors is hypothesized to be associated with the various anticholinergic, sedative, and cardiovascular effects seen with other psychotropic drugs. Venlafaxine and ODV do not possess monoamine oxidase (MAO) inhibitory activity.

Pharmacokinetics:
Venlafaxine is well absorbed, with peak plasma concentrations occurring approximately 2 hours after dosing. Venlafaxine is extensively metabolized, with O-desmethylvenlafaxine, (ODV, the only major active metabolite) peak plasma levels occurring approximately 4 hours after dosing. Following single doses of 25 to 75 mg, mean (+/- SD) peak plasma concentrations of venlafaxine range from 34+/-14 to 96+/-43 ng/mL, respectively, and are reached in 2+/-1 hours, and mean peak ODV plasma concentrations range from 58+/-18 to 178+/-40 ng/mL and are reached in 4+/-2 hours. Approximately 87% of a single dose of venlafaxine is recovered in the urine within 48 hours as either unchanged venlafaxine (5%), unconjugated ODV (30%), conjugated ODV (26%), or other minor metabolites (27%).

Multiple-Dose Pharmacokinetic Profile:
Steady-state concentrations of both venlafaxine and ODV in plasma were attained after approximately 3 days of multiple dose therapy. The clearance of venlafaxine is slightly (15%) lower following multiple doses than following a single dose.

Venlafaxine and ODV exhibited linear kinetics over the dose range of 75 to 450 mg total daily dose administered t.i.d.

The mean +/- SD steady-state plasma clearances of venlafaxine and ODV are 1.3+/-0.6 and 0.4+/-0.2 L/h/kg, respectively; elimination half-life is 5+/-2 and 11+/-2 hours, respectively.

Venlafaxine and ODV renal clearances are 49+/-27 and 94+/-56 mL/h/kg, respectively, which correspond to 5+/-3.0% and 25+/-13% of an administered venlafaxine dose recovered in urine as venlafaxine and ODV, respectively. Similar steady-state volumes of distribution are exhibited for venlafaxine (7+/-4 L/kg) and ODV (6+/-2 L/kg).

Venlafaxine and ODV are less than 35% bound to plasma proteins. Therefore, protein-binding-induced drug interactions with venlafaxine are not expected.

Food has no significant effect on the absorption of venlafaxine.

When equal daily doses of venlafaxine were administered either b.i.d. or t.i.d., drug exposure (AUC) and fluctuation in plasma levels were comparable.

Age and Gender:
Age and sex do not significantly affect the pharmacokinetics of venlafaxine. A 20% reduction in clearance was noted for ODV in subjects over 60 years old; this was possibly caused by the decrease in renal function that typically occurs with aging. Dosage adjustment based upon age or gender is generally not necessary (See Dosage).

Hepatic Disease:
In 9 patients with hepatic cirrhosis, the pharmacokinetic disposition of both venlafaxine and ODV were significantly altered. Venlafaxine elimination half-life was prolonged by about 30%, and clearance was decreased by about 50%. ODV elimination half-life was also prolonged (by about 60%) and its clearance decreased by about 30%. Three patients with more severe cirrhosis had a 90% decrease in venlafaxine clearance. Dosage adjustment is necessary in patients with liver disease (See Dosage).

Renal Disease:
In patients with moderate to severe impairment of renal function (GFR=10-70 mL/min), venlafaxine elimination half-life was prolonged by 50%, and clearance was deceased by about 24%. ODV elimination half-life was prolonged by about 40%, but clearance was unchanged. In dialysis patients, venlafaxine elimination half-life was prolonged by about 180% and clearance was decreased by about 56%. Dosage adjustment is necessary in patients with renal disease (See Dosage).

 


Indications

For the symptomatic relief of depressive illness.

The effectiveness of venlafaxine in long-term use (i.e., for more than 4 to 6 weeks) has not been systematically evaluated in controlled trials. Therefore, the physician who elects to use venlafaxine for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.

 


Contraindications

Patients with known hypersensitivity to venlafaxine or to any of the components of the formulation.

MAO Inhibitors:
There have been reports of serious, sometimes fatal reactions in patients receiving antidepressants with pharmacological properties similar to those of venlafaxine in combination with a MAO inhibitor. Therefore, venlafaxine should not be used in combination with MAO inhibitors or within two weeks of terminating treatment with MAO inhibitor's. Treatment with MAO inhibitors should not be started until two weeks after discontinuation of venlafaxine therapy.

 


Warnings

Sustained Hypertension:
Treatment with venlafaxine was associated with modest but sustained increases in blood pressure during premarketing studies. Sustained hypertension, defined as treatment-emergent supine diastolic blood pressure (SDBP) >= 90 mm Hg and 10 mm Hg above baseline for 3 consecutive visits, showed the following incidence and dose-relationship in Table I.

   101-200 mg/day             5%
   201-300 mg/day             7%
      >300 mg/day              13%
        Placebo                      2%
-----------------------------------------------

An analysis of the blood pressure increases in patients with sustained hypertension and in the 19 patients who were discontinued from treatment because of hypertension (<1% of total venlafaxine-treated group) showed that most of the blood pressure increases were in the range of 10 to 15 mm Hg, SDBP. Since in individual patients sustained increases of this magnitude could have adverse consequences, it is recommended that patients receiving venlafaxine have their blood pressure monitored regularly.

For patients who experience a sustained increase in blood pressure during treatment with venlafaxine, either a dose reduction or discontinuation of venlafaxine should be considered.

 


Precautions

General:
Suicide:

The possibility of a suicide attempt in seriously depressed patients is inherent to the illness and may persist until significant remission occurs. Close supervision of high-risk patients should accompany initial drug therapy, and consideration should be given to the need for hospitalization. In order to reduce the risk of overdose, prescriptions for venlafaxine should be written for the smallest quantity of tablets consistent with good patient management.

Seizures:
During premarketing testing, seizures were reported in 8 out of 3082 venlafaxine-treated patients (0.26%). In 5 of the 8 cases, patents were receiving doses of 150 mg/day or less. However, patients with a history of convulsive disorders were excluded from most of these studies. venlafaxine should be used cautiously in patents with a history of seizures, and should be promptly discontinued in any patient who develops seizures.

Activation of Mania/Hypomania:
During Phase II and III trials, mania or hypomania occurred in 0.5% of venlafaxine-treated patients. Activation of mania/hypomania has also been reported in a small proportion of patients with major affective disorder who were treated with other marketed antidepressants. As with all antidepressants, venlafaxine should be used cautiously in patients with a history of mania.

Patients with Concomitant Illness:
Clinical experience with venlafaxine in patients with concomitant systemic illness is limited. Caution is advised in administering venlafaxine to patients with diseases or conditions that could affect hemodynamic responses or metabolism. Patients should be questioned about any prescripton or "over the counter drugs" that they are taking, or planning to take, since there is a potential for interactions.

Cardiac Disease:
Venlafaxine has not been evaluated or used to any appreciable extent in patients with a recent history of myocardial infarction or unstable heart disease. Patients with these diagnoses were systematically excluded from many clinical studies during the product's clinical trials. Evaluation of the electrocardiograms for 769 patients who received venlafaxine in 4- to 6 week double-blind trials showed that the incidence of trial-emergent conduction abnormalities did not differ from that with placebo. The mean heart rate was increased by about 4 beats per minute during treatment. Venlafaxine treatment has been associated with sustained hypertension (see Warnings).

Hepatic and Renal Disease:
In patients with hepatic or renal disease the pharmacokinetic disposition of both venlafaxine and ODV are significantly altered. Dosage adjustment is necessary in these patients (See Dosage).

Occupational Hazards:
Any psychoactive drug may impair judgement, thinking or motor skills. Therefore, patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that the drug treatment does not affect them adversely.

Pregnancy, Labor and Delivery:
There are no adequate and well controlled studies with venlafaxine in pregnant women. Therefore, venlafaxine should only be used during pregnancy if clearly needed.

Lactation:
It is not known whether venlafaxine or its metabolites are excreted in human milk. Because many drugs are excreted in human milk, lactating women should not nurse their infants while receiving venlafaxine.

Children:
Safety and efficacy in children below the age of 18 have not been established.

Geriatrics:
Of the 2,897 patients in Phase II and III trials, 357 (12%) were 65 years of age or older. No overall differences in effectiveness and safety were observed between these patients and younger patients. However, greater sensitivity of some older individuals cannot be ruled out.

Discontinuation Symptoms:
While the discontinuation effects of venlafaxine have not been systematically evaluated in controlled clinical trials, a retrospective survey of new events occurring during taper or following discontinuation revealed the following six events that occurred at an incidence of at least 5%, and for which the incidence for venlafaxine was at least twice the placebo incidence: asthenia, dizziness, headache, insomnia, nausea and nervousness. Therefore, it is recommended that the dosage be tapered gradually and the patient monitored (See Dosage).

Drug Interactions:
As with all drugs, the potential for interaction by a variety of mechanisms is a possibility.

Lithium:
The steady-state pharmacokinetics of venlafaxine administered as 50 mg every 8 hours was not affected when a single 600 mg oral dose of lithium was administered to 12 healthy male subjects. Venlafaxine had no effect on the pharmacokinetics of lithium. It should be noted that the venlafaxine dose was in the low end of the therapeutic dosage, as was the single lithium dose. The potential interaction of venlafaxine and lithium in clinical practice is unknown.

Diazepam:
The steady-state pharmacokinetics of venlafaxine administered as 50 mg every 8 hours was not affected when a single 10 mg oral dose of diazepam was administered to 18 healthy male subjects. Venlafaxine had no effect on the pharmacokinetics of diazepam or its active metabolite, desmethyidiazepam. It should be noted that the venlafaxine dose was in the low end of the therapeutic dosage, as was the single diazepam dose. The potential interaction of venlafaxine and diazepam in clinical practice is unknown.

Cimetidine:
Concomitant administration of cimetidine and venlafaxine in a steady-state study for both drugs in 18 healthy male subjects resulted in inhibition of first-pass metabolism of venlafaxine. The oral clearance of venlafaxine was reduced by about 43%, and the exposure (AUC) and maximum concentration (Cmax) of the drug were increased by about 60%. However, there was no effect on the pharmacokinetics of ODV. The overall pharmacological activity of venlafaxine plus ODV is expected to rise only slightly, and no dosage adjustment should be necessary for most subjects.

However, for patients with pre-existing hypertension, for elderly patients and for patients with hepatic or renal dysfunction, the interaction associated with the concomitant use of cimetidine and venlafaxine is not known and potentially could be more pronounced. Therefore, caution is advised in these patients.

Other CNS-Active Drugs:
The risk of using venlafaxine in combination with other CNS-active drugs (including alcohol) has not been systematically evaluated. Consequently, caution is advised if the concomitant administration of venlafaxine and such drugs is required.

Electroconvulsive Therapy:
There are no clinical data on the use of electroconvulsive therapy combined with venlafaxine treatment.

Cytochrome P450 IID6:
Venlafaxine is metabolized to its active metabolite, ODV, by cytochrome P450 IID6 Therefore, the potential exists for a drug interaction between venlafaxine and drugs that inhibit cytochrome P450-IID6 metabolism. Venlafaxine is a relatively weak inhibitor of cytochrome P450 IID6, however, the clinical significance of this finding is unknown.

Drug Abuse and Dependence:
Physical and Psychological Dependence:
In vitro studies revealed that venlafaxine has virtually no affinity for opiate, benzodiazepine, phencyclidine (PCP), or N-methyl-D-aspartic acid (NMDA) receptors. It has no significant CNS stimulant activity in rodents. In primate drug discrimination studies, venlafaxine showed no significant stimulant or depressant abuse liability.

While venlafaxine has not been systematically studied in clinical trials for its potential for abuse, there was no indication of drug-seeking behaviour in the clinical trials. However, it is not possible to predict on the basis of premarketing experience the extent to which a CNS active drug will be misused, diverted, and/or abused once marketed. Consequently, physicians should carefully evaluate patients for history of drug abuse and follow such patients closely, observing them for signs of misuse or abuse of venlafaxine (e.g., development of tolerance incrementation of dose, drug-seeking behaviour).

The most commonly observed adverse events associated with the use of venlafaxine (incidence of 5% or greater) and not seen at an equivalent incidence among placebo-treated patients (i.e., incidence for venlafaxine at least twice that for placebo), derived from the 1% incidence Table III, were asthenia, sweating, nausea, constipation, anorexia, vomiting, somnolence, dry mouth, dizziness nervousness, anxiety, tremor, blurred vision, and abnormal ejaculation/orgasm and impotence in men.

Adverse Reactions Associated with Discontinuation of Treatment:
Nineteen percent (537/2897) of venlafaxine-treated patients in Phase II and III depression studies discontinued treatment due to an adverse reaction (see Table II). The more common events (>=1%) associated with discontinuation of treatment and considered to be drug-related (i.e., those events associated with dropout at a rate approximately twice or greater for venlafaxine compared to placebo) included Table II.

Incidence in Controlled Trials:
Table III that follows enumerates adverse events that occurred at an incidence of 1% or more, and were more frequent than in the placebo group, among venlafaxine-treated patients who participated in 4- to 8-week placebo-controlled trials in which patients were administered doses in the range of 75 to 375 mg/day. Reported adverse events were classified using a standard COSTART-based Dictionary terminology.

Dose Dependency of Adverse Events:
A comparison of adverse event rates in a fixed-dose study comparing Effexor 75, 225, and 375 mg/day with placebo revealed a dose dependency for some of the more common adverse events associated with Effexor use, as shown in Table IV. The rule for including events was to enumerate those that occurred at an incidence of 5% or more for at least one of the venlafaxine groups and for which the incidence was at least twice the placebo incidence for at least one Effexor group. Tests for potential dose relationships for these events (Cochran-Armitage Test, with a criterion of exact 2-sided p-value <= 0.05) suggested a dose-dependency for several adverse events in this list, including chills, hypertension, anorexia, nausea, agitation, dizziness, somnolence, tremor, yawning, sweating, and abnormal ejaculation .

Adaptation to Certain Adverse Events:
Over a 6-week period, there was evidence of adaptation to some adverse events with continued therapy (e.g., dizziness and nausea), but less to other effects (e.g., abnormal ejaculation and dry mouth).

Vital Sign Changes:
Venlafaxine treatment (averaged over all dose groups) in clinical trials was associated with a mean increase in pulse rate of approximately 3 beats per minute, compared to no change for placebo. It was associated with mean increases in diastolic blood pressure ranging from 0.7 to 2.5 mm Hg averaged over all dose groups, compared to mean decreases ranging from O.9 to 3.8 mm Hg for placebo. However, there is a dose dependency for blood pressure increase (see Warnings).

Laboratory Changes:
Of the serum chemistry and hematology parameters monitored during clinical trials with venlafaxine, a statistically significant difference with placebo was seen only for serum cholesterol, i.e., patients treated with venlafaxine had mean increases from baseline of 3 mg/dL, a change of unknown clinical significance.

ECG Changes:
In an analysis of ECGs obtained in 769 patients treated with venlafaxine and 450 patients treated with placebo in controlled clinical trials, the only statistically significant difference observed was for heart rate, i.e., a mean increase from baseline of 4 beats per minute for venlafaxine.

Other Events Observed During the Premarketing Evaluation of Venlafaxine:
During its premarketing assessment, multiple doses of venlafaxine were administered to 2,181 patients in phase II and III studies. The conditions and duration of exposure of venlafaxine varied greatly, and included (in overlapping categories) open and double-blind studies, uncontrolled and controlled studies, inpatient and outpatient studies, fixed-dose and titration studies. Untoward events associated with this exposure were recorded by clinical investigators using terminology of their own choosing. Consequently, it is not possible to provide a meaningful estimate of the proportion of individuals experiencing adverse events without first grouping similar types of untoward events into a smaller number of standardized event categories.

In the tabulations that follow, reported adverse events were classified using a standard COSTART-based dictionary terminology . The frequencies presented, therefore, represent the proportion of the 2,181 patients exposed to multiple doses of venlafaxine who experienced an event of the type cited on at least one occasion while receiving venlafaxine. All reported events are included except those already listed in Table III and those events for which a drug cause was remote. If the COSTART term for an event was so general as to be uninformative, it was replaced with a more informative term. It is important to emphasize that, although the events reported occurred during treatment with venlafaxine, they were not necessarily caused by it.

Events are further classified by body system and listed in order of decreasing frequency according to the following definitions: frequent adverse events are those occurring on one or more occasions in at least 1/100 patients (only those not already listed in the tabulated results from placebo controlled trials appear in this listing); infrequent adverse events are those occurring in 1/100 to 1/1000 patients; rare events are those occurring in fewer than 1/1000 patients. The frequent adverse events have been provided below.

Body as a whole: accidental injury, malaise, neck pain.
Cardiovascular: migraine.
Digestive: dysphagia, eructation.
Hemic and lymphatic: ecchymosis.
Metabolic and nutritional: peripheral edema, weight gain.
Nervous: emotional lability, trismus, vertigo.
Respiratory: bronchitis, dyspnea.
Special senses: abnormal vision, ear pain.
Urogenital: anorgasmia, dysuria, hematuria, metrorrhagia*, urination impaired, vaginitis*.

* Based on the number of male or female patients as appropriate.

 


Overdose

Symptoms and Treatment:

Human Experience:
There were 14 reports of acute overdose with venlafaxine, either alone or in combination with other drugs and/or alcohol, among the patients included in the premarketing evaluation. The majority of the reports involved ingestions in which the total dose of venlafaxine taken was estimated to be no more than several-fold higher than the usual therapeutic dose. The 3 patients who took the highest doses were estimated to have ingested approximately 6.75 g, 2.75 g and 2.5 g. The resultant peak plasma levels of venlafaxine for the latter 2 patients were 6.24 and 2.35 mcg/mL, respectively and the peak plasma levels of O-desmethylvenlafaxine were 3.37 and 1.30 mcg/mL, respectively. Plasma venlafaxine levels were not obtained for the patient who ingested 6.75 g of venlafaxine. All 14 patients recovered without sequelae. Most patients reported no symptoms. Among the remaining patients, somnolence was the most commonly reported symptom. The patient who ingested 2.75 g of venlafaxine was observed to have 2 generalized convulsions and a prolongation of QTc to 500 msec, compared with 405 msec at baseline. Mild sinus tachycardia was reported in 2 of the other patients.

Overdosage Management:
Treatment should consist of those general measures employed in the management of overdosage with any antidepressant. Ensure an adequate airway, oxygenation, and ventilation. Monitoring of cardiac rhythm and vital signs is recommended. General supportive and symptomatic measures are also recommended. Use of activated charcoal, induction of emesis, or gastric lavage should be considered. Due to the large volume of distribution of venlafaxine hydrochloride, forced diuresis, dialysis, hemoperfusion and exchange transfusion are unlikely to be of benefit. No specific antidotes for venlafaxine are known.

In managing overdosage, consider the possibility of multiple drug involvement. The physician should consider contacting a poison control centre on the treatment of any overdose.

 


Dosage

Adults:
The recommended treatment dose is 75 mg per day, administered in two or three divided doses, taken with food. If the expected clinical improvement does not occur after a few weeks, a gradual dose increase to 150 mg/day may be considered. If needed, the dose may be further increased up to 225 mg/day. Increments of up to 75 mg/day should be made at intervals of no less than 4 days. In outpatient settings there was no evidence of the usefulness of doses greater than 225 mg/day for moderately depressed patients. More severely depressed inpatients have responded to higher doses, between 350 and 375 mg/day, given in 3 divided doses.

Maximum:
The maximum dose recommended is 375 mg per day (in an inpatient setting).

Patients With Hepatic Impairment:
Given the decrease in clearance and increase in elimination half-life for both venlafaxine and ODV that is observed in patients with hepatic cirrhosis compared to normal subjects (see Pharmacology), it is recommended that the total daily dose be reduced by about 50% in patients with moderate hepatic impairment. Since there was much individual variability in clearance between patients with cirrhosis, it may be necessary to reduce the dose even more than 50%, and individualization of dosing may be desirable in some patients.

Patients with Renal Impairment:
Given the decrease in clearance for venlafaxine and increase in elimination half-life for both venlafaxine and ODV that is observed in patients with renal impairment (GFR = 10 to 70 mL/min) compared to normals (see Pharmacology), it is recommended that the total daily dose be decreased by 25% in patients with mild to moderate renal impairment. It is recommended that the total daily dose be reduced by 50% and the dose be withheld until the dialysis treatment is completed (4 hrs) in patients undergoing hemodialysis. Since there was so much individual variability in clearance between patients with renal impairment, individualization of dosing may be desirable in some patients.

Geriatrics:
No dose adjustment is recommended for elderly patients on the basis of their age. As with any antidepressant, however, caution should be exercised in treating the elderly. When individualizing the dosage, extra care should be taken when increasing the dose.

Discontinuing Venlafaxine:
When venlafaxine therapy that has been administered for more than 1 week is stopped, it is generally recommended that the dose be tapered gradually to minimize the risk of discontinuation symptoms. Patients who have received venlafaxine for 6 weeks or more should have their dose tapered gradually over a 2-week period.

Weight Gain/Weight Loss

Although not reported as a side-effect of this particular SSRI, weight gain has been reported to us on many occasions as a side-effect of Lexapro. Weight loss is also a possibility due to digestion disorders caused by the drug.  This is a very dangerous way to lose weight, however, and we emphatically don't recommend it. 

Should You Take Lexapro?

The answer is, of course, up to you.  Bear in mind the dangers and side-effects listed above.

You should also be tested for a dangerous drug metabolism issue before consumption of this or similar drugs.

Lexapro Side Effects, as described by people that have taken Lexapro

  • "I was prescribed Lexapro for anxiety.  You know, needed to get everything done in the world, like yesterday.  I was prescribed 10 mg a day.  After the first dose I started feeling lightheaded, dizzy and had an excruciating pain at the base of my skull that would sometimes work up and over the top of my head.  I have had this for a month now.  I have felt dizzy and lightheaded and am really tired.  I yawn a lot, even when I am wide awake and at work.  Sometimes I don't sleep well at night either.  Loss of libido and loss of appetite are both things that I have noticed.  My husband notices that I don't cry or scream when things aren't done any more, but I feel after three weeks this enough.  I will not be taking this medication any longer.  Thanks for the opportunity of telling you how Lexapro has worked for me."
  • "The only symptom I have experienced so far from Lexapro is drowsiness."
  • **** "My 19 year old brother was on Lexapro and he couldn't sleep, he hardly ate and he became very angry at times.  He was never suicidal before this medication but after being on it for 30 days he killed himself. Please make sure you really need this drug.  It may cost you your life."
  • "I have gained about 10 pounds recently, heart palpitations have returned, and I'm occasionally shaky. I'd like to stop the drug now and try natural methods -- relaxation techniques, yoga, breathing exercises -- to deal with my grief-related depression and anxiety."
  • "I hate it. It has done ZERO for my depression and only made me exhausted all the time. Then I cut back and I'm just as depressed as before, only less exhausted. Its been a month or two, and I am quitting as it is useless in my opinion. Also I have no appetite. No motivation. And I don't care a fig. So much for this med."
  • "I am on Lexapro, have been for about 6 months, have gained a lot of weight, about 35lb and having a lot of trouble getting it off I am ready to give up don't know what is worse the depression or the weight gain and being depressed about that and sweating like a man."
  • "I suffered significant memory loss, impaired judgment, mania then became zombie-like. I think this is a horrible drug. Needless to say, I got off of it."
  • "I have been taking Lexapro.
    Actually, it is more appropriate to say that I used to take this so called medication. After several years of taking one anti-depressant after the other, I have finally decided that these pills are nothing more than legalized poisons!
  • The last four years of my life are nothing more than a distorted blur. I now realize that I have been "daydreaming" all this time. I cannot remember what I did two days ago, and I can barely remember what I did the day after that; today has been nothing short of pointless.

    Before Lexapro, there was Effexor, and then Zoloft. But in my lifetime I have also been on Prozac, Wellbutrin, and at least ten other medications I don't even remember the names of. And I honestly can't imagine why I allowed myself to take any of these for such a long time. I have spent the last four years of my life waning in this very room. I might as well be dead, and to be honest, I wish I were. But that thought is nothing new or surprising to me. All the things I used to think I were?--stupid, useless, overweight--it's all come to pass. And at the moment I am too confused and weak to even think about what to do. All I could do was simply stop taking everything.

    And it's been hell so far. It's like I am always standing beside a railroad, and every fifteen seconds a train going 200 MPH passes me by. It's as if there's a microchip in my brain, and someone's pressing a button to shock me for their personal amusement! How much longer can this withdrawal last?

    All wailing aside, the thing I find most disturbing about this whole ordeal is--why did my doctor do this? I trusted her. I never wondered why, when one medication wasn't doing the trick, she would just cheerfully write a prescription for something else. It's as if she had a long list of new drugs she wanted to try, and I was her zombified guinea pig. Is there some kind of pay raise for taking on such a role? I'd really like to know how someone could have such disregard for another person. I was never told of side-effects, or consequences. I just did what I was told. And it has turned me into a weak-minded, mind-wandering idiot. If I weren't so drug-addled, I could've spent the last four years of my life going to school. I can't even hold a simple job at Taco Bell in this state.

    Anyway, there I go again. I can't help it, though. It's an outrage. I refuse to take another FDA-approved drug again for as long as I live. I believe it all just boils down to money, no matter who gets hurt. Who cares, right? I'm just some loser with Depression.

    I know I'm supposed to use this for listing side-effects, right? Well, there're many. To be direct, this pill does not treat depression, it ENCOURAGES depression, and throws you into a state in which you can never escape the very thing it is supposed to relieve.

    --Indifference: My uncle, who was more like my father than my actual father, died a year ago. Did I cry? Did I even attend his funeral? Do I even feel the pain of losing him at this very moment? No. Most of the time, I do not feel anything at all. It takes 1) A very extraordinary event to make me laugh, cry or feel excited, or; 2) A very long time. Eventually, the little things do add up into one huge explosive outburst. There is only one emotion that I feel frequently, and that is ANGER.

    --Lack of Energy: I used to think I wasn't active before, but this is a severe case of lethargy. I'm not just talking about a lack of motivation, but a lack of normal breathing. My breathing is very shallow, and only those with very good hearing can understand what I say, even if I'm right next to them when I speak. There have even been times when I have lost the feeling in my face, mouth, gums, etc., and thought I was dying of a heart attack or some other trauma.

    --Weight Gain: My eating habits never changed, but I somehow managed to gain 90 lbs., from 180 to 270, during the time I've been on Lexapro.
    --Inflamed Joints: My right wrist (I am right-handed) constantly burns. Sometimes the whole hand burns and tingles, and I lose control of it for a short time.
    --Irritability: All the bad things--jealousy, bitterness, etc.--are seemingly always present. Who wants to be mad at the world for the rest of their life? It is a miserable way to live!

    --Tightness of Scalp: This could just be a weird form of headache, or perhaps stress. Try to imagine that your day has gone to hell, and you begin to get frustrated and you think very unpleasant thoughts as a result. You know that tightness on your forehead as you contort your eyebrows to look "angry"? Well, that's always there. It's been there for so long, I can't even imagine what it would be like without it!
    --Suicidal Thoughts: Wow, who would've thought that one of the worst results of Depression--the very disorder that this pill is supposed to combat--is a side effect? Blows your mind, huh!

    --Faulty Memory: Yes, I can honestly say that I am a 28-year-old who feels like a feebleminded 90-year-old. I'm actually surprised that I am able to write this. Trust me, it would be more coherent and concise if I had full use of my brain."
  • "Although my doctor informed that acne is not a side-effect of Lexapro when I asked, I am certain that this non-stop break out (and unusual for me weight gain) is directly related to the drug.  Thank you for your website.  I went to Lexapro's site to see if acne or weight gain was listed in small type somewhere, but found only a small mention of any side-effects, really.

    ???  Don't know if anyone else has reported acne.  The weight gain is actually something I can live with, but the acne ... high school all over again ... talk about depression!"

  • "My son, age 15, was recently put on Lexapro 20mg by a nurse practitioner. this drug was also recommended by my son's therapist. I am concerned about the side effects of this drug. should he be monitored by a psychiatrist? should he be taking this medication; he stays up very late at night, doesn't eat much, and can become irritable. In fact last week he had a major mood swing that resulted in the police coming to our home. I am concerned about the effects this medication may be having on him."
  • "I just took it for the first time today I have experienced...nausea...dry mouth ..rapid heart beat...shaking...a feeling of wanting to jump out of my skin.....I will never take it again! I was taking it for anxiety and mild depression."
  • "Lexapro was prescribed for PMS and pre menopause symptoms.  Side effects include fatigue, constipation, loss of appetite."
  • "I have been taking Lexapro for 4 months.  I was prescribed this drug for major postpartum depression.  I was concerned about weight gain, and my psychiatrist assured me that weight gain isn't a factor with this medication.  I have experienced severe constipation, total loss of sexual desire, and have gained weight (about 10 lbs. - can't figure out if it's due to the medicine or increased appetite, which could be due to the medicine anyhow).  I'm going to taper off and get off medicines completely and start using natural remedies for depression."
  • "Taking Lexapro for depression. Stomach pain, sleepy all day, constipation and diarrhea, headache as side effects."
  • "When I tried to come off of 20 mg of Lexapro I was thrown in to these huge withdrawal flashings in my head shaking, sweating, uncontrollable crying.  It  has been very difficult to come off of.  My Dr. took me off cold turkey like the morons that they are and I put myself back on and am going to taper off monthly."
  • "When I was on Lexapro I couldn't even tell if I felt horrible, or better, or sick...I just couldn't even think well enough to say what I was feeling.  Now I know that I was rapid cycling through manic and depressive episodes but during the time I just couldn't keep anything straight. My answers to my parents were always "I don't know, just leave me alone.""
  • "I took one Lexapro in late January.  It woke me up in the middle of the night with bizarre feelings in the head.  The next day I had ringing in my ears and stopped taking it then and there.  I am still coping with ringing in my ear to this day--as well as occasional pains on the right side of my head.  Even had a CAT scan--which showed everything "normal", thank God.  Doctor says it was just a coincidence and my Tinnitis is due to some virus or allergy.  Yea, I believe it to be an allergy--one most likely triggered by that one dose of Lexapro.  Now I feel like I have arthritis of the head, if that were possible.  Thank God it usually isn't severe, but I still want it to end."
  • "I began taking 10mg Lexapro for depression. My Dr. told me of mild side effects that would go away. The first three days I experienced nausea, fatigue, insomnia, excessive sweating and my depression got worse. The next two days I had migraine headaches. I have never been treated for depression before but I do know that this stuff is terrible. I stopped taking Lexapro and my side effects are subsiding."
  • "I think this should be added to your site...
    I went to the DR and she gave me a few boxes of Lexapro (7 pills to a box)  I didn't even finish 1 box and I was getting all these dry red blotches all over my face and arms. It looked like the underneath of a sun burn you peeled off.  PLUS I was getting very moody and angry.  I don't think that's very good for someone who was suicidal! Can we say DUH!

    Now I'm on Celexa and I have the jitters all the time .. shaky foot etc. and the Dr gave me oh such a wonderful answer... "All Meds are going to give you some kind of side affect, we just have to try some different ones until we find side affects that you can deal with"  WHAT??? am I lab rat now?  Jeeeez!  I'm not asking for a miracle cure, but I'd rather have my depression then the shakes or worse."
  • "My experience with Lexapro is negative.  I am experiencing too many side effects, such as muscles twitching, reduced ability to sleep for prolonged periods of time, dumbed down emotions, and a occasional suicidal thought-not previously contemplated."
  • "Three hours after my first dose of Lexapro my blood pressure shot up to 180/120 and my pulse raced to 170.  I was transported to the ER where the ER Doctor said he doubted that the Lexapro caused the problem.  He said the only way to find out was to take it again.  He diagnosed me with an irregular heartbeat.  Three weeks later, I tried another dose of Lexapro, the exact same thing happened!  Beware!!"
  • "Seizures"
  • "Weight gain, somnolence, dizziness and decreased libido."
  • "I thought something was wrong with me! I have the worst migraines ever and my brow is constantly furied and my left eye needs to be shut a lot to ease the pain. I have very disturbing nightmares and dreams that seem very real. I get  hot and cold all the time and sweat a lot more than usual. My memory is very scary. I can't remember the most simple things. I can't even hold a conversation because my thinking is just off."
  • "It was prescribed for me to help me deal with the pain associated with my recently diagnosed Fibromylgia symptoms and my weight gain due to newly discovered under active thyroid. I took the Lexapro only one morning and was nauseated all morning as well as drowsy and dizzy (this was while I was as work). I was told that if I continued it, I should probably feel better, but I'm leery about mind-altering medications so I think I may just tough-it-out. Thanks for having this page available."
  • "The last medication that I was on was Lexapro and Celexa. Both made me feel better that other medication except that I could not walk, that's right, I could not walk. Both medicines created a feeling of arthritis in my knees. Once I stopped taking the medication the knees are ok."
  • "I am sure glad that I read about this drug Lexapro before taking it, I think I can do with out the side effects that I seen listed, I think I would rather go through the depression stages then go through the things I just read, thank you people for sharing the side affects that you had happen to you with this drug, sure help this person here, to know what can happen taking this drug, Thank God for speaking out what goes on with others, why are we guinea pigs for testing drugs, no wonder I got a sample instead of getting from the drug store, hmmm makes you wonder huh, I know one thing, I'm sure not taking them, got enough going on with my body and health to add another problem, Thanks again for speaking out, take care all... God Bless"
  • "Have taken only one pill-side effects are absolutely UNBELIEVABLE"
  • "I have been taking Lexapro for about a year.  At first, I had no problems adjusting to the drugs and it did wonders for my anxiety. However, I did try to wean myself off the medicine and experienced terrible migraines, nausea, and dizziness.  It was so bad, I had to go back on the drug and I have also gained about 15 pounds in the past year from it.  It also makes you extremely tired all of the time."
  • "I was prescribed Lexapro after having problems coming off Paxil.  Now I'm sleepy all the time, I've gained 12 lbs., I'm dizzy and have trouble concentrating.  The worst and most frightening this is the tremors I get a few hours after taking the 10mg dose."

Can Lexapro Treat Depression?

What is Depression?

Depression is defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association, this way: 

The essential feature of a Major Depressive Episode is a period of at least 2 weeks during which there is either depressed mood or the loss of interest or pleasure in nearly all activities.  In children and adolescents, the mood may be irritable rather than sad.  The individual must also experience at least four additional symptoms drawn from a list that includes major changes in appetite or weight, sleep, and psychomotor*  activity; decreased energy; feelings of worthlessness or guilt; difficulty thinking, concentrating, or making decisions; or recurrent thoughts of death or suicidal ideation, plans, or attempts."

Back to top of page

-----------------------------------------

* Of or relating to movement or muscular activity associated with mental processes.

-----------------------------------------

While these elements can certainly be seen to exist and have been experienced by many, labeling "depression" as an illness has been criticized by many as simply labeling part of life itself as a physical "disease" which must be "cured". 

This could be debated endlessly, however, and whole long texts have been written on the subject.  Depression as a state of mind certainly does exist, and can be painful.  The question to be addressed here, though, is, does Depression truly have a physical cause that can be addressed with medication?

For the answer, let's go back to the DSM.  The only information given there as to physical causes of depression is: 

Neurotransmitters implicated in the pathophysiology* of a Major Depressive Episode include norepinephrine, serotonin, acetylchlorine, dopamine, and gamma-aminobutryric acid. 

----------------------------------------

*Pathophysiology -- study of the physical effects of a disease.

----------------------------------------

All right, what does all that mean?  Here's a simple explanation. 

A neurotransmitter is a chemical that helps transmit nerve impulses through the nervous system.  There are many different neurotransmitters used by the body.  What the DSM definition is saying is that, by some method, the neurotransmitter chemicals known as  norepinephrine, serotonin, acetylchlorine, dopamine, and gamma-aminobutryric acid seemed to be lower in some depressed people, or higher in non-depressed people. 

Note carefully the use of the word implicated in the DSM definition, however.  And therein is the first clue, for it has never been clinically proven that depression is based in neurotransmitters.  We repeat:  Never.  And believe it or not, there is not a doctor on Earth that will disagree with that statement.

Which leads to the conclusion that a physical cause for depression has never been isolated.  Why, then, are psychiatrists and drug companies so insistent that Lexapro is a great treatment for depression?

That leads us to our next question.

Back to top of page

What is Lexapro?

Lexapro is a brand-name for a drug called escitalopram oxalate, and is technically classified as a Selective Serotonin Reuptake Inhibitor, or SSRI.

So what does all that mean?

Serotonin is a type of neurotransmitter.  We defined neurotransmitter in the last section. 

The way a neurotransmitter works is, it is passed along from one nerve to another.  A bit of it is sent out at a time from one nerve to the next.  After a bit is sent out and received by the next nerve, any of the neurotransmitter remaining between the nerves is taken back by the first nerve, a process called reuptake. 

An SSRI prevents this reuptake process from occurring, which means that, when Lexapro is active, the neurotransmitter serotonin is transmitted in a steady stream from one nerve ending to the next, instead of being sent in bits periodically, which it normally is. 

The word selective in Selective Serotonin Reuptake Inhibitor simply means that the drug "selects" only serotonin as a target, instead of neurotransmitters in general or a number of them. 

There are a number of SSRIs on the market, and these are all classified, along with Lexapro, as "anti-depressants."

Does Lexapro Cure Depression?

Good question.  If depression has never been proven to be caused by neurotransmitters (or the lack of them), that question cannot obviously be answered conclusively.

In fact, it cannot even be answered conclusively by Forest Pharmaceutical, manufacturers and marketers of Lexapro.  In the Lexapro section of their Web site, under "Lexapro FAQs", is written:  "It [depression] is believed to be caused by an imbalance of certain chemicals in the brain that affect mood."   "Lexapro helps to restore the brain's chemical balance by increasing the available supply of serotonin, a substance in the brain believed to influence mood."

Please note the assumptions in this text.  "It is believed to be caused by an imbalance of certain chemicals in the brain that affect mood."   "Lexapro helps to restore the brain's chemical balance by increasing the available supply of serotonin, a substance in the brain believed to influence mood." 

Translation:  Forest Pharmaceutical  playing a major guessing game with your mental health, and prescribing a highly dangerous drug to "treat" it. 

So again, why does Forest Pharmaceutical assert that Lexapro is such a great treatment for depression?  The answer, unfortunately, probably lies in the neighborhood of the dollar bill.  The first SSRI on the market was Eli Lilly and Company's Prozac, and Prozac became the best-selling drug of all-time.  When you announce broadly to the world that a common malady such as depression has been isolated as a "disease", and that there is now a drug to "cure" it, people are going to buy it. But money talks, the drug sold enormously, and hence numerous other drug companies followed suit and developed their own SSRIs.  They are still doing so, and Lexapro is just the next "new" treatment for depression.

You can tell a lot about medication with how the pharmaceutical company's stock is doing. It looks like Wall Street is getting wise to Lexapro early.

"NEW YORK, July 16 (New Ratings) - Analysts at First Albany maintain their "neutral" rating on Forest Laboratories (FRX), while lowering their estimates for the company. The target price has been reduced from $61 to $57.

In a research note published this morning, the analysts mention that the visibility on the company's long-term growth rate is poor. The performance of the company's drugs, Celexa and Lexapro, is likely to be below expectations, the analysts add. First Albany reduces its 2004 EPS estimate from $2.01 to $2.00."

The performance of Lexapro is sagging even with the push of the physicians and their drug reps. You know how Lexapro was pushed on you. Even with that, their market share is dropping.

"NEW YORK, July 18 (Reuters) - Can a pill be the answer for shoppers who go out to buy a battery and come home, quite inexplicably, with a plasma TV?

Forest Laboratories Inc. (NYSE:FRX - News) is sponsoring a trial at California's Stanford University designed to show that its antidepressants Celexa and Lexapro can cut down on compulsive shopping.

Both these drugs, part of a class known as selective serotonin reuptake inhibitors, or SSRIs, were first approved to treat depression.

But makers of SSRIs, which include Pfizer Inc. (NYSE:PFE - News), GlaxoSmithKline Plc (London:GSK.L - News) and Eli Lilly and Co.(NYSE:LLY - News), are seeking ever wider definitions of diseases that might accommodate their products."

*The Paxil - Seroxat side effects (underlined) listed below, are linked to case studies that have determined glutathione depletion and certain side effects go hand in hand. Almost all of the Paxil - Seroxat side effects listed below are a result of low glutathione in the cells of the body. Other case studies will be added ASAP. 

The chemical properties, in the structure of Paxil - Seroxat, lower glutathione levels in your cellular structure. A psychiatrist may have been the one to prescribe Paxil - Seroxat but a Chemist can easily determine why chemically induced Paxil - Seroxat side effects take place.

Prozac (Fluoxetine)

Side Effects

 

While Ely Lilly and Company, the manufacturers and marketers of Prozac, do issue a full list of side effects, which they must do under law, there is, unfortunately, no law that mandates that said list must be comprehensible by a layman.  We would venture to say that many doctors could not make it through this list with full understanding. 

 

It could be argued that the list of side effects was deliberately made not understandable.  If there were any reason for such, it would probably be that these potential side effects are quite serious, including such items as psychosis, breakdown of muscle control, heart attack, stroke, and even forms of cancer.  Perhaps the manufacturer did not want patients to understand it.  And, as written, they certainly would not. 

 

We have taken the time and trouble to put "plain English" translations next to the more obscure medical terms below.  You'll probably be as shocked as we were as we "translated" the list.

Side Effects Zoloft (sertraline hydrochloride)

Frequent Zoloft Side Effects

palpitations

 

chest pain

The above Zoloft side effects are FREQUENT. If you are thinking of taking Zoloft or prescribing Zoloft to a patient, please stop for a minute and evaluate what you are trying to cure with Zoloft. If you or your patient are currently depressed, how do you think it will be with all or most of the frequent side effects with you or your patient on a daily basis? Will it make things worse?

The above Zoloft side effects are taken from the Pfizer Premarketing clinical trials. 

What Zoloft side effects can you expect after more than a few weeks of usage?

The list below is taken from the Zoloft side effects (Postmarketing Evaluation)

acute renal failure

 

 

anaphylactoid reaction (Hypersensitivity to a foreign substance) angioedema (Excessive accumulation of fluid in the tissues)
blindness

 

 

optic neuritis (Inflammation, pain or loss of motion in the eye)


cataract





increased blood coagulation times




bradycardia (Slowness of the heart rate, usually fewer than 60 beats per minute in an adult human)
arrhythmias 
(An irregularity in the force or rhythm of the heartbeat)



Tachycardia 
(A rapid heart rate, especially one above 100 beats per minute in an adult)

Hypothyroidism (Insufficient production of thyroid hormones)



Agranulocytosis (An acute disease marked by high fever and a sharp drop in circulating granular white blood cells)

The above list of Zoloft side effects from Postmarketing Evaluation is actually much longer than listed here.

Deaths from Zoloft overdose have varied with the amounts taken. One patient ingested 13.5 grams and recovered while another ingested 2.5 grams and had a fatal outcome.
