ADVERSE REACTIONS SECTION The following adverse reactions are discussed in greater detail in other sections of the label: Hypersensitivity [see Contraindications ( 4.1 ) ] Suicidal Thoughts and Behaviors in Children, Adolescents, and Adults [see Warnings andPrecautions ( 5.1 ) ] Serotonin Syndrome [see Warnings and Precautions ( 5.2 ) ] Elevations in Blood Pressure [see Warnings and Precautions ( 5.3 ) ] Abnormal Bleeding [see Warnings and Precautions ( 5.4 ) ] Angle Closure Glaucoma [see Warnings and Precautions ( 5.5 ) ] Activation of Mania/Hypomania [see Warnings and Precautions ( 5.6 ) ] Discontinuation Syndrome [see Warnings and Precautions ( 5.7 ) ] Renal Impairment [see Warnings and Precautions ( 2.6 ) ] Hepatic Impairment [see Warnings and Precautions ( 2.6 ) ] Seizure [see Warnings and Precautions ( 5.8 ) ] Hyponatremia [see Warnings and Precautions ( 5.9 ) ] Weight and Height changes in Pediatric Patients [see Warnings and Precautions ( 5.10 ) ] Appetite Changes in Pediatric Patients [see Warnings and Precautions ( 5.11 ) ] Interstitial Lung Disease and Eosinophilic Pneumonia [see Warnings and Precautions ( 5.12 )] 6.1 Clinical Studies Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. Most Common Adverse Reactions The most commonly observed adverse reactions in the clinical study database in venlafaxine hydrochloride extended-release capsules treated patients in MDD, SAD, and PD (incidence ≥ 5% and at least twice the rate of placebo) were: nausea (30%), somnolence (15.3%), dry mouth (14.8%), sweating (11.4%), abnormal ejaculation (9.9%), anorexia (9.8%), constipation (9.3%), impotence (5.3%) and decreased libido (5.1%). Adverse Reactions Reported as Reasons for Discontinuation of Treatment Combined across short-term, placebo-controlled premarketing studies for all indications, 12% of the 3,558 patients who received venlafaxine hydrochloride extended-release capsules (37.5 to 225 mg) discontinued treatment due to an adverse experience, compared with 4% of the 2,197 placebo-treated patients in those studies. The most common adverse reactions leading to discontinuation in ≥ 1% of the venlafaxine hydrochloride extended-release capsules treated patients in the short-term studies (up to 12 weeks) across indications are shown in Table 7.

Across most indications, a dose-related increase in mean supine systolic and diastolic blood pressure was evident in patients treated with venlafaxine hydrochloride extended-release capsules. Across all clinical studies in MDD, SAD and PD, 1.4% of patients in the venlafaxine hydrochloride extended-release capsules groups experienced an increase in SDBP of ≥15 mm Hg along with a blood pressure ≥ 105 mm Hg, compared to 0.9% of patients in the placebo groups. Similarly, 1% of patients in the venlafaxine hydrochloride extended-release capsules groups experienced an increase in SSBP of ≥ 20 mm Hg with a blood pressure ≥ 180 mm Hg, compared to 0.3% of patients in the placebo groups.

Venlafaxine hydrochloride extended-release capsules treatment for up to 12 weeks and up to 6 months in premarketing placebo-controlled Social Anxiety Disorder trials was associated with mean final on-therapy increases in serum cholesterol concentration of approximately 7.9 mg/dL and 5.6 mg/dL, respectively, compared with mean final decreases of 2.9 and 4.2 mg/dL, respectively, for placebo. Venlafaxine hydrochloride extended-release capsules treatment for up to 12 weeks in premarketing placebo- controlled panic disorder trials was associated with mean final on-therapy increases in serum cholesterol concentration of approximately 5.8 mg/dL compared with a mean final decrease of 3.7 mg/dL for placebo. Patients treated with venlafaxine hydrochloride tablets for at least 3 months in placebo-controlled 12-month extension trials had a mean final on-therapy increase in total cholesterol of 9.1 mg/dL compared with a decrease of 7.1 mg/dL among placebo-treated patients. This increase was duration dependent over the study period and tended to be greater with higher doses. Clinically relevant increases in serum cholesterol, defined as 1) a final on-therapy increase in serum cholesterol ≥50 mg/dL from baseline and to a value ≥261 mg/dL, or 2) an average on-therapy increase in serum cholesterol ≥50 mg/dL from baseline and to a value ≥261 mg/dL, were recorded in 5.3% of venlafaxine-treated patients and 0% of placebo- treated patients. Serum Triglycerides Venlafaxine hydrochloride extended-release capsules was associated with mean final on-therapy increases in fasting serum triglycerides compared with placebo in premarketing clinical studies of SAD and PD up to 12 weeks (pooled data) and 6 months duration (Table 14).

As with adults, decreased appetite, weight loss, increased blood pressure, and increased serum cholesterol were observed [see Warnings and Precautions ( 5.3 , 5.10 , 5.11 ) and Use in Specific Populations ( 8.4 )]. In pediatric clinical studies, the adverse reaction, suicidal ideation, was observed. Particularly, the following adverse reactions were observed in pediatric patients: abdominal pain, agitation, dyspepsia, ecchymosis, epistaxis, and myalgia. 6.5 Adverse Reactions Identified During Postapproval Use The following adverse reactions have been identified during postapproval use of venlafaxine hydrochloride extended-release capsules. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure: Body as a whole Anaphylaxis, angioedema Cardiovascular system QT prolongation, ventricular fibrillation, ventricular tachycardia (including torsade de pointes) Digestive system Pancreatitis Hemic/Lymphatic system Mucous membrane bleeding [see Warnings and Precautions ( 5.4 )], blood dyscrasias (including agranulocytosis, aplastic anemia, neutropenia and pancytopenia), prolonged bleeding time, thrombocytopenia Metabolic/Nutritional Hyponatremia [see Warnings and Precautions ( 5.9 )], Syndrome of Inappropriate Antidiuretic Hormone (SIADH) secretion [see Warnings and Precautions ( 5.9 )], abnormal liver function tests, hepatitis, prolactin increased Musculoskeletal Rhabdomyolysis Nervous system Neuroleptic Malignant Syndrome (NMS) [see Warnings and Precautions ( 5.2 )], serotonergic syndrome [see Warnings and Precautions ( 5.2 )], delirium, extrapyramidal reactions (including dystonia and dyskinesia), impaired coordination and balance, tardive dyskinesia Respiratory system Pulmonary eosinophilia Skin and appendages Stevens-Johnson syndrome, toxic epidermal necrolysis, erythema multiforme Special senses Angle-closure glaucoma [see Warnings and Precautions ( 5.5 )]

CONTRAINDICATIONS SECTION 4.1 Hypersensitivity Hypersensitivity to venlafaxine hydrochloride, desvenlafaxine succinate or to any excipients in the formulation 4.2 Concomitant Use with Monoamine Oxidase Inhibitors (MAOIs) The use of MAOIs (intended to treat psychiatric disorders) concomitantly with venlafaxine hydrochloride extended-release capsules or within 7 days of discontinuing treatment with venlafaxine hydrochloride extended-release capsules are contraindicated because of an increased risk of serotonin syndrome. The use of venlafaxine hydrochloride extended-release capsules within 14 days of discontinuing treatment with an MAOI (intended to treat psychiatric disorders) is also contraindicated [see Dosage and Administration (2.9), Warnings and Precautions (5.2), and Drug Interactions (7.2)]. Starting venlafaxine hydrochloride extended-release capsules in a patient who is being treated with an MAOI such as linezolid or intravenous methylene blue is also contraindicated, because of an increased risk of serotonin syndrome [see Dosage and Administration (2.9), Warnings and Precautions (5.2), and Drug Interactions (7.3)].

DESCRIPTION SECTION Venlafaxine hydrochloride extended-release capsule, USP is an extended-release capsule for once-a-day oral administration that contains venlafaxine hydrochloride, a serotonin and norepinephrine reuptake inhibitor (SNRI). Venlafaxine is designated (R/S)-1-[2-(dimethylamino)-1-(4-methoxyphenyl)ethyl] cyclohexanol hydrochloride or (±)-1-[α- [(dimethylamino)methyl]-p-methoxybenzyl] cyclohexanol hydrochloride and has the molecular formula of C17H27NO2 HCl. Its molecular weight is 313.86. The structural formula is shown as follows: Venlafaxine hydrochloride, USP is a white to off-white crystalline powder; soluble in methanol and in water. Its octanol:water (0.2 M sodium chloride) partition coefficient is 0.43. Drug release is controlled by diffusion through the coating membrane on the spheroids and is not pH-dependent. Venlafaxine hydrochloride extended-release capsules, USP intended for oral administration contains 37.5 mg, 75 mg and 150 mg of venlafaxine. In addition, each capsule contains the following inactive ingredients: colloidal silicon dioxide, cetostearyl alcohol, gelatin, hypromellose, microcrystalline cellulose, polyacrylate dispersion, sodium lauryl sulfate, talc and titanium dioxide. Additionally each 37.5 mg capsule shell contains black iron oxide and each 75 mg and 150 mg capsule shell contains red iron oxide. The capsule is printed with black pharmaceutical ink which contains black iron oxide as coloring agent. The product complies with USP dissolution test 7. image description

DOSAGE & ADMINISTRATION SECTION Venlafaxine hydrochloride extended-release capsules should be administered in a single dose with food, either in the morning or in the evening at approximately the same time each day [see Clinical Pharmacology (12.3)]. Each capsule should be swallowed whole with fluid and not divided, crushed, chewed, or placed in water or it may be administered by carefully opening the capsule and sprinkling the entire contents on a spoonful of applesauce. This drug/food mixture should be swallowed immediately without chewing and followed with a glass of water to ensure complete swallowing of the pellets (spheroids). 2.1 Major Depressive Disorder For most patients, the recommended starting dose for venlafaxine hydrochloride extended-release capsules are 75 mg per day, administered in a single dose. For some patients, it may be desirable to start at 37.5 mg per day for 4 to 7 days to allow new patients to adjust to the medication before increasing to 75 mg per day. Patients not responding to the initial 75 mg per day dose may benefit from dose increases to a maximum of 225 mg per day. Dose increases should be in increments of up to 75 mg per day, as needed, and should be made at intervals of not less than 4 days, since steady-state plasma levels of venlafaxine and its major metabolites are achieved in most patients by day 4 [see Clinical Pharmacology (12.3)]. In the clinical studies establishing efficacy, upward titration was permitted at intervals of 2 weeks or more. It should be noted that, while the maximum recommended dose for moderately depressed outpatients is also 225 mg per day for venlafaxine hydrochloride tablets, more severely depressed inpatients in one study of the development program for that product responded to a mean dose of 350 mg per day (range of 150 to 375 mg per day). Whether or not higher doses of venlafaxine hydrochloride extended-release capsules are needed for more severely depressed patients is unknown; however, the experience with venlafaxine hydrochloride extended-release capsules doses higher than 225 mg per day is very limited. 2.3 Social Anxiety Disorder (Social Phobia) The recommended dose is 75 mg per day, administered in a single dose. There was no evidence that higher doses confer any additional benefit. 2.4 Panic Disorder The recommended starting dose is 37.5 mg per day of venlafaxine hydrochloride extended-release capsules for 7 days. Patients not responding to 75 mg per day may benefit from dose increases to a maximum of approximately 225 mg per day. Dose increases should be in increments of up to 75 mg per day, as needed, and should be made at intervals of not less than 7 days. 2.5 Switching Patients from Venlafaxine Hydrochloride Tablets Depressed patients who are currently being treated at a therapeutic dose with venlafaxine hydrochloride tablets may be switched to venlafaxine hydrochloride extended-release capsules at the nearest equivalent dose (mg per day), e.g., 37.5 mg venlafaxine twice a day to 75 mg venlafaxine hydrochloride extended-release capsules once daily. However, individual dosage adjustments may be necessary. 2.6 Specific Populations Patients with Hepatic Impairment The total daily dose should be reduced by 50% in patients with mild (Child-Pugh=5 to 6) to moderate (Child-Pugh=7 to 9) hepatic impairment. In patients with severe hepatic impairment (Child-Pugh=10 to 15) or hepatic cirrhosis, it may be necessary to reduce the dose by 50% or more [See Use in Specific Populations (8.7)]. Patients with Renal Impairment The total daily dose should be reduced by 25% to 50% in patients with mild (CLcr= 60 to 89 mL/min) or moderate (CLcr= 30 to 59 mL/min) renal impairment. In patients undergoing hemodialysis or with severe renal impairment (CLcr < 30 mL/min), the total daily dose should be reduced by 50% or more. Because there was much individual variability in clearance between patients with renal impairment, individualization of dosage may be desirable in some patients [see Use in Specific Populations (8.7)]. 2.7 Maintenance Treatment There is no body of evidence available from controlled studies to indicate how long patients with MDD, SAD, or PD should be treated with venlafaxine hydrochloride extended-release capsules. It is generally agreed that acute episodes of MDD require several months or longer of sustained pharmacological therapy beyond response to the acute episode. Venlafaxine hydrochloride extended-release capsules/venlafaxine hydrochloride tablets have demonstrated continuation of response in clinical studies up to 52 weeks, at the same dose at which patients responded during the initial treatment [see Clinical Studies (14.1)]. It is not known whether or not the dose of venlafaxine hydrochloride extended-release capsules needed for maintenance treatment is identical to the dose needed to achieve an initial response. Patients should be periodically reassessed to determine the need for maintenance treatment and the appropriate dose for such treatment. In patients with SAD, venlafaxine hydrochloride extended-release capsules have been shown to be effective in 6-month clinical studies. The need for continuing medication in patients with SAD who improve with venlafaxine hydrochloride extended-release capsules treatment should be periodically reassessed. In a clinical study for PD, patients continuing venlafaxine hydrochloride extended-release capsules at the same dose at which they responded during the initial 12 weeks of treatment experienced a statistically significantly longer time to relapse than patients randomized to placebo [see Clinical Studies (14.4)]. The need for continuing medication in patients with PD who improve with venlafaxine hydrochloride extended-release capsules treatment should be periodically reassessed. 2.8 Discontinuing Venlafaxine Hydrochloride Extended-release Capsules A gradual reduction in the dose, rather than abrupt cessation, is recommended whenever possible. In clinical studies with venlafaxine hydrochloride extended-release capsules, tapering was achieved by reducing the daily dose by 75 mg at one-week intervals. Individualization of tapering may be necessary [see Warnings and Precautions (5.7)]. 2.9 Switching Patients to or from a Monoamine Oxidase Inhibitor (MAOI) Intended to Treat Psychiatric Disorders At least 14 days should elapse between discontinuation of an MAOI (intended to treat psychiatric disorders) and initiation of therapy with venlafaxine hydrochloride extended-release capsules. In addition, at least 7 days should be allowed after stopping venlafaxine hydrochloride extended-release capsules before starting an MAOI intended to treat psychiatric disorders [see Contraindications (4.2), Warnings and Precautions (5.2), and Drug Interactions (7.2)]. Use of Venlafaxine Hydrochloride Extended-release Capsules with other MAOIs such as Linezolid or Intravenous Methylene Blue Do not start venlafaxine hydrochloride extended-release capsules in a patient who is being treated with linezolid or intravenous methylene blue, because there is an increased risk of serotonin syndrome. In a patient who requires more urgent treatment of a psychiatric condition, other interventions, including hospitalization should be considered [see Contraindications 4.2)]. In some cases, a patient already receiving venlafaxine hydrochloride extended-release capsules therapy may require urgent treatment with linezolid or intravenous methylene blue. If acceptable alternatives to linezolid or intravenous methylene blue are not available and the potential benefits of linezolid or intravenous methylene blue treatment are judged to outweigh the risks of serotonin syndrome in a particular patient, venlafaxine hydrochloride extended-release capsules should be stopped promptly, and linezolid or intravenous methylene blue can be administered. Monitor the patient for symptoms of serotonin syndrome for 7 days or until 24 hours after the last dose of linezolid or intravenous methylene blue, whichever comes first. Therapy with venlafaxine hydrochloride extended-release capsules can be resumed 24 hours after the last dose of linezolid or intravenous methylene blue [see Warnings and Precautions (5.2)]. The risk of administering methylene blue by non-intravenous routes (such as oral tablets or by local injection) or in intravenous doses much lower than 1 mg/kg concomitantly with venlafaxine hydrochloride extended-release capsules are unclear. The clinician should, nevertheless, be aware of the possibility of emergent symptoms of serotonin syndrome with such use [see Warnings and Precautions (5.2)].

INDICATIONS & USAGE SECTION 1.1 Major Depressive Disorder Venlafaxine hydrochloride extended-release capsules, USP are indicated for the treatment of major depressive disorder (MDD). Efficacy was established in three short-term (4, 8, and 12 weeks) and two long-term, maintenance trials. 1.3 Social Anxiety Disorder Venlafaxine hydrochloride extended-release capsules, USP are indicated for the treatment of Social Anxiety Disorder (SAD), also known as social phobia. Efficacy was established in four 12-week and one 26-week, placebo-controlled trials. 1.4 Panic Disorder Venlafaxine hydrochloride extended-release capsules, USP are indicated for the treatment of Panic Disorder (PD), with or without agoraphobia. Efficacy was established in two 12-week placebo-controlled trials.

DRUG ABUSE AND DEPENDENCE SECTION 9.1 Controlled Substance Venlafaxine hydrochloride extended-release capsule is not a controlled substance. 9.2 Abuse While venlafaxine has not been systematically studied in clinical studies for its potential for abuse, there was no indication of drug-seeking behavior in the clinical studies. 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 behavior). 9.3 Dependence In vitro studies revealed that venlafaxine has virtually no affinity for opiate, benzodiazepine, phencyclidine (PCP), or N-methyl-D-aspartic acid (NMDA) receptors. Venlafaxine was not found to have any significant CNS stimulant activity in rodents. In primate drug discrimination studies, venlafaxine showed no significant stimulant or depressant abuse liability. Discontinuation effects have been reported in patients receiving venlafaxine [see Dosage and Administration ( 2.8 )].

OVERDOSAGE SECTION 10.1 Human Experience During the premarketing evaluations of venlafaxine hydrochloride extended-release capsules (for MDD, SAD, and PD) and venlafaxine hydrochloride tablets (for MDD), there were twenty reports of acute overdosage with venlafaxine hydrochloride (6 and 14 reports in venlafaxine hydrochloride extended-release capsules and venlafaxine hydrochloride tablets patients, respectively), either alone or in combination with other drugs and/or alcohol. Somnolence was the most commonly reported symptom. Among the other reported symptoms were paresthesia of all four limbs, moderate dizziness, nausea, numb hands and feet, and hot-cold spells 5 days after the overdose. In most cases, no signs or symptoms were associated with overdose. The majority of the reports involved ingestion in which the total dose of venlafaxine taken was estimated to be no more than several-fold higher than the usual therapeutic dose. One patient who ingested 2.75 g of venlafaxine was observed to have two generalized convulsions and a prolongation of QTc to 500 msec, compared with 405 msec at baseline. Mild sinus tachycardia was reported in two of the other patients. Actions taken to treat the overdose included no treatment, hospitalization and symptomatic treatment, and hospitalization plus treatment with activated charcoal. All patients recovered. In postmarketing experience, overdose with venlafaxine has occurred predominantly in combination with alcohol and/or other drugs. The most commonly reported events in overdosage include tachycardia, changes in level of consciousness (ranging from somnolence to coma), mydriasis, seizures, and vomiting. Electrocardiogram changes (e.g., prolongation of QT interval, bundle branch block, QRS prolongation), ventricular tachycardia, bradycardia, hypotension, rhabdomyolysis, vertigo, liver necrosis, serotonin syndrome, and death have been reported. Published retrospective studies report that venlafaxine overdosage may be associated with an increased risk of fatal outcomes compared to that observed with SSRI antidepressant products, but lower than that for tricyclic antidepressants. Epidemiological studies have shown that venlafaxine-treated patients have a higher preexisting burden of suicide risk factors than SSRI-treated patients. The extent to which the finding of an increased risk of fatal outcomes can be attributed to the toxicity of venlafaxine in overdosage, as opposed to some characteristic(s) of venlafaxine-treated patients, is not clear. Prescriptions for venlafaxine hydrochloride extended-release capsules should be written for the smallest quantity of capsules consistent with good patient management, in order to reduce the risk of overdose. 10.2 Management of Overdosage Consult a Certified Poison Control Center for up-to-date guidance and advice (1-800-222-1222 or www.poison.org). In case of an overdose, provide supportive care, including close medical supervision and monitoring. Treatment should consist of those general measures employed in the management of overdosage with any drug. Consider the possibility of multiple drug overdose. Ensure an adequate airway, oxygenation, and ventilation. Monitor cardiac rhythm and vital signs. Provide supportive and symptomatic measures.

DRUG INTERACTIONS SECTION 7.1 Central Nervous System (CNS)-Active Drugs The risk of using venlafaxine in combination with other CNS-active drugs has not been systematically evaluated. Consequently, caution is advised when venlafaxine hydrochloride extended-release capsules are taken in combination with other CNS- active drugs. 7.2 Monoamine Oxidase Inhibitors Adverse reactions, some of which were serious, have been reported in patients who have recently been discontinued from an MAOI and started on antidepressants with pharmacological properties similar to venlafaxine hydrochloride extended-release capsules (SNRIs or SSRIs), or who have recently had SNRI or SSRI therapy discontinued prior to initiation of an MAOI [see Dosage and Administration (2.9), Contraindications (4.2) and Warnings and Precautions (5.2)]. 7.3 Serotonergic Drugs Based on the mechanism of action of venlafaxine hydrochloride extended-release capsules and the potential for serotonin syndrome, caution is advised when venlafaxine hydrochloride extended-release capsules are coadministered with other drugs that may affect the serotonergic neurotransmitter systems, such as triptans, SSRIs, other SNRIs, linezolid (an antibiotic which is a reversible non-selective MAOI), lithium, tramadol, or St. John's wort. If concomitant treatment with venlafaxine hydrochloride extended-release capsules and these drugs is clinically warranted, careful observation of the patient is advised, particularly during treatment initiation and dose increases. The concomitant use of venlafaxine hydrochloride extended-release capsules with tryptophan supplements is not recommended [see Dosage and Administration (2.9), Contraindications (4.2), and Warnings and Precautions (5.2)]. 7.4 Drugs that Interfere with Hemostasis (e.g., NSAIDs, Aspirin, and Warfarin) Serotonin release by platelets plays an important role in hemostasis. The use of psychotropic drugs that interfere with serotonin reuptake is associated with the occurrence of upper gastrointestinal bleeding and concurrent use of an NSAID or aspirin may potentiate this risk of bleeding [see Warnings and Precautions (5.4)]. Altered anticoagulant effects, including increased bleeding, have been reported when SSRIs and SNRIs are coadministered with warfarin. Patients receiving warfarin therapy should be carefully monitored when venlafaxine hydrochloride extended-release capsules are initiated or discontinued. 7.5 Weight Loss Agents The safety and efficacy of venlafaxine therapy in combination with weight loss agents, including phentermine, have not been established. Coadministration of venlafaxine hydrochloride extended-release capsules and weight loss agents is not recommended. Venlafaxine hydrochloride extended-release capsules are not indicated for weight loss alone or in combination with other products. 7.6 Effects of Other Drugs on Venlafaxine Hydrochloride Extended-release Capsules Figure 1: Effect of interacting drugs on the pharmacokinetics of venlafaxine and active metabolite Venlafaxine hydrochloride extended-release capsules, USP Abbreviations: ODV, O-desmethylvenlafaxine; AUC, area under the curve; Cmax, peak plasma concentrations; EM's, extensive metabolizers; PM's, poor metabolizers * No dose adjustment on coadministration with CYP2D6 inhibitors (Fig 3 and Metabolism Section 12.3) 7.7 Effects of Venlafaxine Hydrochloride Extended-release Capsules on Other Drugs Figure 2: Effect of venlafaxine on the pharmacokinetics interacting drugs and their active metabolites.

Note: *: Administration of venlafaxine in a stable regimen did not exaggerate the psychomotor and psychometric effects induced by ethanol in these same subjects when they were not receiving venlafaxine. 7.8 Drug-Laboratory Test Interactions False-positive urine immunoassay screening tests for phencyclidine (PCP) and amphetamine have been reported in patients taking venlafaxine. This is due to lack of specificity of the screening tests. False positive test results may be expected for several days following discontinuation of venlafaxine therapy. Confirmatory tests, such as gas chromatography/mass spectrometry, will distinguish venlafaxine from PCP and amphetamine.

CLINICAL PHARMACOLOGY SECTION 12.1 Mechanism of Action The exact mechanism of the antidepressant action of venlafaxine in humans is unknown, but is thought to be related to the potentiation of serotonin and norepinephrine in the central nervous system, through inhibition of their reuptake. Non- clinical studies have demonstrated that venlafaxine and its active metabolite, ODV, are potent and selective inhibitors of neuronal serotonin and norepinephrine reuptake and weak inhibitors of dopamine reuptake. 12.2 Pharmacodynamics Venlafaxine and ODV have no significant affinity for muscarinic-cholinergic, H1-histaminergic, or α1 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. 12.3 Pharmacokinetics Steady-state concentrations of venlafaxine and ODV in plasma are attained within 3 days of oral multiple- dose therapy. Venlafaxine and ODV exhibited linear kinetics over the dose range of 75 to 450 mg per day. Mean±SD steady-state plasma clearance of venlafaxine and ODV is 1.3±0.6 and 0.4±0.2 L/h/kg, respectively; apparent elimination half-life is 5±2 and 11±2 hours, respectively; and apparent (steady state) volume of distribution is 7.5±3.7 and 5.7±1.8 L/kg, respectively. Venlafaxine and ODV are minimally bound at therapeutic concentrations to plasma proteins (27% and 30%, respectively). Absorption and Distribution Venlafaxine is well absorbed and extensively metabolized in the liver. ODV is the major active metabolite. On the basis of mass balance studies, at least 92% of a single oral dose of venlafaxine is absorbed. The absolute bioavailability of venlafaxine is approximately 45%. Administration of venlafaxine hydrochloride extended-release capsules (150 mg once daily) generally resulted in lower Cmax and later Tmax values than for venlafaxine hydrochloride tablets administered twice daily (Table 16). When equal daily doses of venlafaxine were administered as either an immediate-release tablet or the extended-release capsule, the exposure to both venlafaxine and ODV was similar for the two treatments, and the fluctuation in plasma concentrations was slightly lower with the venlafaxine hydrochloride extended-release capsules. Therefore, venlafaxine hydrochloride extended-release capsules provide a slower rate of absorption, but the same extent of absorption compared with the immediate-release tablet. Table 16Comparison of Cmax and Tmax Values for Venlafaxine and ODV Following OralAdministration of Venlafaxine Hydrochloride Extended-release Capsules and Venlafaxine Hydrochloride Tablets Venlafaxine ODV Cmax (ng/mL) Tmax (h) Cmax (ng/mL) Tmax (h) Venlafaxine Hydrochloride Extended-release Capsules (150 mg once daily) 150 5.5 260 9 Venlafaxine Hydrochloride Tablets (75 mg twice daily) 225 2 290 3 Food did not affect the bioavailability of venlafaxine or its active metabolite, ODV. Time of administration (AM versus PM) did not affect the pharmacokinetics of venlafaxine and ODV from the 75 mg venlafaxine hydrochloride extended-release capsules. Venlafaxine is not highly bound to plasma proteins; therefore, administration of venlafaxine hydrochloride extended-release capsules to a patient taking another drug that is highly protein-bound should not cause increased free concentrations of the other drug. Metabolism and Elimination Following absorption, venlafaxine undergoes extensive presystemic metabolism in the liver, primarily to ODV, but also to N-desmethylvenlafaxine, N,O-didesmethylvenlafaxine, and other minor metabolites. In vitro studies indicate that the formation of ODV is catalyzed by CYP2D6; this has been confirmed in a clinical study showing that patients with low CYP2D6 levels (poor metabolizers) had increased levels of venlafaxine and reduced levels of ODV compared to people with normal CYP2D6 levels (extensive metabolizers) [see Use in Specific Populations (8.7)]. Approximately 87% of a venlafaxine dose is recovered in the urine within 48 hours as unchanged venlafaxine (5%), unconjugated ODV (29%), conjugated ODV (26%), or other minor inactive metabolites (27%). Renal elimination of venlafaxine and its metabolites is thus the primary route of excretion.

NONCLINICAL TOXICOLOGY SECTION 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Tumors were not increased by venlafaxine treatment in mice or rats. Venlafaxine was given by oral gavage to mice for 18 months at doses up to 120 mg/kg per day, which was 1.7 times the maximum recommended human dose on a mg/m2 basis. Venlafaxine was also given to rats by oral gavage for 24 months at doses up to 120 mg/kg per day. In rats receiving the 120 mg/kg dose, plasma concentrations of venlafaxine at necropsy were 1 times (male rats) and 6 times (female rats) the plasma concentrations of patients receiving the maximum recommended human dose. Plasma levels of the O-desmethyl metabolite (ODV) were lower in rats than in patients receiving the maximum recommended dose. O desmethylvenlafaxine (ODV), the major human metabolite of venlafaxine, administered by oral gavage to mice and rats for 2 years did not increase the incidence of tumors in either study. Mice received ODV at dosages up to 500/300 mg/kg/day (dosage lowered after 45 weeks of dosing). The exposure at the 300 mg/kg/day dose is 9 times that of a human dose of 225 mg/day. Rats received ODV at dosages up to 300 mg/kg/day (males) or 500 mg/kg/day (females). The exposure at the highest dose is approximately 8 (males) or 11 (females) times that of a human dose of 225 mg/day. Mutagenesis Venlafaxine and the major human metabolite, ODV, were not mutagenic in the Ames reverse mutation assay in Salmonella bacteria or the Chinese hamster ovary/HGPRT mammalian cell forward gene mutation assay. Venlafaxine was also not mutagenic or clastogenic in the in vitro BALB/c-3T3 mouse cell transformation assay, the sister chromatid exchange assay in cultured Chinese hamster ovary cells, or in the in vivo chromosomal aberration assay in rat bone marrow. ODV was not clastogenic in the in vitro Chinese hamster ovary cell chromosomal aberration assay or in the in vivo chromosomal aberration assay in rats. Impairment of Fertility Reproduction and fertility studies of venlafaxine in rats showed no adverse effects of venlafaxine on male or female fertility at oral doses of up to 2 times the maximum recommended human dose of 225 mg/day on a mg/m2 basis. However, reduced fertility was observed in a study in which male and female rats were treated with O-desmethylvenlafaxine (ODV), the major human metabolite of venlafaxine, prior to and during mating and gestation. This occurred at an ODV exposure (AUC) approximately 2 to 3 times that associated with a human venlafaxine dose of 225 mg/day.

INFORMATION FOR PATIENTS SECTION See FDA-approved patient labeling (Medication Guide). Prescribers or other healthcare professionals should inform patients, their families, and their caregivers about the benefits and risks associated with treatment with venlafaxine hydrochloride extended-release capsules and should counsel them in its appropriate use. A patient Medication Guide about "Antidepressant Medicines, Depression and Other Serious Mental Illnesses, and Suicidal Thoughts or Actions" is available for venlafaxine hydrochloride extended-release capsules. The prescriber or healthcare professional should instruct patients, their families, and their caregivers to read the Medication Guide and should assist them in understanding its contents. Patients should be given the opportunity to discuss the contents of the Medication Guide and to obtain answers to any questions they may have. The complete text of the Medication Guide is reprinted at the end of this document. Patients should be advised of the following issues and should be asked to alert their prescriber if these occur while taking venlafaxine hydrochloride extended-release capsules. Suicidal Thoughts and Behaviors Advise patients, their families and caregivers to look for the emergence of suicidality, worsening of depression, and other psychiatric symptoms (anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia, psychomotor restlessness, hypomania, mania, other unusual changes in behavior), especially early during treatment and when the dose is adjusted up or down. Such symptoms should be reported to the patient's prescriber or health professional, especially if they are severe, abrupt in onset, or were not part of the patient's presenting symptoms. Symptoms such as these may be associated with an increased risk for suicidal thinking and behavior and indicate a need for very close monitoring [see Boxed Warning and Warnings and Precautions ( 5.1 )]. Concomitant Medication Advise patients taking venlafaxine hydrochloride extended-release capsules not to use concomitantly other products containing venlafaxine or desvenlafaxine. Healthcare professionals should instruct patients not to take venlafaxine hydrochloride extended-release capsules with an MAOI or within 14 days of stopping an MAOI and to allow 7 days after stopping venlafaxine hydrochloride extended-release capsules before starting an MAOI [see Contraindications ( 4.2 )]. Serotonin Syndrome Patients should be cautioned about the risk of serotonin syndrome, with the concomitant use of venlafaxine hydrochloride extended-release capsules and triptans, tramadol, tryptophan supplements, with antipsychotics or other dopamine antagonists, or other serotonergic agents [see Warnings and Precautions ( 5.2 ) and Drug Interactions ( 7.3 )]. Elevated Blood Pressure Advise patients that they should have regular monitoring of blood pressure when taking venlafaxine hydrochloride extended-release capsules [see Warnings and Precautions ( 5.3 )]. Abnormal Bleeding Patients should be cautioned about the concomitant use of venlafaxine hydrochloride extended-release capsules and NSAIDs, aspirin, warfarin, or other drugs that affect coagulation since combined use of psychotropic drugs that interfere with serotonin reuptake and these agents has been associated with an increased risk of bleeding [see Warnings and Precautions ( 5.4 )]. Angle Closure Glaucoma Patients should be advised that taking venlafaxine hydrochloride extended-release capsules can cause mild pupillary dilation, which in susceptible individuals, can lead to an episode of angle closure glaucoma. Preexisting glaucoma is almost always open-angle glaucoma because angle closure glaucoma, when diagnosed, can be treated definitively with iridectomy. Open-angle glaucoma is not a risk factor for angle closure glaucoma. Patients may wish to be examined to determine whether they are susceptible to angle closure, and have a prophylactic procedure (e.g., iridectomy), if they are susceptible [see Warnings and Precautions ( 5.5 )]. Activation of Mania/Hypomania Advise patients, their families and caregivers to observe for signs of activation of mania/hypomania [see Warnings and Precautions ( 5.6 )]. Cardiovascular/Cerebrovascular Disease Caution is advised in administering venlafaxine hydrochloride extended-release capsules to patients with cardiovascular, cerebrovascular, or lipid metabolism disorders [see Adverse Reactions ( 6.1 )]. Serum Cholesterol and Triglyceride Elevation Advise patients that elevations in total cholesterol, LDL and triglycerides may occur and that measurement of serum lipids may be considered [see Warnings and Precautions ( 6.3 )]. Discontinuation [Symptoms] Advise patients not to stop taking venlafaxine hydrochloride extended-release capsules without talking first with their healthcare professional. Patients should be aware that discontinuation effects may occur when stopping venlafaxine hydrochloride extended-release capsules [see Warnings and Precautions ( 5.7 ) and Adverse Reactions ( 6.1 )]. Interference with Cognitive and Motor Performance Caution patients about operating hazardous machinery, including automobiles, until they are reasonably certain that venlafaxine hydrochloride extended-release capsules therapy does not adversely affect their ability to engage in such activities. Alcohol Advise patients to avoid alcohol while taking venlafaxine hydrochloride extended-release capsules [see Drug Interactions ( 7.6 )]. Allergic Reactions Advise patients to notify their physician if they develop allergic phenomena such as rash, hives, swelling, or difficulty breathing. Pregnancy Advise patients to notify their physician if they become pregnant or intend to become pregnant during therapy [see Use in Specific Populations ( 8.1 )]. Nursing Advise patients to notify their physician if they are breast-feeding an infant [see Use in Specific Populations ( 8.3 )]. Residual Spheroids Venlafaxine hydrochloride extended-release capsule contains spheroids, which release the drug slowly into the digestive tract. The insoluble portion of these spheroids is eliminated, and patients may notice spheroids passing in the stool or via colostomy. Patients should be informed that the active medication has already been absorbed by the time the patient sees the spheroids.

CLINICAL STUDIES SECTION 14.1 Major Depressive Disorder The efficacy of venlafaxine hydrochloride extended-release capsules as a treatment for Major Depressive Disorder (MDD) was established in two placebo-controlled, short-term (8 weeks for study 1; 12 weeks for study 2), flexible-dose studies, with doses starting at 75 mg per day and ranging to 225 mg per day in adult outpatients meeting DSM-III-R or DSM-IV criteria for MDD. In moderately depressed outpatients, the initial dose of venlafaxine was 75 mg per day. In both studies, venlafaxine hydrochloride extended-release capsules demonstrated superiority over placebo on the primary efficacy measure defined as change from baseline in the HAM-D-21 total score to the endpoint visit, venlafaxine hydrochloride extended-release capsules also demonstrated superiority over placebo on the key secondary efficacy endpoint, the Clinical Global Impressions (CGI) Severity of Illness scale. Examination of gender subsets of the population studied did not reveal any differential responsiveness on the basis of gender. A 4-week study of inpatients meeting DSM-III-R criteria for MDD with melancholia utilizing venlafaxine hydrochloride tablets in a range of 150 to 375 mg per day (divided in a three-times-a-day schedule) demonstrated superiority of venlafaxine hydrochloride tablets over placebo based on the HAM-D-21 total score. The mean dose in completers was 350 mg per day (study 3). In a longer-term study, adult outpatients with MDD who had responded during an 8-week open-label study on venlafaxine hydrochloride extended-release capsules (75, 150, or 225 mg, once daily every morning) were randomized to continuation of their same venlafaxine hydrochloride extended-release capsules dose or to placebo, for up to 26 weeks of observation for relapse. Response during the open-label phase was defined as a CGI Severity of Illness item score of ≤3 and a HAM-D-21 total score of ≤10 at the day 56 evaluation. Relapse during the double-blind phase was defined as follows: (1) a reappearance of major depressive disorder as defined by DSM-IV criteria and a CGI Severity of Illness item score of ≥4 (moderately ill), (2) 2 consecutive CGI Severity of Illness item scores of ≥4, or (3) a final CGI Severity of Illness item score of ≥4 for any patient who withdrew from the study for any reason. Patients receiving continued venlafaxine hydrochloride extended-release capsules treatment experienced statistically significantly lower relapse rates over the subsequent 26 weeks compared with those receiving placebo (study 4). In a second longer term trial, adult outpatients with MDD, recurrent type, who had responded (HAM-D 21 total score ≤ 12 at the day 56 evaluation) and continued to be improved [defined as the following criteria being met for days 56 through 180: (1) no HAM-D-21 total score ≥ 20; (2) no more than 2 HAM D-21 total scores > 10, and (3) no single CGI Severity of Illness item score ≥ 4 (moderately ill)] during an initial 26 weeks of treatment on venlafaxine hydrochloride tablets [100 to 200 mg per day, on a twice daily schedule] were randomized to continuation of their same venlafaxine hydrochloride tablets dose or to placebo. The follow-up period to observe patients for relapse, defined as a CGI Severity of Illness item score ≥ 4, was for up to 52 weeks. Patients receiving continued venlafaxine hydrochloride tablets treatment experienced statistically significantly lower relapse rates over the subsequent 52 weeks compared with those receiving placebo (study 5).

In these five studies, venlafaxine hydrochloride extended-release capsule was statistically significantly more effective than placebo on change from baseline to endpoint on the Liebowitz Social Anxiety Scale (LSAS) total score. There was no evidence for any greater effectiveness of the 150 to 225 mg per day group compared to the 75 mg per day group in the 6-month study. Examination of subsets of the population studied did not reveal any differential responsiveness on the basis of gender. There was insufficient information to determine the effect of age or race on outcome in these studies.

Patients received fixed doses of 75 or 150 mg per day in one study (study 1) and 75 or 225 mg per day in the other study (study 2). Efficacy was assessed on the basis of outcomes in three variables: (1) percentage of patients free of full- symptom panic attacks on the Panic and Anticipatory Anxiety Scale (PAAS); (2) mean change from baseline to endpoint on the Panic Disorder Severity Scale (PDSS) total score; and (3) percentage of patients rated as responders (much improved or very much improved) on the Clinical Global Impressions (CGI) Improvement scale. In these two studies, venlafaxine hydrochloride extended-release capsule was statistically significantly more effective than placebo (for each fixed dose) on all three endpoints, but a dose-response relationship was not clearly established. Examination of subsets of the population studied did not reveal any differential responsiveness on the basis of gender. There was insufficient information to determine the effect of age or race on outcome in these studies. In a longer term study (study 3), adult outpatients meeting DSM-IV criteria for PD who had responded during a 12-week open phase with venlafaxine hydrochloride extended-release capsules (75 to 225 mg per day) were randomly assigned to continue the same venlafaxine hydrochloride extended-release capsules dose (75, 150, or 225 mg) or switch to placebo for observation for relapse under double-blind conditions. Response during the open phase was defined as ≤ 1 full-symptom panic attack per week during the last 2 weeks of the open phase and a CGI Improvement score of 1 (very much improved) or 2 (much improved). Relapse during the double-blind phase was defined as having 2 or more full-symptom panic attacks per week for 2 consecutive weeks or having discontinued due to loss of effectiveness as determined by the investigators during the study. Randomized patients were in response status for a mean time of 34 days prior to being randomized. In the randomized phase following the 12 week open-label period, patients receiving continued venlafaxine hydrochloride extended-release capsules experienced a statistically significantly longer time to relapse.

USE IN SPECIFIC POPULATIONS SECTION 8.1 Pregnancy Teratogenic Effects – Pregnancy Category C Venlafaxine did not cause malformations in offspring of rats or rabbits given doses up to 2.5 times (rat) or 4 times (rabbit) the maximum recommended human daily dose on a mg/m2 basis. However, in rats, there was a decrease in pup weight, an increase in stillborn pups, and an increase in pup deaths during the first 5 days of lactation, when dosing began during pregnancy and continued until weaning. The cause of these deaths is not known. These effects occurred at 2.5 times (mg/m2) the maximum human daily dose. The no effect dose for rat pup mortality was 0.25 times the human dose on a mg/m2 basis. In reproductive developmental studies in rats and rabbits with O-desmethylvenlafaxine (ODV), the major human metabolite of venlafaxine, evidence of teratogenicity was not observed at exposure margins of 13 in rats and 0.3 in rabbits. There are no adequate and well-controlled studies in pregnant women. Venlafaxine hydrochloride extended-release capsules should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Non-teratogenic Effects Neonates exposed to venlafaxine hydrochloride extended-release capsules, other SNRIs, or SSRIs, late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding. Such complications can arise immediately upon delivery. Reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying. These features are consistent with either a direct toxic effect of SSRIs and SNRIs, or possibly a drug discontinuation syndrome. It should be noted, that in some cases the clinical picture is consistent with serotonin syndrome [see Warnings and Precautions ( 5.2 ) and Drug Interactions ( 7.3 )]. When treating a pregnant woman with venlafaxine hydrochloride extended-release capsules during the third trimester, the physician should carefully consider the potential risks and benefits of treatment. 8.2 Labor and Delivery The effect of venlafaxine on labor and delivery in humans is unknown. 8.3 Nursing Mothers Venlafaxine and ODV have been reported to be excreted in human milk. Because of the potential for serious adverse reactions in nursing infants from venlafaxine hydrochloride extended-release capsules, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. 8.4 Pediatric Use Two placebo-controlled trials in 766 pediatric patients with MDD have been conducted with venlafaxine hydrochloride extended-release capsules, and the data were not sufficient to support a claim for use in pediatric patients. Anyone considering the use of venlafaxine hydrochloride extended-release capsules in a child or adolescent must balance the potential risks with the clinical need [see Boxed Warning , Warnings and Precautions ( 5.1 , 5.10 , 5.11 ) and Adverse Reactions ( 6.4 )]. Although no studies have been designed to primarily assess venlafaxine hydrochloride extended-release capsule's impact on the growth, development, and maturation of children and adolescents, the studies that have been done suggest that venlafaxine hydrochloride extended-release capsules may adversely affect weight and height (see Warnings and Precautions ( 5.10 )). Should the decision be made to treat a pediatric patient with venlafaxine hydrochloride extended-release capsules, regular monitoring of weight and height is recommended during treatment, particularly if treatment is to be continued long-term [see Warnings and Precautions ( 5.10 , 5.11 )]. The safety of venlafaxine hydrochloride extended-release capsules treatment for pediatric patients has not been systematically assessed for chronic treatment longer than six months in duration. In the studies conducted in pediatric patients (ages 6 to 17), the occurrence of blood pressure and cholesterol increases considered to be clinically relevant in pediatric patients was similar to that observed in adult patients. Consequently, the precautions for adults apply to pediatric patients [see Warnings and Precautions ( 5.3 , 6.3 )]. 8.5 Geriatric Use The percentage of patients in clinical studies for venlafaxine hydrochloride extended-release capsules for MDD, SAD, and PD who were 65 years of age or older are shown in Table 15. Table 15Percentage (and Number of Patients Studied) of Patients 65 Years of Age and Older by Indicationa aIn addition, in the premarketing assessment of venlafaxine hydrochloride tablets, 12% (357/2,897) of patients were ≥ 65 years of age. Indication Venlafaxine Hydrochloride Extended-release Capsules MDD 4 (14/357) SAD 1 (10/819) PD 2 (16/1,001) No overall differences in effectiveness or safety were observed between geriatric patients and younger patients, and other reported clinical experience generally has not identified differences in response between the elderly and younger patients. However, greater sensitivity of some older individuals cannot be ruled out. SSRIs and SNRIs, including venlafaxine hydrochloride extended-release capsules, have been associated with cases of clinically significant hyponatremia in elderly patients, who may be at greater risk for this adverse event [see Warnings and Precautions ( 5.9 )]. The pharmacokinetics of venlafaxine and ODV are not substantially altered in the elderly [see Clinical Pharmacology ( 12.3 ) and (see Figure 3)]. No dose adjustment is recommended for the elderly on the basis of age alone, although other clinical circumstances, some of which may be more common in the elderly, such as renal or hepatic impairment, may warrant a dose reduction [see Dosage and Administration ( 2.6 )]. 8.6 Age and Gender A population pharmacokinetic analysis of 404 venlafaxine hydrochloride tablets-treated patients from two studies involving both twice daily and three times daily regimens showed that dose-normalized trough plasma levels of either venlafaxine or ODV were unaltered by age or gender differences. Dosage adjustment based on the age or gender of a patient is generally not necessary [see Dosage and Administration ( 2.6 )] (see Table 15). 8.7 Use in Patient Subgroups Figure 3: Pharmacokinetics of venlafaxine and its metabolite O-desmethylvenlafaxine (ODV) in special populations. Abbreviations: ODV, O-desmethylvenlafaxine; AUC, area under the curve; Cmax, peak plasma concentrations; *Similar effect is expected with strong CYP2D6 inhibitors

BOXED WARNING SECTION WARNING: SUICIDAL THOUGHTS AND BEHAVIORS Antidepressants increased the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term studies. These studies did not show an increase in the risk of suicidal thoughts and behavior with antidepressant use in patients over age 24; there was a reduction in risk with antidepressant use in patients aged 65 and older [see Warnings and Precautions (5.1)]. In patients of all ages who are started on antidepressant therapy monitor closely for clinical worsening and emergence of suicidal thoughts and behaviors. Advise families and caregivers of the need for close observation and communication with the prescriber [see Warnings and Precautions (5.1) and Patient Counseling Information (17)].
