Capsules should be taken whole; do not divide, crush, chew, or dissolve ( 2.1 ). When discontinuing treatment, reduce the dose gradually ( 2.10 , 5.7 ). Renal impairment: reduce the total daily dose by 25% to 50% in patients with renal impairment. Reduce the total daily dose by 50% or more in patients undergoing dialysis or with severe renal impairment ( 2.9 ). Hepatic impairment: reduce the daily dose by 50% in patients with mild to moderate hepatic impairment. In patients with severe hepatic impairment or hepatic cirrhosis, it may be necessary to reduce the dose by more than 50% ( 2.8 ). 2.1 General Administration Information Administer venlafaxine hydrochloride extended-release capsules as 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) ] . Swallow capsules whole with fluid. Do not divide, crush, chew, or place in water. The capsule may also 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). 2.2 Major Depressive Disorder For most patients, the recommended starting dose for venlafaxine hydrochloride extended-release capsules is 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. In the clinical studies establishing efficacy, upward titration was permitted at intervals of 2 weeks or more. 2.3 Generalized Anxiety Disorder For most patients, the recommended starting dose for venlafaxine hydrochloride extended-release capsules is 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. 2.4 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. 2.5 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. 2.6 Screen for Bipolar Disorder Prior to Starting Venlafaxine Hydrochloride Extended-Release Capsules Prior to initiating treatment with venlafaxine hydrochloride extended-release capsules, screen patients for a personal or family history of bipolar disorder, mania, or hypomania [see Warnings and Precautions (5.6) ] . 2.7 Switching Patients from Venlafaxine Hydrochloride Tablets Patients with depression who are currently being treated with Effexor may be switched to venlafaxine hydrochloride extended-release capsules at the nearest equivalent dose (mg per day), e.g., 37.5 mg venl…

Warnings

5 WARNINGS AND PRECAUTIONS Serotonin Syndrome : Increased risk when co-administered with other serotonergic agents, but also when taken alone. If it occurs, discontinue venlafaxine hydrochloride extended-release capsules and serotonergic agents and initiate supportive treatment ( 4 , 5.2 , 7.1 ). Elevated Blood Pressure : Control hypertension before initiating treatment. Monitor blood pressure regularly during treatment ( 5.3 ). Increased Risk of Bleeding : Concomitant use of aspirin, NSAIDs, other antiplatelet drugs, warfarin, and other anticoagulants may increase risk ( 5.4 ). Angle-Closure Glaucoma : Angle-closure glaucoma has occurred in patients with untreated anatomically narrow angles, treated with antidepressants ( 5.5 ). Activation of Mania or Hypomania : Screen patients for bipolar disorder ( 5.6 ). Discontinuation Syndrome : Taper dose and monitor for discontinuation symptoms ( 5.7 ). Seizures: Can occur. Use cautiously in patients with seizure disorder ( 5.8 ). Hyponatremia : Can occur in association with SIADH ( 5.9 ). Interstitial Lung Disease and Eosinophilic Pneumonia: Can occur ( 5.12 ). Sexual Dysfunction : Venlafaxine hydrochloride extended-release capsules may cause symptoms of sexual dysfunction ( 5.13 ). 5.1 Suicidal Thoughts and Behaviors in Adolescents and Young Adults In pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant classes) that included approximately 77,000 adult patients and 4,500 pediatric patients, the incidence of suicidal thoughts and behaviors in antidepressant-treated patients age 24 years and younger was greater than in placebo-treated patients. There was considerable variation in risk of suicidal thoughts and behaviors among drugs, but there was an increased risk identified in young patients for most drugs studied. There were differences in absolute risk of suicidal thoughts and behaviors across the different indications, with the highest incidence in patients with MDD. The drug-placebo differences in the number of cases of suicidal thoughts and behaviors per 1,000 patients treated are provided in Table 1. Table 1: Risk Differences of the Number of Patients of Suicidal Thoughts and Behaviors in the Pooled Placebo-Controlled Trials of Antidepressants in Pediatric* and Adult Patients Age Range Drug-Placebo Difference in Number of Patients of Suicidal Thoughts and Behaviors per 1,000 Patients Treated Increases Compared to Placebo < 18 years old 14 additional patients 18 to 24 years old 5 additional patients Decreases Compared to Placebo 25 to 64 years old 1 fewer patient ≥ 65 years old 6 fewer patients * Venlafaxine hydrochloride extended-release capsules are not approved in pediatric patients. It is unknown whether the risk of suicidal thoughts and behaviors in children, adolescents, and young adults extends to longer-term use, i.e., beyond four months. However, there is substantial evidence from placebo-controlled maintenance trials in adults with MDD that antidepressants delay the recurrence of depression and that depression itself is a risk factor for suicidal thoughts and behaviors. Monitor all antidepressant-treated patients for any indication for clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of drug therapy, and at times of dosage changes. Counsel family members or caregivers of patients to monitor for changes in behavior and to alert the healthcare provider. Consider changing the therapeutic regimen, including possibly discontinuing venlafaxine hydrochloride extended-release capsules, in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors. 5.2 Serotonin Syndrome Serotonin-norepinephrine reuptake inhibitors (SNRIs), including venlafaxine hydrochloride extended-release capsules, can precipitate serotonin syndrome, apotentially life-threatening condition. The risk is increased with concomitant use of other seroto…

Contraindications

4 CONTRAINDICATIONS Venlafaxine hydrochloride extended-release capsules are contraindicated in patients: with known hypersensitivity to venlafaxine hydrochloride, desvenlafaxine succinate or to any excipients in the formulation [see Adverse Reactions (6.2) ] . taking, or within 14 days of stopping, MAOIs (including the MAOIs linezolid and intravenous methylene blue) because of the risk of serotonin syndrome [see Dosage and Administration (2.11) , Warnings and Precautions (5.2) , and Drug Interactions (7.1) ] . Hypersensitivity to venlafaxine hydrochloride, desvenlafaxine succinate, or any excipients in the venlafaxine hydrochloride extended-release capsules formulation ( 4 ). Concomitant use of monoaminoxidase inhibitors (MAOIs) or within 14 days of discontinuing an MAOI ( 4 , 5.2 , 7.1 ).

Drug interactions

7 DRUG INTERACTIONS 7.1 Drugs Having Clinically Important Interactions with Venlafaxine Hydrochloride Extended-Release Capsules Table 15: Clinically Important Drug Interactions with Venlafaxine Hydrochloride Extended-Release Capsules Monoamine Oxidase Inhibitors (MAOI) Clinical Impact The concomitant use of SNRIs, including venlafaxine hydrochloride extended-release capsules, with MAOIs increases the risk of serotonin syndrome. Intervention Concomitant use of venlafaxine hydrochloride extended-release capsules is contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue [see Dosage and Administration (2.11) , Contraindications (4) and Warnings and Precautions (5.2) ]. Other Serotonergic Drugs Clinical Impact Concomitant use of venlafaxine hydrochloride extended-release capsules with other serotonergic drugs (including other SNRIs, SSRIs, triptans, tricyclic antidepressants, opioids, lithium, buspirone, amphetamines, tryptophan, and St.John's Wort) increases the risk of serotonin syndrome. Intervention Monitor for symptoms of serotonin syndrome when venlafaxine hydrochloride extended-release capsules is used concomitantly with other drugs that may affect the serotonergic neurotransmitter systems. If serotonin syndrome occurs, consider discontinuation of venlafaxine hydrochloride extended-release capsules and/or concomitant serotonergic drugs [see Dosage and Administration (2.11) and Warnings and Precautions (5.2) ]. Drugs that Interfere with Hemostasis Clinical Impact Concomitant use of venlafaxine hydrochloride extended-release capsules with an antiplatelet or anticoagulant drug may potentiate the risk of bleeding. This may be due to the effect of venlafaxine hydrochloride extended-release capsules on the release of serotonin by platelets. Intervention Closely monitor for bleeding for patients receiving an antiplatelet or anticoagulant drug when venlafaxine hydrochloride extended-release capsules is initiated or discontinued [see Warnings and Precautions (5.4) ] . Effect of CYP3A Inhibitors Clinical Impact Concomitant use of a CYP3A inhibitor increases the C max and AUC of venlafaxine and O-desmethylvenlafaxine (ODV) [see Clinical Pharmacology (12.3) ] , which may increase the risk of toxicity of venlafaxine hydrochloride extended-release capsules Intervention Consider reducing the dose of venlafaxine hydrochloride extended-release capsules. CYP2D6 Substrates Clinical Impact Concomitant use of venlafaxine hydrochloride extended-release capsules increases C max and AUC of a CYP2D6 substrate, which may increase the risk of toxicity of the CYP2D6 substrate [see Clinical Pharmacology (12.3) ] . Intervention Consider reduction in dose of concomitant CYP2D6 substrates. 7.2 Other Drug Interactions with Venlafaxine Hydrochloride Extended-Release Capsules Central Nervous System (CNS)-Active Drugs The risk of using venlafaxine concomitantly with other CNS-active drugs (including alcohol) has not been systematically evaluated. Consequently, caution is advised when venlafaxine hydrochloride extended-release capsules are taken concomitantly in combination with other CNS-active drugs. Weight Loss Agents Concomitant use of venlafaxine hydrochloride extended-release capsules and weight loss agents is not recommended. The safety and efficacy of venlafaxine therapy in combination with weight loss agents, including phentermine, have not been established. Venlafaxine hydrochloride extended-release capsules are not indicated for weight loss alone or in combination with other products. Laboratory Test Interference False-positive urine immunoassay screening tests for phencyclidine (PCP) and amphetamine have been reported in patients taking venlafaxine 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 venlafaxin…

Pregnancy

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antidepressants, including venlafaxine hydrochloride extended-release capsules, during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Antidepressants at 1-844-405-6185 or visiting online at https://womensmentalhealth.org/clinical-and-research­programs/pregnancyregistry/antidepressants/ . Risk Summary Based on data from published observational studies, exposure to SNRIs, particularly in the month before delivery, has been associated with a less than 2-fold increase in the risk of postpartum hemorrhage [see Warnings and Precautions (5.4) and Clinical Considerations] . Available data from published epidemiologic studies on venlafaxine use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage or adverse fetal outcomes (see Data) . Available data from observational studies with venlafaxine have identified a potential increased risk for preeclampsia when used during mid to late pregnancy; exposure to SNRIs near delivery may increase the risk for postpartum hemorrhage (see Clinical Considerations) . There are risks associated with untreated depression in pregnancy and poor neonatal adaptation in newborns with exposure to SNRIs, including venlafaxine hydrochloride extended-release capsules, during pregnancy (see Clinical Considerations) . In animal studies, there was no evidence of malformations or fetotoxicity following administration of venlafaxine during organogenesis at doses up to 2.5 times (rat) or 4 times (rabbit) the maximum recommended human daily dose on a mg/m 2 basis. Postnatal mortality and decreased pup weights were observed following venlafaxine administration to pregnant rats during gestation and lactation at 2.5 times (mg/m 2 ) the maximum human daily dose. The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Women who discontinue antidepressants during pregnancy are more likely to experience a relapse of major depression than women who continue antidepressants. This finding is from a prospective, longitudinal study that followed 201 pregnant women with a history of major depression who were euthymic and taking antidepressants at the beginning of pregnancy. Consider the risk of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum. Maternal Adverse Reactions Exposure to venlafaxine in mid to late pregnancy may increase the risk for preeclampsia, and exposure to venlafaxine in the month before delivery may be associated with an increased risk of postpartum hemorrhage [see Warnings and Precautions (5.4) ]. Fetal/Neonatal Adverse Reactions Neonates exposed to SNRIs 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, tremors, jitteriness, irritability, and constant crying. These findings are consistent with either a direct toxic effect of 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) ] . Monitor neonates who were exposed to venlafaxine hydrochloride ext…

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, GAD, 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.
