WARNING: SUICIDAL THOUGHTS AND BEHAVIORS
Antidepressants increased the risk of suicidal thoughts and behavior in pediatric and young adult patients in short-term studies. Closely monitor all antidepressant-treated patients for clinical worsening, and emergence of suicidal thoughts and behaviors [see Warnings and Precautions (5.1 ]. Venlafaxine hydrochloride extended-release capsules are not approved for use in pediatric patients [see Use in Specific Populations (8.4) ].

2 DOSAGE AND ADMINISTRATION
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 capsule 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 capsule 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 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.
2.8 Dosage Recommendations for Patients with Hepatic Impairment
Reduce the venlafaxine hydrochloride extended-release capsules total daily dose by 50% in patients with mild (Child-Pugh Class A) to moderate (Child-Pugh Class B) hepatic impairment. Reduce the total daily dose by 50% or more in patients with severe hepatic impairment (Child-Pugh Class C) or hepatic cirrhosis [see Use in Specific Populations (8.6)] .
2.9 Dosage Recommendations for Patients with Renal Impairment
Reduce the venlafaxine hydrochloride extended-release capsules total daily dose by 25% to 50% in patients with mild (CLcr 60 to 89 mL/min) or moderate (CLcr 30 to 59 mL/min) renal impairment. Reduce the total daily dose by 50% or more in patients undergoing hemodialysis or with severe renal impairment (CLcr < 30 mL/min). Because there was much individual variability in clearance between patients with renal impairment, individualization of dosage is recommended in some patients [see Use in Specific Populations (8.7)] .
2.10 Discontinuing Treatment with Venlafaxine Hydrochloride Extended Release Capsules
A gradual reduction in the dose, rather than abrupt cessation, is recommended when discontinuing therapy with venlafaxine hydrochloride extended release capsules. 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. In some patients, discontinuation may need to occur over a period of several months [see Warnings and Precautions (5.7)] .
2.11 Switching Patients to or from a Monoamine Oxidase Inhibitor (MAOI) Antidepressant
At least 14 days must elapse between discontinuation of an MAOI antidepressant and initiation of venlafaxine hydrochloride extended-release capsules. In addition, at least 7 days must elapse after stopping venlafaxine hydrochloride extended-release capsules before starting an MAOI antidepressant [see Contraindications (4), Warnings and Precautions (5.2), and Drug Interactions (7.1)] .
