High Blood Pressure (Hypertension)

Severe Potential Hazard, High plausibility

venlafaxine - hypertension

The use of venlafaxine is associated with dose-dependent, sustained increases in blood pressure, mostly in the range of 10 to 15 mm Hg for supine diastolic blood pressure. The incidence reported for immediate-release venlafaxine in a premarketing study ranged from 3% for dosages < 100 mg/day to 13% for dosages > 300 mg/day. Therapy with venlafaxine should be administered cautiously in patients with preexisting hypertension. Blood pressure should be monitored regularly, and the dosing reduced or discontinued if necessary.
