Overview

Venlafaxine is a prescription medication used to treat major depressive disorder, generalized anxiety disorder, social anxiety disorder, and panic disorder in adults. It belongs to a class of antidepressants called serotonin-norepinephrine reuptake inhibitors (SNRIs), which work by increasing the levels of serotonin and norepinephrine in the brain.

Patients should not stop taking venlafaxine suddenly without consulting their healthcare provider, as this can cause withdrawal symptoms.
