Overview
Effexor (venlafaxine) is a serotonin-norepinephrine reuptake inhibitor (SNRI) approved for major depression, generalized anxiety disorder, social anxiety disorder, and panic disorder. It's often effective when SSRIs haven't provided adequate relief. At Next Step Psychiatry, we prescribe Effexor XR (extended-release) for its once-daily convenience and reduced side effects compared to immediate-release formulations.
How Effexor Works
Venlafaxine inhibits the reuptake of both serotonin and norepinephrine. At lower doses, it primarily affects serotonin (similar to SSRIs). At higher doses (typically above 150 mg), norepinephrine effects become more prominent, which may provide additional benefit for some patients.

Frequently Asked Questions
Is Effexor hard to stop taking?
Yes, Effexor is known for potentially severe discontinuation symptoms. It has a short half-life, meaning levels drop quickly between doses. Tapering must be done very slowly, sometimes over months, under medical supervision.
Does Effexor raise blood pressure?
Effexor can cause sustained increases in blood pressure, particularly at higher doses. Blood pressure should be monitored regularly, especially during dose increases.
Why would someone try Effexor after SSRIs?
Effexor affects both serotonin and norepinephrine (SNRIs), while SSRIs only affect serotonin. The additional norepinephrine effect may help patients who haven't responded fully to SSRIs, particularly for severe depression or pain symptoms.
