Understanding Venlafaxine: Benefits and Risks for Anxiety and Depression

Venlafaxine, a selective serotonin-norepinephrine reuptake inhibitor (SSNRI), is a widely prescribed medication for treating anxiety and depression. As with any medication, it's essential to weigh the benefits against the risks to make an informed decision.

Benefits of Venlafaxine

*

“significantly reduce symptoms of depression and anxiety in patients with major depressive disorder and generalized anxiety disorder.”

(1)
* Improve sleep quality and reduce insomnia (2)
* Enhance cognitive function and memory (3)
* Have a rapid onset of action, with effects typically seen within the first week of treatment (4)
