Venlafaxine is a serotonin-norepinephrine reuptake inhibitor (SNRI) antidepressant used to treat major depressive disorder (MDD), generalized anxiety disorder (GAD), and other mood disorders. By blocking the reuptake of serotonin and norepinephrine neurotransmitters in the brain, Venlafaxine increases their levels in the synaptic space, which helps to alleviate symptoms of depression and anxiety. Unlike some other antidepressants, Venlafaxine also exerts a dose-dependent effect on the reuptake of dopamine, further contributing to its antidepressant properties.

One of the key features of Venlafaxine is its efficacy in treating both depressive and anxiety symptoms, offering comprehensive relief for individuals with comorbid mood and anxiety disorders. Venlafaxine is available in various extended-release formulations, allowing for once-daily dosing and providing sustained symptom relief throughout the day. Additionally, Venlafaxine has been studied for its potential benefits in managing neuropathic pain conditions, such as diabetic neuropathy and fibromyalgia, further expanding its therapeutic utility beyond mood disorders.
