How an SNRI Is Thought to Work

Effexor XR (venlafaxine HCl) is a prescription medication used to treat depression, generalized anxiety disorder, and social anxiety disorder, allowing you to get back to your life again.

Effexor XR is known as an SNRI (serotonin and norepinephrine reuptake inhibitor) and is believed to help treat depression and the associated symptoms of anxiety by affecting the levels of two chemicals in the brain - serotonin and norepinephrine.

These two chemicals are thought to play a key role in depression and the associated symptoms of anxiety. Correcting the imbalance of these two chemicals may help relieve depression symptoms and the associated symptoms of anxiety - which can be a positive step toward getting your life back.
