Pristiq is the brand name for desvenlafaxine, a prescription drug used to treat depression. It is an antidepressant in a group of drugs called selective serotonin and norepinephrine reuptake inhibitors (SNRIs). Pristiq affects chemicals in the brain that may become unbalanced and cause depression.
Pristiq is used off label for generalized anxiety disorder to some success, although a few studies have shown mixed results. Even though Pristiq is off label, two other SNRIs (Cymbalta and Effexor XR) have been approved for anxiety use, so there is reason to believe that Pristiq may be approved for the same purpose.
