Pristiq XR (Desvenlafaxine) is an extended-release antidepressant manufactured by Pfizer. It belongs to the serotonin-norepinephrine reuptake inhibitor (SNRI) class of medications and is FDA-approved for the treatment of major depressive disorder (MDD) in adults. Desvenlafaxine is the active metabolite of Venlafaxine (Effexor XR). It is also used off-label for generalized anxiety disorder, hot flashes associated with menopause, panic disorder, neuropathic pain, and fibromyalgia.
Pristiq XR works by inhibiting the reuptake of serotonin and norepinephrine in the brain. By blocking the reabsorption of these two key neurotransmitters, Desvenlafaxine increases their levels in the synaptic cleft, which helps improve mood and relieve symptoms of depression. The extended-release formulation allows for once-daily dosing. Tablets should be swallowed whole and not crushed, chewed, or dissolved. It can be taken with or without food.
