Warfarin

Common brand names:

Coumadin, Jantoven

Warfarin is an anticoagulant (slows blood clotting) used to prevent and treat people with venous thrombosis (blood clots in the veins) and pulmonary embolism (blood clots in the lungs). Warfarin is also used to treat or prevent dangerous blood clotting in people with atrial fibrillation (an irregularity in heartbeat) and, in some cases, to prevent stroke.
