Warfarin
Anticoagulant (vitamin K antagonist)
Warfarin is a prescription anticoagulant (blood thinner) used to prevent and treat blood clots in conditions such as deep vein thrombosis, pulmonary embolism, atrial fibrillation, and to reduce the risk of stroke and heart attack. It works by blocking the action of vitamin K, which the body uses to make clotting factors that cause blood to coagulate. By slowing clot formation, Coumadin helps maintain smooth blood flow through the vessels.
