    What is Coumadin (Warfarin) used for?

    Warfarin is used in the treatment of blood clots as well as to prevent new clots from forming in your body. Preventing blood clots can help reduce your risk of a pulmonary embolism, heart attack or stroke. There are some conditions that can increase your risk of developing clots. These include atrial fibrillation, recent heart attack, some surgeries, and heart valve replacement. Coumadin is generally called a “blood thinner” but the more accurate term is anticoagulant. It helps keep blood smoothly flowing in your body by decreasing the amount of clotting proteins in your blood.
