Coumadin is used for treating and preventing harmful clots that may occur in the veins (venous thrombosis), in the lungs (pulmonary embolism), with a type of abnormal heartbeat (atrial fibrillation), or following a heart valve replacement. Coumadin is also used to reduce the risk of stroke and other problems in patients who have had a heart attack. Coumadin is an anticoagulant. It works by blocking the synthesis of certain clotting factors. Without these clotting factors, blood clots are unable to form.
