Warfarin is in a class of medications called anticoagulants (blood thinners) that works by decreasing the clotting ability of the blood. It is prescribed for people with certain types of irregular heartbeat, prosthetic heart valves, and for those who have had a heart attack. Warfarin is also used to treat or prevent venous thrombosis ( blood clot in a vein) and pulmonary embolism (a blood clot in the lung).
