Warfarin? Warafin is a common misspelling of warfarin.
Warfarin sodium (Coumadin®, Jantoven®) is a medication commonly prescribed for the prevention and treatment of blood clots due to various causes. It is a type of anticoagulant that works by inhibiting the recycling of vitamin K in the body, which decreases the formation of active clotting factors. Once a blood clot forms, warfarin keeps the clot formation in check, allowing the body's natural processes to break it down. This drug comes in tablet form and is available in nine different strengths.
