What is warfarin-induced skin necrosis?
Warfarin is an anticoagulant medicine (blood thinner). Warfarin-induced skin necrosis refers to a rare condition in which there is paradoxical blood clotting. Blood clots block the blood vessels and cause necrosis, where an area of skin is destroyed. Warfarin-induced skin necrosis affects one in every 10,000 patients prescribed warfarin.
