What is warfarin? Warfarin is an anticoagulant (blood thinner). Warfarin reduces the formation of blood clots. Warfarin is used to treat or prevent blood clots in veins or arteries, which can reduce the risk of stroke, heart attack, or other serious conditions. Warfarin may also be used for purposes not listed in this medication guide.
Answers. Best Answer: Warfarin is a type of drug that acts on your intrinsic coagulation pathway (in your liver). Besides cleaning out your blood, the liver also creates several clotting factors that help your platelets stick together to form clots. One of these factors is Vitamin K. It itself does not stick to platelets. Rather, it helps the other factors transform and bind together. Long story short, warfarin keeps your liver from making vitamin K and your gut from absorbing it. How long it stays depends on your liver's ability to make vitamin K to use up the remaining warfarin.
