What is Warfarin, and what does it do?
Harmful blood clots can result in a stroke, heart attack, Deep Vein Thrombosis, or Pulmonary Embolism. Warfarin is a prescription drug and anticoagulant used to prevent the formation or growth of dangerous blood clots.
Many people refer to anticoagulants as “blood thinners,” but Warfarin does not thin the blood; instead, it causes the blood to take longer to clot.
The formation of a clot in the body is a complicated process involving a number of substances known as clotting factors. Warfarin inhibits the formation of vitamin K–dependent clotting factors, reducing the body’s ability to form blood clots. Vitamin K is required for the production of clotting factors and the prevention of bleeding. As a result, by administering a medication that inhibits clotting factors, your body can prevent harmful clots from forming and clots from growing in size.
