What is Warfarin?

Warfarin (Coumadin) is an anticoagulant or "blood thinner." Anti means against, and coagulant refers to blood clotting. An anticoagulant helps reduce the risk of clots forming in the blood. Your physician will give you warfarin if he/she has determined that you have a medical condition that requires treatment with a medication to prevent your blood from forming blood clots when it shouldn't. This treatment is called anticoagulation.
Warfarin is a prescription medicine used to prevent blood clots from forming in your blood. It is sometimes called a "blood thinner." It is prescribed for the following people:
  • those with certain types of irregular heartbeat
  • those with artificial replacement heart valves
  • those who have suffered a heart attack
  • those with swelling and blood clot in a vein (known as venous thrombosis)
  • those with a blood clot in the lung (known as pulmonary embolism)
