Warfarin – Oral

Why do I need this medicine?

Warfarin is a blood-thinning medicine. It prevents special cells in the blood from sticking to each other. This reduces the risk of harmful blood clots forming in the body. Blood clots that form in a blood vessel inside the heart or brain can cause a heart attack or a stroke.

This medicine is used to reduce the risk of stroke and heart attack in people who have a high risk of getting them. This includes people who have had a stroke or heart attack before and are at risk of getting another stroke or heart attack; and people with medical conditions that may increase their chances of getting them.

This medicine is also used to prevent blood clots in people with artificial heart valves or those with faulty heart valves.

Warfarin is also used to prevent blood clots from forming in the leg veins (deep vein thrombosis or DVT) and the vessels of the lungs (pulmonary embolism or PE).
