Your doctor will tell you how long you need to take warfarin for, and when you can stop. Make sure you know who is going to tell you when to stop and when you need to see them. This may be your specialist or your GP. After stopping warfarin your blood will return to normal in a few days.

Don't stop taking warfarin unless told by your doctor. Stopping warfarin before it is safe means blood clots might form.

If you can't take your warfarin for any reason (such as illness) tell your healthcare professional. Extra blood tests may be needed.
