Your doctor will tell you how long you need to take warfarin for, and when you should stop taking it. Some people will take warfarin long term, for as long as their blood-clotting risk continues. Other uses (such as after surgery) are usually short term.
While using warfarin, you will need to have your blood levels of the drug checked frequently at the medical clinic or hospital. Your doctor will want you to stay within an established range to help keep your blood thin enough to prevent clots, but not so thin as to cause bleeding.
