How does warfarin (Coumadin) treat deep vein thrombosis (DVT)?

ANSWER

You may take warfarin (Coumadin) by pill once a day, starting while you're still on heparin, and then usually for 3 to 6 months or more. While you take it, you'll need regular blood tests to make sure you've got the right amount in your system -- too little won't prevent clots, and too much makes dangerous bleeding more likely. It can also interact with other medicines, vitamins, and foods with a lot of vitamin K, which is another good reason to get your blood checked often.

Let your doctor know if you're pregnant, because warfarin can cause birth defects. You'll have to take something else.
