I have atrial fibrillation. Why do I have to be on Coumadin?
To reduce bleeding from various places such as the stomach, intestines, nose, bladder, and even what might be thought to be minor cuts on the skin. The Coumadin must be held for a period of time and the dose reduced. If the blood is extremely thin, a shot of vitamin K, the antidote, must be given to reverse the effects of this blood thinner. There have been a number of studies which have shown that Coumadin is beneficial in reducing the number of strokes in those who have chronic or intermittent atrial fibrillation. This is especially true in those who are in their sixties or older. In younger patients with intermittent atrial fibrillation, there is currently a tendency to treat it with only aspirin. However, if you have atrial fibrillation that is established or is chronic, no matter your age, most physicians would recommend Coumadin. Some medications such as sulfa make the Coumadin work better and make the blood too thin. At the other end of the spectrum are foods rich in vitamin K.
