If you have had only one atrial fibrilation episode and are on coumadin, (warfarin) when can you stop this medication?
Depends. That is a tough question and a matter of opinion. Whether you need Coumadin (warfarin) in the first place depends on the chad score (how many risk factors you have). If the afib was related to a temporary situation, such as surgery, it is more likely that the Coumadin (warfarin) can be stopped. Exactly when, is partly a matter of opinion. The longer you go without recurrence, the more likely it is safe to stop.
