NO!Excedrin contains aspirin, and even the amount of a baby aspirin can cause bleeding if taken within 2 weeks before surgery.Some surgeons may say 1 week is OK, and some surgeons say ibuprofen (Advil, Motrin, Nuprin) or Aleve or OK. But most of us will ask you to avoid all of those for 2 weeks before elective surgery.If they really believe it's OK, I think it's sort of like saying, "Well, a little bleeding might be OK and might not lead to a re-operation!"Why chance it? Tylenol will not cause bleeding, though it may not work as well as these other medications for a headache. But acetaminophen (Tylenol) doesn't cause bleeding. Best wishes! Dr. Tholen
