I was on Plavix and baby aspirin following diagnosis of hear problems. A few years later, I fell and skinned my knee. The knee wouldn't stop bleeding. Had to go to the Emergency Room.
Some advice to anyone taking this driug long-term: Periodically ask your doctor if you should continue to take it. Eight years after I first started taking Plavix, someone told me I probably should be off the drug. Apparently, after 5 years, unless there is still a serious problem where a patient has to keep taking Plavix, the drug should be discontinued. So I asked the cardiologist and he said, yes, I was right. I don't need Plavix anymore.
In fact, it's probably a good idea once in a while to review all your meds with your doctor to see if any are still necessary or if maybe there is something that works better.
