Taking plavix and having bad side effects?

Your nose is full of tiny blood vessels called capillaries. In the general sense Plavix is a blood-thinner, making these capillaries more prone to leakage of small amounts of blood. Damage to the carotid has the potential for accumulating an unstable clot which could choke off carotid blood supply to the head or dislodge and travel to the brain or eye, potentially resulting in permanent damage (like blindness or stroke) or even death. Plavix keeps these clots from occuring. So while your nose congestion may be irritating and uncomfortable, the consequences of discontinuing the Plavix could be life-threatening, and I would advise you to take it until your physician contacts you.
