Are there any risks in taking Plavix?

In addition to increased risk of internal bleeding, Plavix can also cause thrombotic thrombocytopenic purpura. This is a condition in which blood clots form from burst red blood cells, depriving organs of blood supply. Because blood does not clot normally, you should try to avoid cuts and bruises as much as possible when taking Plavix, as it may be difficult to stop the bleeding; do not participate in high contact sports, for example.
