Due to blood in my urine and extreme stomach cramps, I was taken off my Plavix which I had been on for 3 years following a heart attack. I am hoping someone can tell me how long it stays in your system after stopping it. Been off it now for 8 days and still having some cramps though not as severe and so far no more bloody urine. My Dr. did tell me he wanted me to stay on my asprin however along with the protonix. The protonix doesn't seem to help much any more--any suggestions?
