Sounds like you may have to go to something stronger. When my bleeding wouldn't stop they tried me on 6mp, but I was allergic. Finally I had to do remicade. And that is the only thing that stopped the bleeding. Be careful of losing too much blood. I had to do several transfusions. And that is no fun. As long as your dr. is aware, you should be okay. I would stay on him though, I had stay on my dr. for over a year before he finally got serious with my UC. Good luck.
