Hi Sariah,
Like Suzanne, I had a kidney transplant in March of 06. I had been on cellcept prior to the transplant for the auto immune disease, and had the bad diarrhea. It also took a little bit for it to kick in. I ended up having to go off of it. After my transplant, they put me on Myfortic for anti-rejection, which they describe as another form of cellcept, again, just like Suzanne said, it's absorbed differently, and I've been able to tolerate that just fine. Cellcept is a great drug if you can tolerate it, hope it works for you! I'm fortunate enough that I haven't had to go back on the prednisone. Keeping my fingers crossed.
