@altabiznet. People seem to ask this question frequently. The only real difference is in the GI tract. I took cellcept for about 2 years and i suddenly developed diarrhea. My doctor instantly changed me to Myfortic. Neither of us knew that I had developed EPI (exocrine pancreatic insufficiency) which caused an almost 2 years adventure with diarrhea and weight loss (due to malnutrition). We finally got things under control. In the process, I fired my GI doctor and got a new one!
I have tolerated the Myfortic with no problem. In fact, I’m off of it now and just take Rituxan twice a year!
