I was diagnosed with MG in 2002. I have been on several different treatments. I used Immuran for a few years, I had alot of side effects with Immuran. I have been on Cellcept for a few years now and its been the best meds yet for me. I have seen any side effects. I would say my life is back to normal. Its been alot more expensive but worth every dime.I highly recommend Cellcept. I have had no memory loss from its use, but I have had memory problems from the MG.
