@Erinmfs, @becsbuddy, I am taking cellcept (mycophenolate mofetil) to prevent rejection of my liver and kidney transplant. I have not had any bothersome side effects, although my transplant team keeps a close watch on my labs, and have advised about sun protection and about staying up-to-date with my routine health screenings. I take mine at 8 AM and at 8 PM. I don't know whether taking it got autoimmune conditions has a different effect that taking it for transplant, but I have taken it for 12 years. If you have any questions, I'll try to help.
