@kidney091967, I'm not very sensitive to most medications, but a lot of people here on Mayo Connect are. So, you are not alone. I'm a firm believer that we can learn and get so much from others who have similar experiences to what we experience. If you end up going on Cellcept, let us know how you do with it. I've been on it since my transplant (16 months ago), with no major side effects so far, but that might not be your experience. All the best to you as you and your docs try to figure this out and get you some relief.
