Hi, my son has Mpa from March 2017 and he takes prednisone, mycophenolate (myfortic) and ramipril. He's doing well apart from diarrhea caused by mycophenolate. He had to stop mmf for a week and he became almost costipated. The doctor say not to worry because mmf is to important for him but I would like to know if someone has a similar experience and how i can help him. I've tried with diet and probios without success. Thank you in advance for your advices.
