@maize Welcome to Mayo Clinic Connect! I’m currently on mycophenolic acid for about 2 years but haven’t noticed and hair loss. I was on mychophenelate mofitil before that and I had serious diarrhea for about 4 months before the doctor could change drugs. I have Clippers, a rather new AD that just showed up long enough for me to catch it. It causes lesions on the brain. What AD do you have?
