To treat Autoimmune Hepatitis. Anyone out there with AIH had good luck with this drug? Tried Imuran in April but after 3 wks it made me very sick vomiting/diarrhea. Any info would be appreciated... thx so much! Also down to 5mgs of prednisone and finally starting to feel better. Now I have to be on this 6mp and am very scared about more bad side effects! HELP!!
