Diagnosed Feb2012. Currently doing a prednisone tapering at 12.5mgs daily soon to go down to 10mgs daily pending blood work results from 30June. Tried Imuran in Apr2012. Could only tolerate 30days. Severe vomiting/diarrhea stomach problems. Dr wants to start Cellcept when I get down to 7.5mgs of prednisone. I need any info about this disease, medicines, side effects, etc that anyone can give me. Please help me!!! I am very scared. 57yr old female. Thanks so much!!!
