What is mycophenolic acid (Myfortic)?
Mycophenolic acid weakens your body's immune system, to help keep it from "rejecting" a transplanted organ such as a kidney. Organ rejection happens when the immune system treats the new organ as an invader and attacks it.
Mycophenolic acid is used with other medicines to prevent organ rejection after a kidney transplant.
Mycophenolic acid may also be used for purposes not listed in this medication guide.
