Mofecon 250 Mofecon 250 is an immunosuppressive tablet containing mycophenolate mofetil 250 mg. It is used to reduce excessive immune-system activity, particularly in patients who have received an organ transplant. By limiting the activity and multiplication of certain immune cells, it helps reduce the possibility of the body rejecting the transplanted organ. It is generally used together with other prescribed immunosuppressive medicines under specialist supervision.
