Mofecon 750 Mofecon 750 is an oral immunosuppressant containing mycophenolate mofetil 750 mg. It works by reducing the activity of specific immune cells that can recognize a transplanted organ as foreign and attack it. This helps lower the risk of organ rejection and is commonly used as part of a combination of anti-rejection medicines following organ transplantation. Treatment should be taken only under the supervision of a qualified healthcare professional.
