CellCept (mycophenolate mofetil) is an immunosuppressant, a medicine that lowers your body's immune system. The immune system helps your body fight infections. Your body may "reject" an organ transplant when the immune system treats the new organ as an invader. An immunosuppressant helps to prevent this rejection. CellCept is used to prevent your body from rejecting a kidney, liver, or heart transplant. CellCept is usually given with cyclosporine (Sandimmune, Neoral) and a steroid medication.
