Mycophenolate mofetil (MMF) is an immunosuppressive agent that inhibits both T- and B-cells. There is limited information in veterinary medicine. Mycophenolate is most commonly used as part of multi-modal therapy for a variety of immune-mediated diseases. The addition of MMF can sometimes reduce and eliminate the need for high-dose corticosteroids.

Injectable mycophenolate is a good option for conditions where oral administration of secondary immunosuppressive agents is not possible or not desired, for example due to vomiting/regurgitation or impaired mentation. Depending on response to treatment, patients may be switched to oral forms of the medication for longer-term management.
