Mycophenolate: Indications, How to Use, Side Effects, Precautions and Interactions

It is an immunosuppressive medicine derived from Penicillium stolonifera.

Mycophenolate mofetil is a prodrug of mycophenolate (MPA). After oral administration, mycophenolate mofetil is rapidly absorbed and hydrolyzed (converted) to MPA.

MPA is the active metabolite that has pharmacological activity.


Mycophenolate is used with other medications to prevent your body from attacking and rejecting your transplanted organ (kidney, liver, or heart).

It belongs to a class of medications called immunosuppressants. It works by weakening your body’s defense system (immune system) to help your body accept the new organ as if it were yours.
