What is Mycophenolate Mofetil used for?
Mycophenolate is used in combination with other medications to keep your body from attacking and rejecting your transplanted organ (such as kidney, liver, 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 your own.
