Mycophenolate mofetil tablets (brand name options include Cell Cept and various generics) are a powerful prescription immunosuppressant medication used primarily to prevent the body from rejecting a transplanted organ. 

Key Information

• Primary Use: Used in combination with other medications (like cyclosporine and corticosteroids) to prevent the immune system from attacking a transplanted kidney, heart, or liver.

• Mechanism: It works by suppressing the body's natural immune response, specifically by inhibiting the growth and function of the white blood cells (T and B lymphocytes) responsible for organ rejection.
