Mycophenolate decreases the body's ability to protect against illness and infection, and may also increase your risk of developing lymph node tumors (lymphoma) and other types of cancer (especially skin cancer). Therefore, this medication must only be given under close medical supervision. Discuss the risks of taking mycophenolate with your doctor.
Notify your doctor immediately if you develop signs of infection (such as persistent sore throat or fever) or other symptoms such as weight loss, night sweats, enlarged lymph nodes, or skin changes/growths.
Women of childbearing age must use reliable forms of birth control when using mycophenolate, since it may harm an unborn baby. (See also Precautions).Who should not take mycophenolate mofetil?
Mycophenolate is used in combination with other medications to keep your body from attacking and rejecting your transplanted organ (e.g., kidney, liver, heart). It belongs to a class of medications called immunosuppressants. This medication works by lowering your body's immune system activity.

Take this medication as directed, usually twice daily on an empty stomach, one hour before or two hours after meals.
Swallow this medication whole. Do not crush or chew. If you are taking the capsules, do not open them before swallowing.
Certain drugs may decrease the amount of mycophenolate that your body absorbs if taken at the same time. Do not take this medication at the same time as antacids containing aluminum and/or magnesium, cholestyramine, colestipol, or calcium-free phosphate binders (e.g., aluminum products, lanthanum, sevelamer). For more details, ask your pharmacist.
Use this medication regularly in order to get the most benefit from it. Remember to use it at the same times each day. Dosage is based on your medical condition and response to therapy.
