This medication is used to prevent and treat rejection of a kidney transplant. This medication belongs to a class of drugs known as immunosuppressants. It works by decreasing your body's natural defense (immune system). This helps prevent your body from rejecting the kidney transplant so it can work normally.

This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This drug may also be used for certain blood disorders (aplastic anemia, myelodysplastic syndrome).

Before receiving this medication, you may be directed to take other medicines (such as acetaminophen, antibiotic, antihistamine, corticosteroid) to decrease side effects during your treatment.

This medication is given by a health care professional as directed by your doctor. The dosage is based on your weight, medical condition, lab tests, and response to treatment. It is slowly injected into a vein, usually over at least 4 to 6 hours. Tell your doctor or nurse right away if you notice redness, pain, or swelling during your injection.

Follow your doctor's directions for taking your other medications to help prevent your body from rejecting the kidney transplant or to prevent infection. Ask your doctor or pharmacist if you are not sure how to take any of your medicines.

Nausea, fever, chills, diarrhea, dizziness, headache, or tiredness may occur. Redness, pain, or swelling at the injection site may also occur. If any of these effects last or get worse, tell your doctor promptly.

People using this medication may have serious side effects. However, you have been prescribed this drug because your doctor has judged that the benefit to you is greater than the risk of side effects. Careful monitoring by your doctor may decrease your risk.

Tell your doctor right away if you have any serious side effects, including:

• easy bruising/bleeding
• fast/irregular heartbeat
• joint/muscle pain
• severe stomach/abdominal pain
• weakness

Because this drug works by weakening the immune system, it may lower your ability to fight infections. This may make you more likely to get a serious (rarely fatal) infection or make any infection you have worse. Tell your doctor right away if you have any signs of infection (such as cough, sore throat, fever, chills, pain when urinating).

This medication may increase the risk of developing certain types of cancer. Consult your doctor for details.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including:
