• Immunosuppressant
• monoclonal antibody

Daclizumab (da-KLIZ-yoo-mab) belongs to a group of medicines known as immunosuppressive agents. It is used to lower the body's natural immunity in patients who receive kidney transplants.

When a patient receives a kidney transplant, the body's white blood cells will try to get rid of (reject) the transplanted kidney. Daclizumab works by preventing the white blood cells from getting rid of the transplanted kidney. The effect of daclizumab on the white blood cells may also reduce the body's ability to fight infections.

Daclizumab is to be administered only by or under the immediate supervision of your doctor. It is available in the following dosage form:

Parenteral
• Injection (U.S.)

In deciding to use a medicine, the risks of receiving the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For daclizumab, the following should be considered:

Allergies—Tell your doctor if you have ever had any unusual or allergic reaction to daclizumab. Also tell your health care professional if you are allergic to any other substances.

Pregnancy—Daclizumab crosses the placenta. However, daclizumab has not been studied in pregnant women.

Breast-feeding—It is not known if daclizumab passes into breast milk. Breast-feeding is not recommended for patients receiving daclizumab.

Children—Studies on the use of daclizumab in children have not been completed. However, daclizumab may cause high blood pressure and dehydration more often in children than it does in adults.

Older adults—Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of daclizumab in the elderly with use in other age groups.

• Cancer—Daclizumab may make this condition worse

• Diabetes mellitus (sugar diabetes)—Daclizumab can increase the amount of sugar in the blood

• Infection—Daclizumab may decrease the body's ability to fight infection

Dosing—

The dose of daclizumab will be different for different patients. Your doctor will decide what dose should be used for you based on your body weight. The following information includes only the average doses of daclizumab.

    • Adults or children—1 milligram (mg) per kilogram (kg) (0.45 mg per pound) of body weight.

If you are continuing your course of therapy with daclizumab after you are discharged from the hospital, it is very important that your doctor check your progress at regular visits. Your doctor will want to do laboratory tests to make sure daclizumab is working properly.
