What is Vidaza?

Vidaza (azacitidine) is a cancer medicine that interferes with the growth and spread of cancer cells in the body.

Vidaza is used to treat certain types of bone marrow cancers and blood cell disorders.

Vidaza may also be used for purposes not listed in this medication guide.

Important information

You should not receive Vidaza if you have advanced liver cancer.

Vidaza can lower blood cells that help your body fight infections and help your blood to clot. You may get an infection or bleed more easily. Call your doctor if you have unusual bruising or bleeding, or signs of infection (fever, chills, body aches).

Before taking this medicine

You should not receive Vidaza if you are allergic to azacitidine or mannitol, or if you have:

  • advanced liver cancer.

To make sure Vidaza is safe for you, tell your doctor if you ever have:

  • kidney disease; or

  • liver disease.

Both men and women using Vidaza should use effective birth control to prevent pregnancy. Azacitidine can harm an unborn baby or cause birth defects if the mother or father is using this medicine.

You should not breast-feed while using azacitidine.

How is Vidaza given?

Vidaza is injected under the skin, or into a vein through an IV infusion. A healthcare provider will give you this injection.

This medicine is usually given for 7 days in a row every 4 weeks for at least 4 treatment cycles. Your treatment schedule may be different. Follow your doctor's instructions.

You may also be given medications to reduce nausea and vomiting while you are receiving Vidaza.

If Vidaza accidentally gets on your skin, wash the area thoroughly with soap and warm water.

Azacitidine can lower blood cells that help your body fight infections and help your blood to clot. Your blood will need to be tested often. Your kidney function may also need to be tested. Your cancer treatments may be delayed based on the results.
