How to use Azacitidine

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Azacitidine oral (Onureg) is taken by mouth in a 28-day treatment cycle. You may need to take the medicine only during the first 2 weeks of each cycle.

Take Onureg at the same time each day, with or without food. Swallow the tablet whole and do not crush, chew, or break it.

Do not use a broken tablet. The medicine from a broken pill can be dangerous if it gets in your mouth, eyes, or nose, or on your skin. If this happens, wash your skin with soap and water or rinse your eyes with water.

If you vomit shortly after taking Onureg, do not take another dose. Wait until your next scheduled dose time to take the medicine again.

Azacitidine injection (Vidaza) is injected under the skin, or given as an infusion into a vein. A healthcare provider will give you this injection, usually for 7 days in a row every 4 weeks for at least 4 treatment cycles.

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

Your treatment schedule may be different. Your doctor will determine how long to treat you with azacitidine. Onureg should not be used in place of Vidaza. The oral and injection forms of this medicine have different uses and dosages.

You may also be given medicine to reduce nausea and vomiting. Use this medicine only as prescribed.

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.

Store Onureg at room temperature away from moisture and heat. Keep the tablets in their original container, along with the packet or canister of moisture-absorbing preservative. Keep the container tightly closed when not in use.

Warnings

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

You should not be treated with azacitidine injection if you are allergic to mannitol, or if you have advanced liver cancer.
