Azacitidine is used to treat myelodysplastic syndrome (a group of conditions in which the bone marrow produces blood cells that are misshapen and does not produce enough healthy blood cells). Azacitidine is in a class of medications called demethylation agents. It works by helping the bone marrow to produce normal blood cells and by killing abnormal cells in the bone marrow.
Azacitidine comes as a powder to be mixed with water and injected subcutaneously (under the skin) or intravenously (into a vein) by a doctor or nurse in a medical office or hospital outpatient department. It is usually injected once a day for 7 days. This treatment may be repeated every 4 weeks for as long as your doctor recommends. Treatment should usually be given for at least four cycles.
Your doctor may increase your dose of azacitidine after two cycles if your condition has not improved and if you have not experienced serious side effects of the medication. Your doctor may also need to delay your treatment or reduce your dose if you experience certain side effects. Be sure to tell your doctor how you are feeling during your treatment with azacitadine.
Your doctor will give you medication to prevent nausea and vomiting before you receive each dose of azacitadine.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
Unless your doctor tells you otherwise, continue your normal diet.
Call your doctor right away if you are unable to keep an appointment to receive a dose of azacitidine.
