Azacitidine is used to treat myelodysplastic syndromes (a group of disorders in which blood-forming cells in the bone marrow do not become healthy blood cells).
It is also used to treat chronic myelomonocytic leukaemia (a type of chronic cancer of the blood in which a person's bone marrow does not make blood effectively) and acute myeloid leukaemia (a type of blood cancer where the bone marrow produces too many white blood cells).
This medicine may be used to treat other conditions as decided by your doctor.

Your doctor or nurse will administer the injection for you.
The dose of this medicine will be decided by your doctor. Your doctor will advise you on the course of your treatment depending on the severity of your condition and your response to the medication.

This medicine will cause the level of your red blood cells, white blood cells and platelets to drop.
Red blood cells carry oxygen around your body. A fall in the level of red blood cells may make you feel tired and worn out.
White blood cells help your body to fight infections. A fall in the level of your white blood cells may put you at higher risk for infections, such as coughs, colds and flu, which may lead to more serious infections. Avoid crowded places and people who are sick. Alert your doctor if you have a fever, or a cough or flu that does not go away.
Platelets help your blood to clot when there is a cut in the skin. A fall in the level of your platelets may put you at risk of bleeding more than usual. Do not take part in activities where you may fall or get injured, such as contact sports. Alert your doctor if you get any unusual bruising (large bruises or several bruises, especially if the bruises appeared on their own) or bleeding that takes a long time to stop (for example, too much bleeding when you floss or brush your teeth).
Inform your doctor if any of these side effects do not go away or are severe, or if you experience other side effects.
Always notify your doctor and pharmacist if you are taking or using any other medicines, including herbal tonics such as traditional Chinese medicines, supplements, and medicines that you buy without a prescription.
Avoid alcohol.
Store in a cool, dry place away from the reach of children.
Medicines must not be used past the expiry date.
As Azacitidine is a cancer medicine, always return any unused or expired vial to the clinic, hospital, or pharmacy for disposal. Do not throw it away in the household waste.
