Vidaza is an anti-cancer agent. Vidaza contains a medicine called azacitidine which prevents the growth of cancer cells. Vidaza has been prescribed by your doctor for the treatment of myelodysplastic syndrome (MDS). Myelodysplastic syndrome is a blood disorder in which the bone marrow is not working normally and does not produce enough mature blood cells. This causes a lack of healthy blood cells that can function properly in the body.
Ask your doctor if you have any questions about how Vidaza works, or why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
Vidaza will only be prescribed to you by a doctor who has experience in medicines to treat cancers of the blood.


When you must not be given Vidaza

Tell your doctor:
If you are allergic to azacitidine or any of the other ingredients of Vidaza listed at the end of this leaflet.
Some of the symptoms of an allergic reaction may include:
shortness of breath
wheezing or difficulty breathing
swelling of the face, lips, tongue or other parts of the body
rash, itching or hives on the skin.
If you have advanced liver cancer.
If you are pregnant.
If you have severe problems with your kidney function.

Before you are given Vidaza

1.Use by women

Avoid becoming pregnant while receiving Vidaza but if you do, tell your doctor immediately.
Use an effective method of contraception during treatment with Vidaza and for up to three (3) months after discontinuation of Vidaza.
Do not breast-feed while you are receiving Vidaza but if you do, tell your doctor immediately.
It is not known if Vidaza is excreted in human milk.

2.Use by men

Do not father a child while receiving treatment with Vidaza.
Use barrier methods of contraception (e.g. condoms) during treatment and for up to three (3) months after discontinuation of Vidaza, if your partner is of childbearing potential.
Talk to your doctor if you wish to conserve your sperm before having this treatment.

3.Use by all patients

Tell your doctor if you have any allergies to any other medicines, foods, preservatives or dyes.
Do not give Vidaza to children (under 18 years).
Before receiving Vidaza, tell your doctor if you have had any heart problems or lung disease.
You will have blood tests before you begin treatment with Vidaza and at the start of each period of treatment (called a ‘cycle’). This is to check that you have enough blood cells and that your liver and kidneys are working properly.
If you are older than 65 years, your doctor will give you the regular blood tests described above but may also check your kidney function during your treatment with other tests.

Taking other medicines

Tell your doctor if you are taking any other medicines or have recently taken any other medicines, including any medicines that you buy without a prescription from a pharmacy, supermarket or health food shop.


Vidaza will be given to you as an injection under the skin (subcutaneously i.e. under the skin on your thigh, abdomen or upper arm) or as an intravenous infusion by a doctor or a nurse.
Your doctor will choose the correct dose of Vidaza for you.
Your dose will depend on your general condition and your height and weight.
Your dose will be calculated based on your body surface area, with the usual dose of 75 mg Vidaza per metre squared of body surface area.
Initially, Vidaza will be given daily for 7 days. 21 days later, you will have Vidaza for another 7 days. This is called a ‘cycle’. The cycle is repeated every 28 days for a minimum of 6 cycles.
Your doctor will check your progress and may change your dose if necessary.
Vidaza can cause nausea and vomiting. To stop you from getting sick (nausea and vomiting), your doctor may give you another medicine at the start of each treatment cycle with Vidaza.
If you have any further questions on the use of Vidaza, ask your doctor or pharmacist.

If you are about to be started on any new medicine, tell your doctor, dentist or pharmacist that you are being treated with this medicine.
If you become pregnant while taking this medicine, tell your doctor immediately.
Keep all your doctor’s appointments so that your progress can be checked.
