Celazadine is an anti-cancer agent. This product contains a medicine called azacitidine which prevents the growth of cancer cells. Celazadine 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 this medicine works, or why this medicine has been prescribed for you.

Your doctor may have prescribed it for another reason.

Celazadine will only be prescribed to you by a doctor who has experience in medicines to treat cancers of the blood.

Tell your doctor:

If you are allergic to azacitidine or any of the other ingredients of the product 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.

Before receiving this medicine, tell your doctor if you have had any heart problems or lung disease.

You will have blood tests before you begin treatment with Celazadine 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.


Celazadine 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 nurse.

Your doctor will choose the correct dose of this medicine 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 Celazadine per m2 of body surface.

Initially, this medicine will be given daily for 7 days. 21 days later, you will have Celazadine 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.

Celazadine 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 Celazadine.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
