What is Vidaza

Vidaza is an anticancer agent that belongs to a group of medications called “antimetabolites”. Vidaza contains the active ingredient “azacitidina”.

How is Vidaza used

Vidaza is used in adults who cannot receive a stem cell transplant to treat:

• High-risk myelodysplastic syndromes (MDS).
• Chronic myelomonocytic leukemia (CMML).
• Acute myeloid leukemia (AML).

These diseases affect the bone marrow and can cause problems in the normal production of blood cells.

How Vidaza works

Vidaza works by inhibiting the growth of cancer cells. Azacitidina is incorporated into the genetic material of cells (ribonucleic acid [RNA] and deoxyribonucleic acid [DNA]). It is believed to act by altering the way cells activate or deactivate genes by interfering with the production of new RNA and DNA. It is believed that these actions correct the problems of maturation and growth of healthy blood cells in the bone marrow that cause myelodysplastic disorders and kill cancer cells in leukemia.

Consult a doctor or nurse if you have any questions about how Vidaza works or why you have been prescribed this medication.

No use Vidaza

• If you are allergic to azacitidine or any of the other components of this medication (listed in section6).
• If you have advanced liver cancer.
• During lactation.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to use Vidaza:

• If you have a decrease in platelet, red blood cell, or white blood cell count.
• If you have kidney disease.
• If you have liver disease.
• If you have ever had heart disease or a myocardial infarction, or have a history of lung disease

Vidaza may cause a severe immune reaction called “differentiation syndrome” (see section4).

Blood tests

Before starting treatment with Vidaza and at the beginning of each treatment period (called “cycle”) blood tests will be done. This is done to check that you have a sufficient number of blood cells and that your liver and kidneys are functioning correctly.
