Uses For Vidaza

Azacitidine injection is used to treat patients with French-American-British (FAB) myelodysplastic syndrome subtypes, including refractory anemia or chronic leukemia.

Azacitidine belongs to the group of medicines called metabolites. It interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal body cells may also be affected by azacitidine, other effects will also occur. Some of these may be serious and must be reported to your doctor. Some effects may not occur for months or years after the medicine is used.

This medicine is to be given only by or under the direct supervision of your doctor.
