This medication is used to treat a group of blood/bone marrow disorders (myelodysplastic syndromes-MDS) in which the bone marrow does not produce enough healthy blood cells. People with MDS usually have problems such as infections, anemia, and easy bleeding/bruising. Azacitidine is a chemotherapy drug. It is believed to work by helping your bone marrow grow normal blood cells so you will need fewer blood transfusions. Azacitidine also kills abnormal blood cells that have grown too fast and do not work properly.
