Azacitidine (Vidaza®)


Brand Name: Vidaza®

Azacitidine is used to treat myelodysplastic syndrome (MDS).

Azacitidine is a demethylation agent. In MDS, which is actually a group of conditions rather than one specific disease, the bone marrow produces misshapen blood cells and not enough healthy blood cells. Demethylation agents help restore the production of healthy blood cells and kill the abnormal cells in the marrow.

This medication comes in a powder form, which is mixed with water and then injected under the skin (subcutaneously) or into a vein (intravenously). Azacitidine is usually given once daily for 7 consecutive days, with treatment repeated every 4 weeks. Patients usually receive at least 4 treatment cycles, though your doctor may recommend additional cycles. Throughout treatment, the dose of azacitidine may be adjusted depending on how you respond to the drug and how well it’s working. An antiemetic may also be provided to help prevent nausea and vomiting that can occur following treatment with azacitidine.

Azacitidine side effects

To prevent problematic interactions between azacitidine and other drugs, be sure to tell your doctor if you are allergic to any medications, and what other medications and supplements you are currently taking. You should also inform your doctor if you have or ever had a liver tumor, liver disease, or kidney disease, if you are pregnant or planning to become pregnant, or if you are breastfeeding. Azacitidine should not be taken during breastfeeding. If you have surgery and/or dental work during your treatment, be sure to inform your doctor and/or dentist that you are taking azacitidine.
