How should this medicine be used?

Decitabine comes as a powder to be to be added to fluid and injected slowly over 3 hours intravenously (into a vein) by a doctor or nurse in a medical office or hospital outpatient clinic. It is usually injected every 8 hours for 3 days. This treatment period is called a cycle, and the cycle may be repeated every 6 weeks for as long as your doctor recommends. Decitabine should usually be given for at least four cycles but may be continued if your doctor decides that you will benefit from additional treatment.
Your doctor may also need to delay your treatment and reduce your dose if you experience certain side effects. Be sure to tell your doctor how you are feeling during your treatment with decitabine.
Your doctor will give you medication to prevent nausea and vomiting before you receive each dose of decitabine.
