Decitabine (brand name Dacogen) and azacitidine (brand name Vidaza) are put directly into your bloodstream by intravenous infusion or subcutaneous injection. Your doctor establishes a schedule where you are given a certain dose over a certain number of hours for a certain number of days in a row. That's called a cycle. You then get a certain number of weeks off before starting another cycle. Sometimes it takes many cycles to see results.
I don't know the costs of these drugs. Perhaps some of the patients who take them will comment on that. There are financial assistance programs you might want to look into; see our Resources
page for some of them.
Most drug manufacturers run their own assistance programs. Celgene (Vidaza) has a Patient Support
page. EISAI Inc. (Dacogen) has the Eisai Assistance Program
