Idarubicin is a chemotherapy medicine that damages the genes of leukemia cells so they cannot grow.
What it is
Idarubicin slips into the genetic code (DNA) of the cell. It blocks a protein the cell needs to copy its DNA. The leukemia cell cannot divide and dies.
Often used for
- acute myeloid leukemia in adults
How you get it
Idarubicin is given through a vein (IV), usually in the hospital. It takes about 10 to 15 minutes. It is often given once a day for 3 days, along with another chemotherapy called cytarabine. Your schedule may be different.
Common side effects and what helps
- Very low blood counts for a few weeks. You may need blood or platelet transfusions.

- Upset stomach or throwing up. Take nausea medicine as your team tells you.
- Mouth sores. Rinse often with a mild salt water or baking soda rinse.
- Diarrhea. Drink plenty of fluids.
