Generic Name: Idarubicin (eye-da-ROO-bi-sin)
Trade Name: Idamycin®, Idamycin PFS®
How is this drug used? Idarubicin is FDA approved for treatment in combination with other approved products for acute myelogenous leukemia. It is important for patients to remember that physicians have the ability to prescribe medication for conditions other than those for which the drug has been approved by the FDA. Patients who have received a prescription of this drug for a condition other than which it is approved may wish to discuss this issue with their physician.
What is the mechanism of action? Idarubicin belongs to a group of drugs called anthracycline antitumor antibiotics. Idarubicin produces its anti-cancer effects by binding to DNA and inhibiting the production of proteins necessary for sustaining life of a cell.
How is idarubicin given (administered)? Idarubicin is given intravenously (into a vein) and the dose depends on several factors, including the condition being treated, the size of the patient, the particular treatment regimen being used and the overall health of the patient. If idarubicin escapes from the vein in which it is being administered, it may cause serious damage to tissues that it comes into contact with. Although patients will be monitored for this, they should tell their healthcare provider immediately if they experience pain, redness, or swelling at the site of the drug administration.
How are patients monitored? Patients will usually have scheduled meetings with their healthcare provider while they are being treated with idarubicin. Typically, blood will be drawn to check levels of blood cells and to monitor functions of some organ systems, such as the kidneys or liver. Patients may also undergo physical examinations, scans or other measures to assess side effects and response to therapy.
In addition, patients treated with idarubicin will have their heart function monitored prior to treatment and at intervals during treatment as a serious side effect that damages the heart may occur.
What are the common (occur in 30% or more of patients) side effects of treatment with idarubicin?

What are the possible late side effects of treatment with idarubicin? Patients may experience a side effect that causes damage to the heart. Although rare, this side effect causes abnormalities in the way the heart pumps blood. Patients will be monitored for this side effect and should speak with their physician about this possible late side effect.
This is not a complete list of side effects. Some patients may experience other side effects that are not listed here. Patients may wish to discuss with their physician the other less common side effects of this drug, some of which may be serious.
Some side effects may require medical attention. Other side effects do not require medical attention and may go away during treatment. Patients should check with their physician about any side effects that continue or are bothersome.
