Brand Name: Generic only. No brands available.

Mitoxantrone may cause severe blood disorders, such as bone marrow suppression (which decreases your body's ability to fight infection), or cause you bruise or bleed easily. Tell your doctor if you experience fever, chills, sore throat, or unusual bruising or bleeding. Mitoxantrone may cause severe and life-threatening heart problems. Heart problems may occur during therapy or sometimes months to years after receiving mitoxantrone, and may occur even if you do not have any risk factors. Risk may increase with higher doses of mitoxantrone. Before using mitoxantrone, tell your doctor if you have a history of heart problems, radiation therapy, or treatment with anthracyclines (eg, doxorubicin), other similar medicines, or medicines that may cause heart problems. Talk to your doctor if you are unsure if any of your medicines may cause heart problems. Tell your doctor if you experience swelling of the hands or feet, shortness of breath, or sudden weight gain.

Complete blood cell counts and heart function tests may be performed to monitor for side effects.

Rarely, treatment with mitoxantrone may result in the development of a secondary cancer. Your risk may be increased if you are taking certain other cytotoxic medicines. Tell your doctor if you have a history of taking cytotoxic medicines.

Mitoxantrone is used for:

Treating acute nonlymphotcytic leukemia or advanced prostate cancer in certain patients. It is used along with other medicines(s). It may also be used for other conditions as determined by your doctor.

Mitoxantrone is an antineoplastic agent. How it works is not fully understood. It is thought to interfere with cell reproduction and growth, which helps reduce the number of cancer cells in the body.

Do NOT use mitoxantrone if:

  • you are allergic to any ingredient in mitoxantrone
  • you have multiple sclerosis along with certain heart problems

Contact your doctor or health care provider right away if any of these apply to you.
