mitoxantrone
Mitoxantrone is a topoisomerase inhibitor, which is a type of chemotherapy. It's FDA-approved to treat multiple sclerosis (MS), prostate cancer, and acute myeloid leukemia (AML). But it's not a first-choice medication for these conditions. Mitoxantrone is given as an infusion into the veins; how often you receive it depends on your medical condition. Some common side effects of mitoxantrone include nausea and hair loss. It can also cause serious heart-related problems (cardiotoxicity). Brand name Novantrone is no longer available.
What is Mitoxantrone?
What is Mitoxantrone used for?
- Secondary progressive, progressive relapsing, or worsening relapsing-remitting multiple sclerosis (MS)
- Advanced prostate cancer that doesn't respond to hormone treatment
- Acute myeloid leukemia (AML) in adults
How Mitoxantrone works
Mitoxantrone is a topoisomerase inhibitor. It blocks proteins called topoisomerases that typically help cells make copies of themselves. By blocking these proteins, cells (including cancer cells) aren't able to grow and divide.
Mitoxantrone also affects your immune system. It's thought to slow down the worsening of MS by blocking certain immune cells from attacking your nerves.

Pharmacist tips for Mitoxantrone
- Let your provider know before you start mitoxantrone if you're taking any medications. Also let them know if you've taken heart medications or cancer medications in the past. Your provider can determine if your medications can affect your treatment or cause serious side effects.
- Your urine might have a blue-green color for 24 hours after your mitoxantrone dose. You might also experience a temporary bluish color in the whites of your eyes. This color change isn't harmful; the medication itself is a dark blue color.
- Nausea and vomiting are common side effects of mitoxantrone and can lead to dehydration. Make sure to drink plenty of fluids to stay hydrated.
- Contact your provider if you have any signs or symptoms of an infection. Your infection should be treated before or during your treatment with mitoxantrone.
- Mitoxantrone can cause myelosuppression, which is when your bone marrow makes fewer blood cells. Let your provider know immediately if you experience any signs and symptoms of myelosuppression, such as feeling tired, getting infections more often, and bruising and bleeding easily.
- Mitoxantrone can cause congestive heart failure (CHF), which happens when your heart can't pump blood the way it should. Let your provider know right away if you experience signs of heart problems, such as shortness of breath, swelling of your ankles or feet, sudden weight gain, fast heartbeat, or pounding in your chest.
- Mitoxantrone can sometimes leak out of the infusion area and cause redness, swelling, pain, burning, or a bluish skin color. The leakage can cause damage to the skin tissues. If you notice these symptoms during an infusion, alert your care team right away.
Risks and warnings for Mitoxantrone
Mitoxantrone can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Only given by an experienced provider
Mitoxantrone should only be injected slowly as an intravenous (into the vein) infusion by a healthcare provider experienced in cancer chemotherapy. This will make sure that you're monitored and treated properly for any severe side effects. This medication should never be given subcutaneously (under the skin), intramuscularly (into the muscle), intra-arterially (into an artery), or intrathecally (into the spinal canal), because it can cause serious problems.
Low blood cell count
Mitoxantrone shouldn't be given to people with a low white blood cell (WBC) count, unless it's used for the treatment of leukemia. Mitoxantrone can cause your WBCs to drop dangerously low and raise your risk for serious infection. Regardless of why you're receiving this medication, your provider will check your blood count often during treatment. Let your provider know if you have a history of low blood cell counts, and they'll determine if you should still receive this medication.
Risk of heart problems
- Risk factors: Multiple doses of mitoxantrone | History of heart disease | Radiotherapy to the lungs or heart area | Previous therapy with mitoxantrone or other medications classified as anthracyclines (e.g., doxorubicin) | Taking other medications that are harmful to the heart
Mitoxantrone can raise the risk of heart problems, such as congestive heart failure. This can happen during your treatment with mitoxantrone or months to years after stopping this medication. The more mitoxantrone you receive, the higher your risk will be for heart failure. Before starting mitoxantrone, your provider will check your heart through ultrasound to determine if you can receive this medication. If you're being treated for multiple sclerosis, your provider will check your heart before each dose, and yearly after stopping treatment.
Possible risk of leukemia (in people who have MS)
People with multiple sclerosis or cancer who receive mitoxantrone have a higher risk of developing secondary leukemia. This is when a new blood cancer develops during the treatment of a condition that you already have. The most common types are acute promyelocytic leukemia and acute myeloid leukemia. Let your provider know right away if you experience signs and symptoms of acute leukemia, such as feeling usually tired and weak, getting infections more often, bruising and bleeding easily, fever, unexplained weight loss, or night sweats.
Harm to unborn baby
- Risk factors: Pregnancy
Based on the way it works, mitoxantrone might cause harm to your unborn baby if you're getting this medication while you're pregnant. If you're a female who's able to become pregnant, speak with your provider about ways to avoid becoming pregnant and options for birth control during your treatment. You might need to take a pregnancy test before each dose to make sure you're not pregnant when you receive the medication. Discuss the risks and benefits of this medication with your provider.
Allergic reaction
Mitoxantrone contains a chemical compound called a sulfite, and although it's rare, it might cause serious allergic reactions, including anaphylaxis. You'll be monitored carefully during and after your treatment with mitoxantrone. Get medical help right away if you experience signs and symptoms of an allergic reaction, such as dizziness, hives, rash, difficulty breathing, or swelling of the mouth or throat.
