Multiple sclerosis (MS) is a disease in which the nerves of the central nervous system (brain and spinal cord) degenerate. Myelin, which provides a covering or insulation for nerves, improves the conduction of impulses along the nerves and also is important for maintaining the health of the nerves. In multiple sclerosis, inflammation causes the myelin to disappear. Consequently, the electrical impulses that travel along the nerves decelerate, that is, become slower. In addition, the nerves themselves are damaged. As more and more nerves are affected, a person experiences a progressive interference with functions that are controlled by the nervous system such as vision, speech, walking, writing, and memory.
About 350,000 people in the U.S. have multiple sclerosis. Usually, a person is diagnosed with multiple sclerosis between 20 and 50 years of age, but multiple sclerosis has been diagnosed in children and in the elderly. Multiple...

You should not use this medication if you are allergic to mitoxantrone.
If you have any of these other conditions, you may need a dose adjustment or special tests to safely use this medication:
FDA pregnancy category D. Do not use mitoxantrone without telling your doctor if you are pregnant. It could harm the unborn baby. Use effective birth control, and tell your doctor if you become pregnant during treatment.
Your doctor may want you to have a pregnancy test to make sure you are not pregnant before you receive each injection of mitoxantrone.
Mitoxantrone can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Using mitoxantrone can sometimes increase your risk of developing secondary types of leukemia. Talk to your doctor about your individual risk.
Mitoxantrone is given as an injection through a needle placed into a vein. You will receive this injection in a clinic or hospital setting. Mitoxantrone injections are usually given once every 3 months for up to 3 years. Your dose of this medication will depend on why you are receiving it and whether it causes any harmful side effects.
Tell your caregivers if you have any burning, stinging, pain, itching, redness, bruising, or swelling around the IV needle when the medicine is injected.
Mitoxantrone may cause your urine to turn a blue-green color. You may also notice a bluish discoloration of the whites of your eyes. This side effect should last only a few days and is not harmful.
Mitoxantrone can lower blood cells that help your body fight infections. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. To be sure your blood cells do not get too low, your blood will need to be tested on a regular basis. You must remain under the care of a doctor while receiving mitoxantrone.
Contact your doctor at once if you develop signs of infection such as fever, chills, sore throat, flu symptoms, easy bruising or bleeding (nosebleeds, bleeding gums), loss of appetite, nausea and vomiting, mouth sores, or unusual weakness.
Mitoxantrone can also cause serious heart damage. Your heart rate will need to be checked using an electrocardiograph or ECG (sometimes called an EKG) before and during your treatment with mitoxantrone. This machine measures electrical activity of the heart. This will help your doctor determine how long you can safely receive mitoxantrone.
The effects of mitoxantrone on your heart could be long-lasting. Your doctor may want to keep checking your heart function at yearly visits even after your mitoxantrone treatment ends. Do not miss any scheduled appointments.
