Precautions

Drug information provided by: Merative, Micromedex®

It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly. Blood tests and tests for your heart function may be needed to check for unwanted effects.

You should not receive this medicine if you are pregnant. Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using the medicine, tell your doctor right away. Also, your doctor may require you to have a pregnancy test before you receive each dose of this medicine, to make sure you are not pregnant.

Check with your doctor right away if you are having chest pain or discomfort; fast or irregular heartbeats; shortness of breath; swelling of the feet and lower legs; or troubled breathing. These could be symptoms of a serious heart problem.

This medicine may change the color of your urine to a bluish-green color. The whites of your eyes may also appear slightly bluish-green. This is normal, especially within the first 24 hours after you receive the medicine.

While you are being treated with mitoxantrone, and after you stop treatment with it, do not have any immunizations (vaccines) without your doctor's approval. Mitoxantrone may lower your body's resistance and there is a chance you might get the infection the immunization is meant to prevent. In addition, other persons living in your household should not receive live virus vaccines (eg, nasal flu vaccine, measles, mumps, or rubella) since there is a chance they could pass the virus to you. Also, avoid persons who have received live virus vaccines. Do not get close to them and do not stay in the same room with them for very long. If you cannot take these precautions, you should consider wearing a protective face mask that covers the nose and mouth.

Mitoxantrone can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:

  • If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
  • Check with your doctor immediately if you notice any unusual bleeding or bruising; black, tarry stools; blood in the urine or stools; or pinpoint red spots on your skin.
  • Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
  • Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
  • Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
  • Avoid contact sports or other situations where bruising or injury could occur.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
