Description

Amsacrine (AM-sah-kreen) belongs to the general group of medicines known as antineoplastics. It is used to treat acute adult leukemia.

Amsacrine interferes with the growth of cancer cells, which are then eventually destroyed by the body. Since the growth of normal body cells may also be affected by amsacrine, other effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects, like hair loss, may not be serious but may cause concern. Some effects may not occur until months or years after the medicine is used.

Before you begin treatment with amsacrine, you and your doctor should talk about the good this medicine will do as well as the risks of using it.

Amsacrine is to be administered only by or under the supervision of your doctor. It is available in the following dosage form:

• Parenteral
• Injection (Canada)

Before Using This Medicine

Children—Studies on this medicine have been done only in adult patients, and there is no specific information comparing use of amsacrine in children with use in other age groups.

Older adults—Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of amsacrine in the elderly with use in other age groups.

Proper Use of This Medicine

Precautions While Using This Medicine

It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly and to check for unwanted effects.

While you are being treated with amsacrine, and after you stop treatment with it, do not have any immunizations (vaccinations) without your doctor"s approval . Amsacrine 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 take oral polio vaccine, since there is a chance they could pass the polio virus on to you. Also, avoid persons who have taken oral polio vaccine within the last several months. 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.

Amsacrine 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 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.

If amsacrine accidentally leaks out of the vein into which it is injected, it may damage some tissues and cause scarring. Tell the doctor or nurse right away if you notice redness, pain, or swelling at the place of injection .

Side Effects of This Medicine

Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.

Less common

This medicine often causes a temporary loss of hair. After treatment with amsacrine has ended, normal hair growth should return.

Other side effects not listed above may also occur in some patients. If you notice any other effects, check with your doctor.
