Uses For Nipent
Pentostatin belongs to the group of medicines called antimetabolites. It is used to treat a type of cancer of the white blood cells called hairy cell leukemia. This medicine may be used in patients with hairy cell leukemia who have already been treated with other medicines (e.g., alpha-interferon) that did not work well.
Pentostatin interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal body cells may also be affected by pentostatin, other effects may also occur. Some of these may be serious and must be reported to your doctor. Other effects may not be serious but may cause concern. Some effects may not occur for months or years after the medicine is used.
Before you begin treatment with pentostatin, you and your doctor should talk about the good this medicine will do as well as the risks of using it.
This medicine is to be administered only by or under the immediate supervision of your doctor.

While you are being treated with pentostatin, and after you stop treatment with it, do not have any immunizations (vaccinations) without your doctor's approval. Pentostatin 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.

If you cannot take these precautions, you should consider wearing a protective face mask that covers the nose and mouth.
Pentostatin can lower the number of white blood cells in your blood temporarily, increasing the chance of getting an infection (e.g., pneumonia). 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.
If you develop a skin rash or any allergic reaction to this medicine, stop using the medicine and check with your doctor as soon as possible.
