Blackbox Warning

Intravenous route (Powder for Solution)

Pentostatin should be administered under the supervision of a physician qualified and experienced in the use of cancer chemotherapeutic agents. The use of doses higher than those specified is not recommended. Dose-limiting severe renal, liver, pulmonary, and CNS toxicities occurred in Phase 1 studies that used pentostatin at higher doses (20 to 50 mg/m (2) in divided doses over 5 days) than recommended. In a clinical investigation in patients with refractory chronic lymphocytic leukemia using pentostatin at the recommended dose in combination with fludarabine phosphate, 4 of 6 patients entered in the study had severe or fatal pulmonary toxicity. The use of pentostatin in combination with fludarabine phosphate is not recommended .

Overview

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.

Proper Use

This medicine often causes nausea and vomiting. However, it is very important that you continue to receive the medicine even if you begin to feel ill. Ask your doctor for ways to lessen these effects.

You will receive this medicine while you are in a hospital or cancer treatment center. A nurse or other trained health professional will give you this medicine.

This medicine is given through a needle placed in one of your veins.

Before Using

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Drug Interactions

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are receiving this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Using this medicine with any of the following medicines is not recommended. Your doctor may decide not to treat you with this medication or change some of the other medicines you take.

Using this medicine with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.

Other Interactions

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

Other Medical Problems

The presence of other medical problems may affect the use of this medicine. Make sure you tell your doctor if you have any other medical problems, especially:

  • Infection—Pentostatin may decrease your body's ability to fight infection.
  • Kidney disease—Use with caution. The effects of pentostatin may be increased because of slower removal from the body.

Precautions

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

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.

You should not use this medicine if you are also taking fludarabine (Fludara®). Taking it together with this medicine may increase the chance of serious side effects.

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. Also, avoid persons who have taken oral polio vaccine. 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.

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.

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.
