Pentostatin injection must be given under the supervision of a doctor who is experienced in giving chemotherapy medications for cancer.
Pentostatin may cause serious side effects, including damage to the nervous system. If you experience any of the following symptoms, call your doctor immediately: seizures; confusion; drowsiness; loss of consciousness for a period of time; pain, burning, numbness, or tingling in the hands or feet; or weakness in the arms or leg or loss of ability to move your arms or legs.
In a clinical study, people with chronic lymphocytic leukemia who used pentostatin injection along with fludarabine (Fludara) were at a higher risk of developing serious lung damage. In some cases, this lung damage caused death. Therefore, your doctor will not prescribe pentostatin injection to be given along with fludarabine (Fludara).
Pentostatin is used to treat hairy cell leukemia (cancer of a certain type of white blood cell). Pentostatin is a type of antibiotic that is only used in cancer chemotherapy. It works by slowing or stopping the growth of cancer cells in your body.
Pentostatin comes as a powder to be mixed with liquid and injected intravenously (into a vein) over 5 minutes or infused intravenously over 20 to 30 minutes by a doctor or nurse in a medical facility. It is usually injected once every other week. The length of treatment depends on how well your body responds to treatment with pentostatin.
Your doctor may need to delay your treatment or change your dose if you experience certain side effects. It is important for you to tell your doctor how you are feeling during your treatment with pentostatin injection.
Pentostatin is also sometimes used to treat chronic lymphocytic leukemia (CLL; a type of cancer of the white blood cells) and cutaneous T-cell lymphoma (a type of cancer that begins in a type of white blood cell that normally fights infection and that affects the skin). Talk to your doctor about the risks of using this medication for your condition.
