Treating side effects

  • Drink 6-8 cups of fluids each day unless your doctor has told you to limit your fluid intake due to some other health problem. A cup is 8 ounces of fluid. If you throw up or have loose bowel movements you should drink more fluids so that you do not become dehydrated (lack water in the body due to losing too much fluid).
  • Ask your doctor or nurse about medicine that is available to help stop or lessen nausea.
  • Vaginal lubricants can be used to lessen vaginal dryness, itching, and pain during sexual relations.

Food and drug interactions

There are known interactions of Pentostatin with food and with some other medicines like acetaminophen, aspirin, and ibuprofen.  Ask your doctor what over-the-counter (OTC) medicines you can take for fever, headache and muscle and joint pain. Patients getting this drug with carmustine, etoposide and cyclophosphamide for bone marrow transplant may have trouble breathing because of fluid build-up in the lungs.
