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 from losing too much fluid).
- Ask your doctor or nurse about medicine that is available to help stop or lessen the loose bowel movements.
- If you get a rash, do not put anything on it unless your doctor or nurse says you may. Keep the area around the rash clean and dry. Ask your doctor for medicine if your rash bothers you.
- Pazopanib may cause slow wound healing. It should not be given within 28 days of surgery or any test or procedure that needs conscious sedation. If you must have emergency surgery or have an accident that results in a wound, tell the doctor that you are on pazopanib. Call your cancer doctor as soon as possible for further orders.
- Take by mouth without food, at least one hour before food or two hours after food. Take with water and swallow the medicine whole. Do not chew, break or crush it.
- If you miss a dose, take it as soon as you remember. Do not take it if it is close (within 12 hours) of your next dose. Just take the next dose at your regular time. Do not take more than 1 dose at a time.
- Due to an increased risk of bleeding and wound healing problems, your cancer doctor may tell you to stop taking pazopanib before you have a surgical procedure. If you must have emergency surgery, or you have an accident that results in bleeding or a wound, tell your treating doctor that you are on pazopanib. Call your cancer doctor as soon as possible for more information.
