Treating Side Effects
- Drink 6 to 8 cups of fluids every 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).
- Talk with your nurse about getting a wig before you lose your hair. Also, call the American Cancer Society at 800-ACS-2345 to find out information about the “ Look Good ... Feel Better” program close to where you live. It is a free program where women getting chemotherapy can learn about wigs, turbans, and scarves as well as makeup techniques and skin and nail care.
- Ask your doctor or nurse about medicine to help stop or lessen constipation, nausea, and throwing up (vomiting).
- If you are not able to move your bowels, check with your doctor or nurse before you use enemas, laxatives, or suppositories.
- Mouth care is very important. Your mouth care should consist of regular, gentle cleaning of your teeth or dentures and rinsing your mouth with a mixture of 1/2 teaspoon of salt in 8 ounces of water or ½ teaspoon of baking soda in 8 ounces of water. This should be done at least after every meal and at bedtime.
- If you have mouth sores, avoid mouthwash that contains alcohol. Avoid alcohol and smoking because they can irritate your mouth and throat.
- If you have numbness and tingling in your hands and feet, be careful when cooking, walking, and handling sharp objects and hot liquids.
