Treating Side Effects
- Mouth care is very important. Your mouth care should consist of gently brushing with a very soft tooth brush and rinsing your mouth with a mixture of ½ teaspoon of salt in 8 ounces of water or ½ teaspoon of sodium bicarbonate (baking soda) in 8 ounces of water. Do this at least after every meal and at bedtime.
- Avoid mouthwash that contains alcohol. Avoid alcohol and smoking because they can irritate your mouth and throat.
- Ask your doctor or nurse about medication that is available to help prevent or lessen nausea and vomiting.
- Drink 6-8 cups of fluids every day unless your doctor has told you to restrict your fluid intake due to another medical condition. A cup is 8 ounces of fluid. If you vomit or have diarrhea, you should drink more fluids so that you do not become dehydrated.
- Be careful when cooking, walking, and handling sharp objects and hot liquids.
- During the IV infusion, if you experience pain, redness, or swelling at the site of the IV infusion, please tell your nurse immediately.
- Speak with your nurse about obtaining 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 undergoing chemotherapy learn about wigs, turbans and scarves as well as makeup techniques and skin and nail care.
- Use sunscreen with SPF 30 or higher when you are outdoors even for a short time. Cover up when you are out in the sun. Wear wide-brimmed hats, long-sleeved shirts, and pants. Keep your neck, chest, and back covered.
- Avoid sun lamps, tanning booths, and tanning beds.
