- Loose bowel movements(diarrhea) that may last for a few days
- Electrolyte changes. Your blood will be checked for electrolyte changes as needed.

Treating Side Effects
- Mouth care is very important. Your mouth care should consist of routine, 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 1/2 teaspoon of baking soda in 8 ounces of water. This should be done at least after each meal and at bedtime.
- Avoid mouthwash that has alcohol. Avoid alcohol and smoking because they can bother your mouth and throat.
- Ask your doctor or nurse about medicine to help stop or lessen nausea and throwing up.
- While you are getting this drug in your vein, tell your nurse right away if you experience any pain, redness, or swelling at the site of the IV
- Drink 6-8 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 of water in the body due to losing too much fluid).
- 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.
- If you have kidney problems, your kidney function will be checked as needed.
