- Do not put anything on your rash unless your doctor or nurse says you may. Keep the area around the rash clean.

Rinse your mouth with a mixture of ½ teaspoon of salt in 8 ounces of water or ½ teaspoon of baking soda (sodium bicarbonate) in 8 ounces of water. This should be done at least after very meal and at bedtime.
