Calamine topical (for the skin) is used to treat itching and skin irritation caused by chickenpox, insect bites or stings, measles, eczema, sunburn, poison ivy, and other minor skin conditions.
Calamine works by its counter-irritant effect. After application to the skin the calamine evaporates, which produces a cooling effect that helps distract you from the itch. This sensation also helps relieve sunburn.
