Over-the-counter anti-itch creams, which usually have ingredients such as benzocaine, camphor, menthol and diphenhydramine, can help soothe many types of itchy skin, as reported by MedicineNet.com. Avoid scratching the area, which can irritate the skin further and increase itchiness over time.
Soothing baths are also helpful for some types of itchy skin rashes, as noted by Everyday Health. Avoid very hot water, which provides short-term relief but may ultimately worsen the itch. Cool or lukewarm water is more soothing, and you can also add oatmeal or baking soda to the water. Soak for about 20 minutes before applying a moisturizing ointment, such as petroleum jelly, to the affected area.
Cold compresses often help relieve itches, and they are fairly safe to use on a wide variety of rashes, according to MedicineNet.com. Ice packs or a washcloth soaked in cold water are easy ways to get this effect without taking a cold bath or shower.
Antihistamines can help alleviate itchy rashes caused by allergic reactions, as MedicineNet.com explains. Benadryl, Claritin and other over-the-counter medications are fairly useful for this kind of itch.
Although most itchy rashes are minor problems, they can signify more serious conditions, as reported by MedicineNet.com. If a rash develops suddenly with no apparent cause, continues to spread or does not go away within a few days, consult your doctor for treatment options.
