Contact dermatitis is an itchy, red rash caused by repeated contact with an irritant or by coming into contact with something to which you are allergic. Examples of irritants can include soaps, detergents or chemicals. Allergens can include poison ivy, cosmetics, fabrics and latex. Contact dermatitis can be uncomfortable, but treatment can minimize these rashes.
Identification and Removal
Washing the area and removing the irritant or allergen is an important first step. Avoidance of the irritant or allergen is essential so the rash can resolve and be prevented in the future. If you are unable to identify the cause, your physician or allergist might do a skin patch test.
Creams and Medications
Corticosteroid creams are sometimes used to treat contact dermatitis. These should be used as directed by a physician and not overused, since they can cause other skin problems. Doctors sometimes recommend an antihistamine to relieve itching and inflammation. In more severe cases, systemic corticosteroids may be ordered. These usually are tapered down after a few days. Other strong creams may be ordered by a doctor in more severe cases. Creams and medications should be used under the supervision of a physician.
Home Remedies
Cool, wet compresses, cool baths with baking soda or colloidal oatmeal, wearing smooth cotton clothing and using mild soap may help reduce the discomfort of contact dermatitis. Covering the affected area in order to avoid scratching it is also recommended. Scratching can sometimes exacerbate the symptoms or break the skin and cause an infection.
Prevention
Many common sense approaches are available to prevent contact dermatitis. According to the MayoClinic.org, they include limiting contact with harsh chemicals, detergents and soaps by using gloves or rinsing promptly, using appropriate protective equipment when exposed to chemicals at work, using a barrier cream or moisturizer and using mild detergents for washing clothing.
