Having contact dermatitis can be uncomfortable, itchy and a nuisance. Allergic contact dermatitis is caused by contact with a particular substance that one has a sensitivity to. A rash can develop within a few days or up to a week later.
Symptoms
According to the American Osteopathic College of Dermatology, persons with allergic contact dermatitis might have blistering, redness, scales or cracked skin. Dermatitis can be itchy or painful. Persons that have prolonged contact with a substance that causes contact dermatitis might find that the skin gets leathery and cracked, thick or scaly.
Identification
A doctor can perform patch testing on the skin to determine the root cause of the allergic dermatitis. The doctor will expose a small area on the skin to the suspected substances. If the area reacts with a rash, this can help to identify the culprit. Sometimes, a doctor can help to identify the reason for the dermatitis after taking a thorough history. It is important to be able to identify to the doctor substances one has come in contact with in order to help identify the cause.
Possible Reasons
Contact dermatitis can have several causes. These include plants like poison ivy and poison oak. Metals such as nickel, which can be found in zippers, buttons and jewelry are also common reasons for contact dermatitis. Rubber products such as gloves, balloons, girdles, bras and spandex can also cause contact dermatitis in some persons. Some persons can get dermatitis from coming into contact with chemicals or cleaners, such as detergents, soaps or lotions. Fragrances, hair dyes, chromium containing products are other common culprits for contact dermatitis.
Treating Dermatitis
Treatment for dermatitis begins with stopping the exposure to the substance that is causing the dermatitis. A doctor might order topical ointments containing steroids or other medication to help with decreasing the inflammation and itching. In more severe cases, a doctor can order oral medications, containing steroids, antihistamines, or other immunologic agents. Areas that have blisters or have open or cracked skin should be kept covered with gauze to prevent infection.
Prevention of Dermatitis
In order to avoid allergic contact dermatitis, avoid the substance that is causing the reaction. In cases where the affected person is not sure what is causing the dermatitis, a visit to a dermatologist can help to identify the allergen through skin testing. Substituting products is important and a dermatologist can help to identify safe products for persons with specific sensitivities.
