Sometimes a skin scraping will be taken for microscopic analysis. To identify causes of allergic contact dermatitis, a doctor may try patch tests, which involves the application of suspected allergens to areas of skin on the back.
What Are the Treatments for Dermatitis?
The first steps in treating dermatitis is to identify the type of dermatitis you have and eliminate the cause, if possible.
Mild skin inflammations usually respond to over-the-counter hydrocortisone cream. To reduce inflammation and heal the irritation of most types of dermatitis, a doctor usually recommends a prescription corticosteroid cream and might prescribe an oral antihistamine to relieve severe itching. You may need an antibiotic if a secondary infection develops. Severe dermatitis may call for corticosteroid pills or injections.
In addition to medications, other treatments may be used to treat dermatitis.
