Allergic Skin Rash Treatment
A person with allergic dermatitis must learn how to avoid substances that trigger the illness. Treatment for allergic dermatitis usually includes skin cleansing, oral antihistamines, topical corticosteroids, and oral corticosteroids. In most cases, the symptoms of allergic dermatitis improve greatly over 2-3 days of therapy. Depending on the severity of the reaction, allergic dermatitis may be difficult to treat. Even with treatment, symptoms may last for 2-3 weeks.
Immunotherapy or allergy shots, train the body to tolerate the substance that triggers an allergic reaction. This may help reduce the severity of the symptoms when a person is exposed to the trigger.
Treatment for allergic dermatitis may include:
- Gentle skin cleansing
- Skin moisturizing:
- 5-minute lukewarm baths followed by the application of a moisturizer, such as white petrolatum
- Oral antihistamines:
- Diphenhydramine (Benadryl)
- Chlorpheniramine (Chlor-Trimeton)
- Fexofenadine (Allegra)
- Loratadine (Claritin)

- Levocetirizine (Xyzal)
