Preventing the eczema itch is the main goal of treatment.

Treatment for allergic contact dermatitis depends on how severe the symptoms are. Cold soaks and compresses can offer relief for the acute, early, itchy blistered stage of your rash. You may also be prescribed topical corticosteroid creams. To prevent the reaction from returning, avoid contact with the offending substance. If you and your allergist cannot determine the substance that caused the reaction, your allergist may conduct a series of patch tests to help identify it.

Eczema
A common allergic reaction often affecting the face, elbows and knees is atopic dermatitis or eczema. This red, scaly, itchy rash is more common in young infants and those who have a personal or family history of allergy.

Common triggers include aeroallergens like cat dander or house dust, overheating or sweating, and contact with irritants like wool or soaps. In older individuals, emotional stress can cause a flare-up. For some patients, usually children, certain foods can also trigger eczema. Skin staph infections can cause a flare-up in children as well. Eczema patients usually have very dry skin and “allergic shiners” (an extra crease, called a Dennie’s line, across their lower eyelids). They are also more at risk for other skin infections.

Preventing the eczema itch is the main goal of treatment. Do not scratch or rub your rash. Applying cold compresses and creams or ointments is helpful. Also remove all irritants that aggravate your condition from your environment. If a food is identified as the cause, it must be eliminated from your diet.

Topical corticosteroid cream medications and topical calcineurin inhibitors are most effective in treating the rash. Antihistamines are often recommended to help relieve the itchiness. In severe cases, oral corticosteroids are also prescribed. If a skin staph infection is suspected to be a trigger for your eczema flare-up, antibiotics are often recommended.
