Skin Allergies

What is it

Skin allergies can take several forms and have a variety of causes. They can be painful, unpleasant, and frustrating. There are things you can do to treat and prevent an allergic skin reaction. The most common allergic skin conditions are:

  • Eczema
  • Hives and angioedema
  • Allergic contact dermatitis
  • Drug eruptions
  • Latex sensitivity

Skin Allergies

Symptoms

Any of these signs may mean you have a skin allergy:

  • A strange itchy or burning rash
  • Red, bumpy, scaly, or itchy skin
  • A swelling of the deeper layers of the skin, which can often include the eyelids, mouth or genitals
  • Dry, flaking skin
  • Inflamed and/or blistered skin

Skin Allergies

Eczema

A common allergic reaction often affecting the face, elbows and knees in certain patterns 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 of eczema include airborne allergens like cat dander or house dust, overheating or sweating, and contact with irritants like wool or soaps. In some individuals, emotional stress can cause a flare-up. For some patients, usually children, certain foods can also trigger eczema. Infections on the skin with staph can cause a flare-up in children as well. Eczema patients usually have very dry skin and “allergic shiners” (dark circles under the eyes) or Dennie’s lines (an extra crease 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 hypoallergenic creams or ointments is helpful; the greasier, the better.  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.

Skin Allergies

Angioedema

Hives (or urticaria) are red, itchy, raised areas of the skin that can range in size and appear anywhere on your body. Most common are acute cases, where food or drug allergies are triggers. These hives usually go away within a few days. In cases of chronic hives, people may suffer for months to years.

Angioedema is a swelling of the deeper layers of the skin that sometimes occurs with hives. Angioedema is usually not red or itchy. The areas often involved are the eyelids, lips, tongue, genitals, hands and feet.

Food or drug reactions are a common cause of acute hives and/or angioedema. Viral or bacterial infection can also trigger hives in both adults and children. Physical urticaria is hives resulting from a non-allergic source: rubbing of the skin, cold, heat, physical exertion or exercise, pressure and direct exposure to sunlight.

If the cause of your hives can be identified, you should avoid that trigger. With acute hives, some drugs or foods may take days to leave the body, so your allergist may prescribe antihistamines to relieve your symptoms until that happens.

The cause is often not identified in chronic conditions.

Skin Allergies

Contact Dermatitis

When certain substances come into contact with your skin, they may cause a delayed rash called contact dermatitis. Irritant contact dermatitis is often more painful than itchy, and is caused by a substance damaging the part of your skin it comes into contact with. The longer your skin is in contact with the substance, or the stronger the substance is, the more severe your reaction will be. These reactions appear most often on the hands and are frequently work-related.

Allergic contact dermatitis is best known by the itchy, red, blistered reaction experienced after you touch poison ivy. You can have a reaction from touching other items the plant has come into contact with as well. However, once your skin has been washed, you cannot get another reaction from touching the rash or blisters. Allergic contact dermatitis reactions can happen 24 to 48 hours after contact. Once a reaction starts, it takes 14 to 28 days to go away, even with treatment.

Nickel, perfumes, dyes, rubber (latex) products and cosmetics also frequently cause allergic contact dermatitis. Some ingredients in medications applied to the skin can cause a reaction, most commonly neomycin, an ingredient in antibiotic creams. For irritant contact dermatitis, you should avoid the substance causing the reaction. You should also avoid spilling chemicals on your skin. Gloves can sometimes be helpful. Since these reactions are non-allergic, avoiding the substance will relieve your symptoms and prevent lasting damage to your skin.

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.
