The term eczema applies to any itchy rash, but it usually refers to atopic dermatitis, according to the National Eczema Association. Atopic dermatitis affects more than 30 million Americans, with 90 percent of sufferers diagnosed before the age of five. The condition causes extremely itchy, dry, raised patches on the skin that may ooze, weep or scale. Exposure to rough fabrics, heat, detergents or other irritants may trigger eczema on the arms. Treatment is with lifestyle changes and medication. Unfortunately, eczema is a persistent condition that tends to recur throughout life.
Step 1
Take short baths in lukewarm water, and avoid long, hot showers. Hot water will increase dryness and itching. Use soap only when necessary and rinse well. Pat your skin dry with a soft, clean cloth. Adding a bit of baking soda to your bathwater may help control itching and soften your skin, according to the Mayo Clinic.
Step 2
Wash clothing and bed linens in mild detergent or in only water, when possible. Harsh detergents can both trigger and worsen eczema flare-ups on the arms, according to the American Academy of Dermatology. The Mayo Clinic recommends putting all clothing and linens through an extra rinse cycle.
Step 3
Use moisturizer liberally on eczema, especially during the cold, dry winter months. Dry skin tends to make eczema worse. Apply an emollient cream within three minutes of bathing to lock moisture into the skin. The American Academy of Family Physicians (AAFP) suggests using petroleum jelly as a cheap and effective alternative to expensive moisturizing ointments. Avoid using creams and lotions containing extra ingredients or perfumes that can irritate your skin and make your eczema worse.
Step 4
Use over-the-counter antihistamines and hydrocortisone cream to control itching and inflammation. Prescription medications are available if over-the-counter products fail to relieve your symptoms. The Nemours Foundation recommends applying steroid creams directly to your arms and other affected areas twice each day. Cool compresses, wet dressings and oatmeal baths may also help relieve itching, according to the Mayo Clinic.
Step 5
Try a prescription oral steroid if your eczema is severe or accompanied by weeping. Topical immunomodulators, such as pimecrolimus and tacrolimus, may also be necessary, according to the National Eczema Society. Take antibiotics to treat any infections that develop from scratching.
Step 6
Eliminate allergic triggers to prevent and get rid of eczema on your arms. The Nemours foundation explains that pollen, mold, dander, dust, tobacco smoke, perfumes, heat, sweating, harsh fabrics and dry skin can all trigger eczema flare-ups and worsen itching and skin irritation. The AAFP recommends against wearing wool and synthetic fibers if these make your arms itchier.
Step 7
Learn coping techniques to deal with stress and anxiety. Stress can make eczema worse, according to the AAFP. Antidepressants or anti-anxiety medications may be beneficial for stress-related eczema that fails to respond to behavior therapy.
Tips and Warnings
- There may be a genetic predisposition to developing eczema, and the condition is often triggered by allergies, according to the Nemours Foundation.
