Atopic dermatitis is a long‑term inflammation of the skin (dermatitis). It results in itchy, red, swollen, and cracked skin. In children, the inner aspects of the knees and elbows are most commonly affected. In adults, the hands and feet are most commonly affected. Scratching the affected areas worsens the symptoms and increases the risk of skin infections. Many people with atopic dermatitis develop other allergic disorders such as hay fever or asthma.

The cause is unknown, but people who live in cities and dry climates are more commonly affected. Exposure to chemicals (e.g., soap) or frequent hand washing makes symptoms worse. While emotional stress can exacerbate the symptoms, it is not a cause.

Treatment involves avoiding triggers (e.g., certain soaps), applying steroid creams when flares occur, and using medications to relieve itchiness. Common aggravators include wool clothing, soaps, perfumes, dust, alcohol consumption, and cigarette smoke. Antibiotics (either oral pills or topical creams) may be needed if a bacterial infection develops.

○ Treatment ― OTC Drugs
Applying an OTC steroid to the affected area and taking an OTC antihistamine are effective; these are often the most important measures. Various moisturizers can be applied, but because atopic dermatitis involves immune dysfunction, moisturizers alone cannot resolve all issues. Washing the lesions with soap may worsen the symptoms. Allergic conditions often worsen when sleep is insufficient or stress is high.
