Which initial therapy is appropriate for a 4-month-old with atopic dermatitis presenting with itchy, dry skin and extensor papules?

• A. Wet wrap therapy
• B. Moisturizers
• C. Oral antihistamines
• D. Topical corticosteroids

Answer: (A)

In atopic dermatitis, restoring and defending the skin barrier while reducing inflammation is the first goal, especially in a young infant. Wet wrap therapy achieves that by delivering moisture to the skin and enhancing the effect of anti-inflammatory meds, which helps break the itch–scratch cycle quickly. For a 4-month-old with an active flare—itchy, dry skin and extensor papules—the skin is often dry and fragile, and rapid control of inflammation can prevent further irritation and infection. Wet wrap therapy provides a higher level of moisture and occlusion, which tightens the skin’s barrier and enhances penetration of a topical steroid when used as directed, leading to faster improvement than emollients alone. In practice, this approach is used after gentle cleansing: a liberal amount of moisturizer is applied to rehydrate, followed by an appropriate topical anti-inflammatory, and then a damp wrap with a dry layer over it to trap moisture. The wraps are typically worn for several hours or overnight and changed as recommended by a clinician. This method is particularly helpful when the dermatitis is widespread or not responding adequately to moisturizers alone, offering rapid relief while avoiding systemic therapies. While moisturizers remain foundational and topical steroids may be needed for the inflammation, the wet wrap technique targets both hydration and drug delivery to achieve quicker control of the flare in an infant.
