Topical creams relieve eczema’s itch

DEAR DOCTOR. K: I’ve had atopic eczema since I was a kid. It comes and goes. But lately the itching and dryness have gotten worse. What can I do?

DEAR READER: Eczema is a common type of skin inflammation, and about half of children with atopic eczema still have the problem as adults.

In addition to itching and dryness, parts of your skin may become red and possibly covered by tiny bumps or blisters.

Over time, areas of your skin may become thicker, scaly or flaky. You may have noticed changes in skin color, or crusty patches.

Chronic stress appears to affect the immune system in a way that makes eczema worse in some people.

There are many things you can do to prevent or reduce eczema flare-ups. Avoid exposure to: Extreme temperatures, dry air, harsh soaps, perfumed products, bubble baths.

Use blankets and clothing made of cotton. Avoid more irritating fabrics such as wool. Avoid stiff synthetics such as polyester.

After showering or bathing, pat dry (rather than rub). Then apply a moisturizing cream or lotion. Use a humidifier to add moisture to indoor air during the winter.

Sometimes eczema remains bothersome despite these steps. In that case, see your doctor. He or she may prescribe a mild- or medium-strength corticosteroid ointment or cream that you can apply to the affected areas of your skin.

Two potent and relatively new ointments and creams are tacrolimus and pimecrolimus. They have advantages over corticosteroid ointments or creams when the eczema is on the face or neck, or in folds of the skin (like the inside of the elbow).

Treatment with ultraviolet light may be another option for you.
