What is atopic dermatitis?

Atopic dermatitis is a rash that usually starts in childhood. It may start out as dry, itchy skin. The rash may become very red and sore. Common places for the rash are in the elbow creases, behind the knees, on the cheeks, and on the buttocks.

The rash can come and go for years. Most children outgrow it, but some people still have it when they are adults.

You are more likely to have atopic dermatitis if a family member has it. You can't catch it from other people.

What can I do if I have it?

You can use over-the-counter creams to help with the rash and itching. Your doctor also can give you medicine. But some medicines may make your skin thinner if you use them for a long time. The rash usually gets better in 10 to 14 days if you use medicine.

How can I prevent atopic dermatitis?

It is important to use a good cream or lotion every day to keep your skin from getting dry. You can try using warm water instead of hot water during showers and baths. You should avoid activities, clothes, and foods that you know will make your skin red and itchy.
