What is Eczema?
- Eczema is a chronic disease that causes dry, red, itchy, flaky skin.
- Another name for eczema is atopic dermatitis(atopic = allergic; derm = skin; itis = inflammation.)
- People with eczema have periods when the eczema is very severe and periods when the eczema is mild and well-controlled.
- When eczema is severe, the skin is very itchy. When a person itches, the skin breaks down and the eczema gets worse and worse, making it more painful and difficult to treat.

How is eczema treated?
- Avoid long baths or showers more than 10 minutes. Long bathing dries out the skin. Try to avoid very hot baths and showers.
- Moisturizing creams or ointments - to keep skin hydrated and moist. These should be applied right to skin after a short bath or shower.
- Steroid creams and ointments - these medicines are applied to the skin and tame down the inflammation. Some steroid creams are used on faces and others are not.
- Anti-itch (antihistamine) pills - This pill (or liquid) medicine is taken by mouth. For some people, these medicines help relieve the itching. The medicines do not work for everyone. Some of these medications can make you sleepy and are best for nighttime.
- Immune system medications - These medicines are prescribed by doctors for a few people with very severe cases when all other treatments have failed. These medicines tame down the immune system which plays a role in eczema.
How does a person get diagnosed with eczema?
