What is Eczema?
Eczema is one of the most common rashes we see at Treasure Valley Dermatology. In fact, nearly 30 million Americans suffer from some form of eczema. The rash appears as red scaly patches of skin and tends to be very itchy. Itch often proceeds the rash which is why eczema is commonly referred to as “the itch that rashes.” Eczema most commonly appears in childhood and goes away as a child grows older, but it can start at any point in life. More severe cases of eczema are often referred to as atopic dermatitis.
What causes eczema?
While an exact cause of eczema is not known, there are certainly genetic and environmental factors involved. Eczema is a problem with the skin barrier and it tends to run in families. In normal skin, the skin provides excellent protection to external substances that could damage or irritate the skin. In those with eczema, the skin barrier isn’t fully intact which causes increased water loss, leading to dry and irritated skin. This poor barrier also allows external substances like irritants and allergens to cause a localized immune response leading to increased inflammation and itching.
How is eczema treated?
Unfortunately there is not a definitive cure for eczema, but there are highly effective management strategies to control eczema. Fortunately, most people eventually outgrow their eczema. Treatment is focused on managing symptoms and improving the skin barrier to reduce dryness and irritation of the skin. To help those with eczema, we emphasize the following management strategies:
- Avoid hot baths or showers as these dry out the skin
- Use mild soaps such as Dove or Cetaphil
- Moisturize immediately after bathing
- Use moisturizers as often as needed throughout the day
More severe cases may require use of prescription medications to get the rash under control. We most commonly use the following treatments to manage eczema:
- Topical Steroids These topical anti-inflammatory medications are a mainstay of treatment in those with mild to moderate eczema
- Oral Antibiotics In cases where a bacterial infection is present, these may be used to clear the infection and decrease inflammation
- Oral Steroids Use of systemic anti-inflammatory medications such as prednisone are reserved for short term use in severe cases not able to be controlled with more conservative methods
- Immunomodulatory Medications In very severe cases of eczema oral medication can be used to help control the rash. Under the care of a board certified dermatologist these medications are used safely and with great success. Examples include methotrexate, cyclosporine, and Dupixient (dipilumab) which has a high success rate and few if any side effects.
