According to National Eczema Association, more than 31 millionsTrusted Sourceof Americans are suffering from some form of eczema. Eczema is a collective term describing seven types of dermatitis.

Treatment

Phototherapy treatment is usually performed over 12 to 16 weeks in treatment sessions 2 or 3 times a week.

Oral steroidsTrusted Source can be used in managing eczema that does not respond to topical steroids or as an urgent treatment for acute reactions to allergens. These are prescribed by dermatologists and are not suitable as a long-term solution due to the side effects.

Since dermatitis is an inflammatory reaction due to excessive immune response, immunosuppressantsTrusted Source are being used as a treatment for it. It comes in the form of tablets or injections. These are very strong medications and must be used under a supervision of a specialist doctor. Blood tests will be run before commencing the immunosuppressant treatment to ensure you are suitable for the drug. These will be repeated frequently throughout the course to monitor your blood count as well as liver and kidney function. Additional tests might be recommended by your health care professional.

Living with eczema

Identifying triggers, implementing a good skincare routine, and getting the right treatment are vital for managing eczema, as it can impact daily living and sleep quality. Untreated eczema can lead to inflammation and even a systemic reaction. People with chronically itchy skin can be more susceptibleTrusted Source to depression. Using low-pH skin cleansers, cold compresses, wearing soft, breathable fabrics made from natural fabrics, and moisturizing frequently can help with the itchiness.

Prevention
