- Use unscented, mild soap or non-soap cleanser sparingly
- Apply an emollient immediately after bathing or showering while skin is still damp
- Avoid hot baths or showers, or those lasting more than 10 to 15 minutes which can dry the skin
- Dilute bleach baths may be recommended decrease the number of bacteria on the skin that can cause infections or worsen symptoms
- Use one-fourth to one-half cup of bleach in a full bathtub (about 40 gallons) of water and bathe 5 to 10 minutes twice weekly, followed by emollient application
- Emollients
- Wet dressings (wet wraps) to help soothe and hydrate skin, reduce itching and redness, loosen crusted areas, and prevent skin injury due to scratching
Medications used to treat eczema include:
- Over-the-counter (OTC) or prescription topical steroid creams or ointments
- Over-the-counter (OTC) or prescription oral antihistamines for itching
- Diphenhydramine (Benadryl), hydroxyzine (Vistaril, Atarax) and cyproheptadine cause drowsiness
- May be helpful for patients whose itching keeps them up at night
- Cetirizine (Zyrtec) and loratadine (Alavert, Claritin) cause less drowsiness
- Diphenhydramine (Benadryl), hydroxyzine (Vistaril, Atarax) and cyproheptadine cause drowsiness
- Oral steroids (e.g., prednisone) may be used for a short duration to treat severe flares
- Tacrolimus ointment (Protopic) and pimecrolimus cream (Elidel)
- Injectable biologics such as dupilumab (Dupixent) for adults with moderate to severe eczema that has not responded to other treatments
- Immunosuppressive drugs for patients with severe eczema who do not improve with other treatments
Ultraviolet light therapy (phototherapy) may be used to help control eczema but it is reserved for patients with severe eczema who do not respond to other treatments because it is expensive and may increase the risk of developing skin cancer.
