Overview

The mainstay of treatment for atopic dermatitis depends upon the severity of the disease and is treated with combination of conservative and medical therapy. The goals of treatment include elimination of aggravating factors, skin barrier function repair, maintaining skin hydration and pharmacologic treatment of skin inflammation.

Conservative Therapy

Elimination of exacerbating factors Maintaining skin hydration Controlling pruritus
  • Avoid trigger factors such as low humidity, overheating of skin
  • Treating stress and anxiety
  • Avoid exposure to solvents and detergents
  • Treat skin infections such as Staphylococcus aureus and herpes simplex
  • Emollients and moisturizers
    • Thick creams, ointments (eg, petroleum jelly) with low/zero water content

Medical Therapy

  • Pharmacologic medical therapies for atopic dermatitis can be classified according to the several severity scales( (i.e SCORAD index, the eczema area and severity index [EASI], and the patient-oriented eczema measure [POEM]) which includes characteristics of the rash, questions about itch, sleep, impact on daily activities, and persistence of disease.

    • Clinically uninfected skin:
      • liquid chlorine bleach-  0.5 cup or 120 ml of 6% bleach in a full bathtub [40 gallons or 150 L] of lukewarm water
  • Viral infections:
    • Herpes simplex:
      • Acyclovir 200 or 400 mg PO five times daily
      • Famciclovir 750 mg BID for one day or 1500 mg as a single dose
    • molluscum contagiosum :
      • cryotherapy, curettage, cantharidin, and podophyllotoxin as first-line therapeutic options
  • Fungal infections:
    • Dermatophyte infections- topical or oral antifungals

Controlling pruritus:

  • Preferred regimen:
