Management of dermatitis

Dermatitis is ideally managed once the specific form is determined. Nevertheless, there are measures that can be used to lessen the symptoms.

  • Generally, it is vital to keep the skin properly moisturized. Remember that dry skin can lead to cracks in the external layer which inhibits the barrier function of the skin. The itchiness and urge to scratch can be lessened by applying topical medications or antihistamines.
  • Avoid exposure to irritating and drying substances such as detergents or perfumes.
  • Other rashes such as fungal infections must be treated.
  • Topical steroids are often given to manage dermatitis. These drugs are available in varying strengths and can trigger side effects.
