- Adults can take an over-the-counter antihistamine to relieve the discomfort of itching, provide they are not allergic to any of the ingredients. Consult a doctor before giving an antihistamine to a child.
- Take cool showers using only soaps and detergents that are made for sensitive skin. Cool compresses or Calamine lotion can be applied for additional relief, and wearing lightweight clothing that is loose-fitting will help prevent additional irritation to the rash area.
