Allergic Reactions Rashes

Home care for an allergic rash includes:

  • Avoid contact with the substance that caused the reaction.
  • Wash your skin with a gentle soap twice a day.
  • Avoid scratching, which can cause infection.
  • Apply 1% hydrocortisone cream to the rash, such as Cortizone 10 or Cortaid Maximum Strength. Apply the cream four times a day for 10-14 days
  • Use moisturizing lotions, such as Lubriderm or Eucerin cream, to reduce itching if the skin is dry.
  • Take prescription medications as directed.
  • Nonprescription antihistamines, such as diphenhydramine, can help control itching. Adults may take 25 to 50 mg of Benadryl every four to six hours.
