Allergy Treatment

How can Allergy be Treated?

The best way to prevent an allergic reaction is to avoid exposure to the allergen.

Treatment and prevention of allergies involves:

  • Avoid allergens.
  • Slight reactions with mild symptoms usually respond to oral antihistamines like loratidine, cetirizine, fexofenadine or diphenhydramine.
  • Nasal corticosteroid sprays are prescribed for nasal symptoms not relieved by antihistamines.
  • Epinephrine is used in severe reactions (anaphylaxis).
  • An anti-inflammatory steroid cream such as hydrocortisone can be used for skin rashes. Small, localized skin reactions can be relieved by using a cold, wet cloth or ice for relief.
  • Patients with severe reactions may require hospitalization. In case of anaphylactic shock, other therapies are needed like oxygen for breathing difficulties or intravenous fluids to boost blood pressure.
  • Immunotherapy- Allergy shots are given to people with persistent and disruptive allergy symptoms. Allergens are injected in the body to desensitize the body's response. These shots do not treat symptoms, but they prevent future reactions by altering the immune response.
