Allergies and Itch

Allergic reactions limited to the skin including itching and hives (urticaria) usually are not life-threatening. However, difficulty breathing, wheezing, hoarseness, or difficulty swallowing may be signs of a life-threatening allergic reaction called anaphylactic shock and emergency medical services should be activated (call 911 if available) if these symptoms develop.

  • Diphenhydramine (Benadryl) is an antihistamine that treats allergic reactions and itch. It is effective but a significant side effect in drowsiness. Individuals taking diphenhydramine should not drive a car, operate heavy machinery, or drink alcohol. Nonsedating antihistamines include loratadine (Claritin), cetirizine (Zyrtec) and fexofenadine (Allegra).

  • Cromolyn sodium (Nasalcrom) is a nasal spray used to treat nasal allergies.
