How does BENADRYL® work?

BENADRYL® products work because they contain an ingredient called diphenhydramine hydrochloride, which is an antihistamine.

Here’s what happens during an allergic reaction:

  • The body releases a substance called histamine into the bloodstream
  • Histamine travels to various parts of the body such as the eyes, nose, or skin
  • Histamine causes blood vessels to widen and expand
  • This causes redness, swelling, and inflammation
  • Symptoms of itching, sneezing, runny eyes or nose, or hives arise

The antihistamine in BENADRYL® blocks the action of histamine in the body and helps to quickly relieve the symptoms.
