Benadryl Allergy Relief contains acrivastine, a fast-acting antihistamine used to relieve the symptoms of hay fever and other allergic conditions, such as dust mite or pet allergies. It works by blocking the effects of histamine, a substance released during an allergic reaction that causes symptoms like sneezing, runny nose, itchy eyes, and nasal congestion.

Benadryl Allergy Relief starts to work within an hour and can be taken up to three times a day for round-the-clock relief. It is a non-drowsy formula for most people, allowing you to continue daily activities while keeping allergy symptoms under control.
