Acrivastine is a medication used for the treatment of allergies and hay fever. It is a second-generation H1-receptor antagonist antihistamine and works by blocking Histamine H1 receptors.

It is sold under the brand name Benadryl Allergy Relief in the U.K. by Pfizer, not to be confused with Benadryl Once a Day, which is cetirizine and is also sold by Pfizer in the U.K. This drug is currently not available as a generic in the U.K.^[1]

In the U.S., acrivastine is the active ingredient in the Semprex-D brand. Semprex-D is also acrivastine-based, but contains a decongestant, pseudoephedrine. Semprex-D is marketed in the U.S. by UCB, Inc..^[2]^[3]
