Description:

Levocetirizine (as levocetirizine dihydrochloride) is a third-generation, non-sedating antihistamine, developed from the second-generation antihistamine cetirizine. Chemically, levocetirizine is simply the isolated levorotary enantiomer of cetirizine, which is sold as a racemic mixture.

Medical uses

Levocetirizine is used for allergy symptoms including watery eyes, runny nose, sneezing, hives, and itching. The manufacturers claim it to be more effective with fewer side effects than previous second-generation drugs; however, there have been no published studies supporting this assertion. A study part-funded by the manufacturer UCB concluded it may be more effective than some other second- and third-generation anti-histamines, but did not compare it to cetirizine.
