Levocetirizine is an antihistamine that is used for alleviating symptoms of some allergies, such as watery eyes, runny nose, eye/nose itching, and sneezing. It is sometimes used to alleviate hives and scratching. It works by blocking a certain natural substance that your body produces during an allergic reaction (histamine).
Levocetirizine does not deter or prevent or treat extreme allergic reactions (such as anaphylaxis). Always bring your epinephrine injector with you if your doctor has prescribed epinephrine to treat allergic reactions. In place of epinephrine, do not try to use levocetirizine.

Previous research has shown that levocetirizine is less sedative than cetirizine and that it is equal to 5 mg of cetirizine with 2.5 mg of levocetirizine. The R-enantiomer of cetirizine is levocetirizine, and the researchers thought it would be more potent.
Levocetirizine is referred to as a non-drowsy antihistamine; in a few individuals, however, it can still induce drowsiness. Before you drive and before you use equipment or machines, ensure that your reactions are natural.
