As levocetirizine hydrochloride does not enter the brain in significant amounts, it has much less sedating effect than other antihistamines. Also, studies showed that it does not significantly prolong the QT interval and has a better cardiac safety profile (R. Hulhoven, D. Rosillon et al. "Levocetirizine does not prolong the QT/QTc interval in healthy subjects: results from a thorough QT study". European Journal of Clinical Pharmacology, 2007, 63 (11): 1011–7).
