How BrandName works

Levocetirizine works by blocking histamine, the chemical that causes sneezing, itching, and runny nose in allergies. Montelukast stops another chemical called leukotriene, which causes swelling and tightening of airways. Together, they reduce allergy symptoms and make breathing easier in a simple, complementary way.
