Lasma-LC Kid Syrup 60 ml is generally used to treat allergy symptoms. The chemical messenger "histamine," which is naturally implicated in allergic reactions, is blocked by levocetirizine. It relieves allergy symptoms such sneezing, runny nose, watery eyes, itching, swelling, congestion, or stiffness. A leukotriene antagonist called montelukast lowers swelling and inflammation in the nose by blocking a chemical messenger called leukotriene. Both of them work together to lessen and alleviate allergy symptoms.Disclaimer:For more information contact your physician.
