How Lecmon Tablet works

Lecmon 5mg/10mg Tablet is a combination of two medicines: Levocetirizine and Montelukast, which relieve sneezing and a runny nose due to allergies. Levocetirizine is an antihistamine that blocks a chemical messenger (histamine) responsible for runny nose, watery eyes, and sneezing. Montelukast is a leukotriene antagonist. It works by blocking another chemical messenger (leukotriene). This reduces inflammation (swelling) in the airways and nose, and improves symptoms.
