About Montek LC Tablet
Montek LC Tablet contains Montelukast 10 mg + Levocetirizine 5 mg. This combination of two allergy medicines is used to relieve the sneezing, runny or blocked nose, and itchy, watery eyes of allergic rhinitis. Levocetirizine is an antihistamine and montelukast is a leukotriene receptor antagonist; together they act on two different chemicals the body releases during an allergic reaction. It is usually taken once a day in the evening, with or without food.
Uses of Montek LC Tablet
- Allergic rhinitis (hay fever) — seasonal or year-round

How to use
Take it exactly as your doctor prescribed, usually once a day in the evening. Swallow the tablet whole with water; it can be taken with or without food.
How it works
Levocetirizine blocks histamine, a chemical that causes sneezing, itching and a runny nose. Montelukast blocks leukotrienes, chemicals that cause swelling and congestion in the airways and nose.
