How L Montus Flash Tablet works

L Montus Flash Tablet is a combination of two medicines: Levocetirizine and Montelukast. Together, they help relieve allergy symptoms such as sneezing and runny nose.

It works by blocking leukotriene, a chemical messenger that causes inflammation in the airways and nose. This helps reduce swelling and improves symptoms.
