Letras M Tablet is an antihistaminic medicine used in the treatment of allergies. It helps provide relief from various allergic reactions, such as cold, runny nose, sneezing, etc. An allergic reaction is a response that occurs when foreign particles enter the body. This allergic reaction may vary from person to person.

Letras M Tablet is an anti-allergic medicine containing Montelukast and Levocetirizine. Montelukast is a leukotriene antagonist, which blocks a chemical messenger (leukotriene) and reduces inflammation and swelling in the nose. Levocetirizine works by blocking the effects of a chemical messenger called ‘histamine. This chemical messenger is naturally involved in allergic reactions. Together, this medicine helps to relieve discomfort and unpleasant symptoms, like blocked/runny/itchy nose, and red/watery eyes that occur due to allergic conditions.
