Levton-M Tablet is a combination medication containing Levocetirizine 5mg and Montelukast 10mg, indicated for the management of allergic conditions such as allergic rhinitis and chronic urticaria. Levocetirizine, a third-generation non-sedating antihistamine, selectively inhibits peripheral H1 receptors, thereby reducing symptoms like sneezing, nasal congestion, itching, and rhinorrhea. Montelukast, a leukotriene receptor antagonist, blocks cysteinyl leukotriene receptors, mitigating bronchoconstriction, inflammation, and mucus production associated with allergic responses and asthma. The synergistic action of these agents provides comprehensive relief from allergic symptoms by targeting multiple inflammatory pathways. Levton-M is typically prescribed for patients inadequately controlled by monotherapy or those requiring concurrent management of upper and lower airway allergic manifestations. The tablet is administered orally, usually once daily in the evening, with or without food, as per physician guidance. Common adverse effects may include headache, fatigue, dry mouth, and gastrointestinal disturbances, though the combination is generally well tolerated. Caution is advised in patients with hepatic or renal impairment, and it is contraindicated in individuals with known hypersensitivity to either component. Levton-M should be used under medical supervision to ensure optimal therapeutic outcomes and minimize potential drug interactions.
