Levocetirizine Dihydrochloride + Montelukast Sodium
Levocetirizine Dihydrochloride and Montelukast Sodium is a fixed-dose combination medication. Levocetirizine is a non-sedating, long-acting second-generation antihistamine that selectively inhibits peripheral H1-receptors, reducing symptoms like sneezing, runny nose, and watery eyes. Montelukast is a selective leukotriene receptor antagonist that inhibits the cysteinyl leukotriene CysLT1 receptor, helping to reduce airway inflammation, bronchoconstriction, and nasal congestion.
Dosage by Body Weight
The standard adult dose is one tablet (Levocetirizine 5 mg + Montelukast 10 mg) taken once daily, preferably in the evening to counteract potential drowsiness. Pediatric dosing is based on age and body weight, typically administered as syrup or dispersible/chewable kid tablets. Can be taken with or without food. Do not exceed the prescribed dose.
