Montukast-L Syrup is a combination product containing levocetirizine dihydrochloride, a histamine H1 receptor antagonist, and montelukast sodium, a leukotriene receptor antagonist. It is indicated for the treatment of symptoms associated with allergic rhinitis, including sneezing, runny nose, congestion, and itchy, watery eyes. The syrup is also indicated for the treatment of perennial allergic rhinitis and exercise-induced bronchospasm. Montelukast-L Syrup is available in a sweet-tasting, fruit-flavored syrup formulation for pediatric patients 6 months to 5 years of age. The recommended dose is 2.5 mL (10 mL/5 mL or 2.5 mL/5 mL) every 12 hours, not to exceed 5 mL in a 24-hour period. The syrup should be administered orally, using the provided measuring device, and should not be mixed with any other medications or liquids. Patients should be monitored for signs and symptoms of allergic reactions, and the medication should be discontinued if a severe reaction occurs.
