Montas-L Tablet is a combination medication indicated for the treatment of respiratory allergies and urticaria. Each tablet contains 5mg of levocetirizine, a potent H1 receptor antagonist, and 10mg of montelukast, a selective and reversible Cysteinyl Leukotriene (CysLT) receptor antagonist. Levocetirizine exhibits rapid and sustained relief from allergic symptoms such as itching, hives, and flushing, while montelukast inhibits the CysLT receptor, thereby blocking the inflammatory effects of leukotrienes. This dual action provides comprehensive relief from respiratory symptoms like wheezing, coughing, and shortness of breath, as well as skin symptoms like pruritus and angioedema. Montas-L Tablet is effective in patients with seasonal allergic rhinitis, perennial allergic rhinitis, and chronic idiopathic urticaria. The tablet is administered orally once daily, with the recommended dose being one tablet. As with all medications, potential side effects include headaches, nausea, and dizziness. Patients should consult their physician if they experience any adverse reactions or if their symptoms worsen over time.
