This combination of Fexofenadine 120 mg and Montelukast 10 mg is used to provide effective relief from allergy and asthma symptoms. Fexofenadine, a non-drowsy antihistamine, helps reduce symptoms such as sneezing, runny nose, itchy or watery eyes, and itchy throat by blocking H1 histamine receptors. Montelukast, a leukotriene receptor antagonist, targets leukotrienes, substances in the body that cause inflammation, swelling, and mucus buildup in the airways. Together, this combination effectively manages allergic rhinitis and helps control mild asthma, making it ideal for those experiencing both respiratory allergies and asthma-related symptoms.
