Fexiva-M Tablet is a combination medication containing Montelukast 10mg and Fexofenadine 120mg, designed to provide effective relief from allergic conditions such as allergic rhinitis, seasonal allergies, and chronic urticaria. Montelukast is a leukotriene receptor antagonist that works by blocking substances called leukotrienes, which cause inflammation, swelling, and constriction of airways in the respiratory tract. Fexofenadine is a second-generation antihistamine that selectively blocks peripheral H1 receptors, reducing symptoms like sneezing, itching, watery eyes, and nasal congestion without causing significant drowsiness. Together, these two active ingredients offer a dual mechanism of action, targeting both leukotriene-mediated inflammation and histamine-induced allergic responses, making Fexiva-M highly effective in managing allergy symptoms and improving quality of life. The tablet is typically taken once daily, with or without food, as prescribed by a healthcare professional. It is generally well-tolerated, but patients should inform their doctor of any existing medical conditions or medications to avoid potential interactions. Fexiva-M is not recommended for use in children under 15 years without medical advice. Always follow the prescribed dosage and consult a healthcare provider if symptoms persist or worsen.
