FebriKast–F Syrup with a powerful formulation of Fexofenadine Hydrochloride 120 mg + Montelukast 10 mg provides effective relief from the symptoms of allergic rhinitis and other allergic conditions. Fexofenadine is a non-sedating antihistamine that blocks the action of histamine to relieve sneezing, runny nose, itching, watery eyes, and other allergy symptoms. Montelukast is a leukotriene receptor antagonist that helps reduce leukotriene-mediated inflammation and nasal congestion, providing additional relief from seasonal and perennial allergies. Together, they help control allergy symptoms, improve nasal comfort, and support better quality of life without causing significant drowsiness in most patients.
