Xpect-D Junior Sugar Free Mixed Fruit Flavour Syrup 60 ml is used to treat dry cough. Coughing (dry or productive) is the body’s way of clearing irritants (like allergens, mucus, or smoke) from airways and preventing infection. A dry cough is tickly and doesn’t produce any viscous or thick mucus, while a chesty cough (wet cough) means mucus or sputum is created to help clear the airways.
