Brozedex Sugar Free Syrup is used to treat cough associated with mucus. Coughing (dry or productive) is the body’s way of clearing irritants (like allergens, mucus or smoke) from airways, thereby preventing respiratory infection. Cough has two types: dry cough and chesty cough. A dry cough means it's tickly and doesn't produce any vicious or thick mucus, while a chesty cough means mucous or sputum is produced to help clear your airways.
