Alkof Orange Cough Syrup 100 ml belongs to the 'expectorant' class of medicine, which is primarily used to treat cough caused by mucus. Coughing (either dry or productive) is the body's way of clearing irritants (such as allergens, mucus, or smoke) from the airways and thus preventing respiratory infection. There are two types of cough: dry cough and chesty cough. A dry cough is tickly and does not produce any vicious or thick mucus, whereas a chesty cough produces mucous or sputum to help clear your airways.Disclaimer:For More Information Contact Your Physician
