Rexnol Syrup belongs to a class of medication called ‘cough and cold preparations’ primarily used to treat dry cough associated with a common cold or upper respiratory allergies. Coughing (dry or productive) is the body’s way of clearing irritants (like allergens, mucus, or smoke) from airways and preventing infection. There are two types of coughs: Dry cough and chesty cough. A dry cough is tickly and doesn't produce any vicious or thick mucus, while a chesty cough (wet cough) means mucous or sputum is produced to help clear your airways. 

Rexnol Syrup is a combination of two drugs: Chlorpheniramine (antihistamine) and Codeine (cough suppressant). Chlorpheniramine belongs to the class of antihistamines (anti-allergic drugs) that works by blocking the action of histamine, a substance responsible for causing allergic reactions. Codeine belongs to the class of cough suppressants that blocks the μ-opioid receptor in the brain that produces cough, thereby decreasing the urge to cough.

Cough: Coughing is the body’s way of clearing irritants (like allergens, mucus, or smoke) from airways and preventing infection. Coughs may be dry or productive. A productive cough (wet cough) brings sputum (phlegm, mucus, and other matter) from the lungs. Cough is commonly caused as a response to allergy or viral infection but coughing up mucus is possibly an indication of infection in the respiratory tract. If you are coughing thick, solid white mucus, it indicates you may have a bacterial infection in the airways. If the mucus is clear or light-coloured, it indicates you may have allergies or minor infections in the respiratory tract, and yellow or green mucus indicates a respiratory infection.
