XL-90 Plus Cough Syrup belongs to a class of medication called 'cough and cold preparations' primarily used to treat dry cough. Coughing (dry or productive) is a body's way of clearing irritants (like allergens, mucus, or smoke) from airways and preventing infection. There are two types of coughs, namely: 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 the airways. 

XL-90 Plus Cough Syrup is a combination of three drugs, namely: Chlorpheniramine maleate (antihistamine), Phenylephrine hydrochloride (decongestant), and Dextromethorphan hydrobromide (cough suppressant). Chlorpheniramine maleate works by blocking the action of histamine, a substance responsible for causing allergic reactions. Phenylephrine hydrochloride helps in shrinking the blood vessels located in the nasal passage, thereby reducing the stuffy nose. Dextromethorphan hydrobromide works by blocking the transmission of nerve signals from the cough centre in the brain to the muscles that produce cough. Together, it helps to provide relief from cough.

Cough: Coughing is a 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 up 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 infection in the respiratory tract. If you are coughing thick, solid white mucus, you may have a bacterial infection in the airways. If the mucus is clear or light-coloured, you may have allergies or a minor infection in the respiratory tract, and yellow or green mucus indicates a respiratory infection.
