Quelkof-DX Syrup Sugar Free belongs to a class of medication called 'cough and cold preparations' primarily used to treat cough due to runny nose, sneezing, and throat irritation. 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, 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) produces mucous or sputum. 

Quelkof-DX Syrup Sugar Free is a combination of two drugs, namely: Chlorphenamine maleate and Dextromethorphan hydrobromide. Chlorphenamine maleate works by blocking the action of histamine, a substance responsible for causing allergic reactions.  Dextromethorphan hydrobromide blocks the transmission of nerve signals from the cough centre in the brain to the muscles that produce cough. Together, Quelkof-DX Syrup Sugar Free helps to relieve cough, cold and allergic symptoms.

Cough: Coughing is the body's way of clearing irritants (like allergens, mucus, or smoke) from airways and preventing infection. Cough may be dry or productive. A productive cough (wet cough) brings up sputum (phlegm, mucus, and other matter) from the lungs. A dry cough does not produce any mucus or phlegm. It usually occurs due to irritation in the airways. 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.
