Ritehist-Dm Plus Syrup is primarily used to treat dry cough. 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. 

Ritehist-Dm Plus Syrup is a combination of three drugs: Chlorpheniramine (antihistamine), Phenylephrine (decongestant) and Dextromethorphan (cough suppressant). Chlorpheniramine works by blocking the action of histamine, a substance responsible for causing allergic reactions. Phenylephrine helps shrink the blood vessels in the nasal passage, reducing a stuffy nose. Dextromethorphan works by blocking the transmission of nerve signals from the cough centre in the brain to the muscles that produce cough. Collectively, it helps to provide relief from dry 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 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.
