Dexfar B Syrup belongs to a class of medications called ‘expectorants’ used to treat 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, 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 your airways. 

Dexfar B Syrup is a combination of four drugs, namely: Ammonium chloride (expectorants), Diphenhydramine (antihistamine), Sodium citrate (mucolytic), and menthol (cooling agent). Ammonium chloride belongs to the class of expectorants that works by increasing the volume of fluid in the airways, reduce the stickiness of mucus, and helps to remove it from airways. Diphenhydramine belongs to the class of antihistamines (anti-allergic drugs) that works by blocking the action of histamine, a substance responsible for causing allergic reactions. Sodium citrate is a mucolytic agent (cough/sputum thinner) that works by thinning and loosening phlegm (mucus) in the lungs, windpipe, and nose. Thereby, it helps to cough out easily. Menthol is a cooling agent that produces a cooling sensation and provides relief from minor throat irritation.

Take Dexfar B Syrup as prescribed by your doctor. You are advised to take Dexfar B Syrup for as long as your doctor has prescribed it for you based on your medical condition.

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 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-colored, it indicates you may have allergies or a minor infection in the respiratory tract and yellow or green mucus indicates a respiratory infection.
