What are expectorants?

Expectorants are medications which help bring up mucus and other material from the lungs, bronchi and trachea1. They promote drainage of mucus from the lungs by thinning the mucus and lubricating the irritated respiratory tract1, making it easier for the lungs to do their job.

Expectorants such as guaifenesin are thought to work by stimulating receptors in the stomach, causing a reflex increase in the volume of fluid produced in the airways2. This decreases the thickness of the secretions in the airways, thus loosening phlegm and making it easier to cough up2.

Guaifenesin is the active ingredient in the BENYLIN® Wet Cough range and is used to help clear mucus or phlegm from the chest when you have congestion from a cold or flu, helping you #GetBackOutThere quickly.
