Drug Overview

Mucinex DM is a medication designed to help you manage coughs and mucus. It works by loosening phlegm (mucus) and thinning bronchial secretions, making it easier to clear out bothersome mucus from your airways. This can lead to more productive coughs, which means you can expel mucus more effectively.

In addition to helping with mucus, Mucinex DM temporarily relieves coughs caused by minor throat and bronchial irritation, such as those that may occur with the common cold or from inhaling irritants. It can also reduce the intensity of your cough and help suppress the urge to cough, making it easier for you to get a good night's sleep.
