Drug Overview

Mucus-DM is a maximum strength medication that combines guaifenesin (an expectorant that helps loosen phlegm) and dextromethorphan hydrobromide (a cough suppressant) in extended-release tablet form. It is designed to help you manage coughs caused by minor throat and bronchial irritation, such as those that can occur with the common cold or from inhaling irritants.

This medication works by thinning and loosening mucus in your airways, making it easier to clear out bothersome mucus and allowing for more productive coughs. Additionally, it temporarily reduces the intensity of your cough and decreases the urge to cough, which can help you get a better night's sleep.
