Drug Overview

MUCUS RELIEF DM is a medication designed to help alleviate cough and relieve congestion. It contains two active ingredients: Guaifenesin, which is an expectorant that helps loosen phlegm (mucus) and thin bronchial secretions, making it easier to clear mucus from your airways. The other ingredient, Dextromethorphan HBr, acts as a cough suppressant, temporarily relieving the urge to cough, especially during the night, so you can get better rest.

This extended-release tablet is particularly useful for managing coughs caused by minor throat and bronchial irritation, such as those that may occur with the common cold or from inhaled irritants. By thinning and loosening mucus, MUCUS RELIEF DM helps make your coughs more productive, allowing you to breathe more comfortably.
