Drug Overview

MUCUS RELIEF DM is a medication that combines two active ingredients: dextromethorphan HBr, which is a cough suppressant, and guaifenesin, an expectorant. This formulation is designed to help loosen phlegm (mucus) and thin bronchial secretions, making it easier to clear mucus from your airways and making coughs more productive.

This medication temporarily relieves cough caused by minor throat and bronchial irritation, which can occur with the common cold or from inhaled irritants. It also helps reduce the intensity of coughing and decreases the urge to cough, allowing you to rest more comfortably.
