Drug Overview

MUCUS RELIEF DM is a medication that combines two active ingredients: Dextromethorphan HBr, which acts as a cough suppressant, and Guaifenesin, an expectorant that helps loosen phlegm (mucus) and thin bronchial secretions. This formulation is designed to relieve coughs caused by minor throat and bronchial irritation, such as those associated with the common cold or inhaled irritants.

By thinning and loosening mucus, MUCUS RELIEF DM makes coughs more productive, helping to clear your airways. It also temporarily reduces the intensity of coughing and can help suppress the urge to cough, making it easier for you to rest and sleep.

You can use this medication to temporarily relieve coughs caused by minor throat and bronchial irritation, which can happen with the common cold or from inhaling irritants.
