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. This product 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.

By loosening phlegm (mucus) and thinning bronchial secretions, Mucus Relief DM makes it easier to clear mucus from your airways, leading to more productive coughs. It also helps reduce the intensity of coughing and can decrease the urge to cough, which may help you get a better night's sleep.
