Drug Overview

Mucus Relief DM is a medication designed to help you manage cough and chest congestion. It contains two active ingredients: dextromethorphan HBr, which acts as a cough suppressant, and guaifenesin, an expectorant that helps thin and loosen mucus. This combination works to relieve cough caused by minor throat and bronchial irritation, making your coughs more productive by clearing out bothersome mucus.

By taking Mucus Relief DM, you can temporarily reduce the intensity of your cough and the urge to cough, which can help you get a better night's sleep. It is formulated to provide relief for up to 12 hours, making it a convenient option for managing symptoms associated with the common cold or other inhaled irritants.
