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 to reduce the urge to cough, and Guaifenesin, an expectorant that helps loosen and thin mucus in your airways. This combination works to relieve cough caused by minor throat and bronchial irritation, such as that from the common cold or inhaled irritants.

By taking Mucus Relief DM, you can experience temporary relief from coughing and chest congestion, making it easier to breathe and sleep. The extended-release tablets provide up to 12 hours of control, helping to clear mucus from your bronchial passageways and making your coughs more productive.
