Drug Overview

MUCUS RELIEF DM COUGH is a medication designed to help alleviate coughs caused by minor throat and bronchial irritation, often associated with the common cold. 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 phlegm (mucus) and thin bronchial secretions. This combination makes coughs more productive by clearing mucus from the airways, allowing for easier breathing.

By temporarily relieving cough and helping to control coughing impulses, MUCUS RELIEF DM COUGH can assist you in getting better rest, especially when a cough disrupts your sleep.
