Drug Overview

LEADER™ Mucus Relief DM Cough is a medication designed to help relieve coughs and manage mucus in your airways. 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 it easier for you to clear mucus from your bronchial passageways, leading to more productive coughs.

This medication is particularly useful for temporary relief of cough associated with minor throat and bronchial irritation, often due to the common cold. By controlling your cough and helping to thin mucus, LEADER™ Mucus Relief DM Cough can also assist you in getting a better night's sleep.
