Drug Overview

Medique® Medi-Mucus is a combination medication designed to help relieve coughs and clear mucus from your airways. It contains dextromethorphan HBr, which acts as a cough suppressant, and guaifenesin, an expectorant that helps loosen phlegm (mucus) and thin bronchial secretions. This makes it easier for you to cough up bothersome mucus, leading to more productive coughs.

You can use Medique® Medi-Mucus to temporarily relieve coughs caused by minor throat irritations, such as those that may occur with the common cold or from inhaling irritants. It also helps reduce the intensity of coughing and can help you get better sleep by minimizing the urge to cough.
