Drug Overview

Mucus DM is a medication that combines guaifenesin (an expectorant that helps loosen phlegm and thin bronchial secretions) and dextromethorphan hydrobromide (a cough suppressant). This maximum strength formulation is designed to help you manage coughs caused by minor throat and bronchial irritation, such as those that may occur with the common cold or from inhaled irritants.

By loosening mucus in your airways, Mucus DM makes coughs more productive, allowing you to clear out bothersome mucus more effectively. Additionally, it helps reduce the intensity of coughing and decreases the urge to cough, which can be particularly helpful for getting a good night's sleep. Each package contains 14 extended-release tablets that provide up to 12 hours of relief.

Uses

This medication is designed to help you breathe easier by loosening phlegm (mucus) and thinning bronchial secretions. By doing so, it clears out bothersome mucus from your bronchial passageways, making your coughs more productive.

You can also use this medication to temporarily relieve coughs caused by minor throat and bronchial irritation, which can happen with the common cold or from inhaling irritants. It helps reduce the intensity of your cough and can even lessen the urge to cough, making it easier for you to get a good night's sleep.
