Drug Overview

Mucus DM is a medication that combines two active ingredients: guaifenesin (an expectorant that helps loosen phlegm and thin bronchial secretions) and dextromethorphan hydrobromide (a cough suppressant). This formulation comes in the form of extended-release tablets designed to provide relief over a 12-hour period.

Mucus DM is primarily used to help make coughs more productive by clearing mucus from the airways and to temporarily relieve coughing caused by minor throat and bronchial irritation, such as that from the common cold or inhaled irritants. It also helps reduce the urge to cough, which can be particularly helpful for getting a good night's sleep.

Uses

This medication is designed to help you breathe easier by loosening phlegm (mucus) and thinning bronchial secretions. This action helps clear out bothersome mucus from your airways, making your coughs more productive.

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