Drug Overview

Mucus DM is a medication that combines two active ingredients: guaifenesin (an expectorant that helps loosen phlegm) and dextromethorphan hydrobromide (a cough suppressant). This maximum strength formula is designed to help you manage coughs and mucus associated with minor throat and bronchial irritation, such as those caused by the common cold or inhaled irritants.

By loosening mucus and reducing the urge to cough, Mucus DM can make your coughs more productive and help you get a better night's sleep. The 12-hour extended-release tablets provide long-lasting relief, allowing you to feel more comfortable throughout the day and night.

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 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.

Dosage and Administration
