Drug Overview

MUCUS RELIEF DM is a medication that combines two active ingredients: dextromethorphan HBr (a cough suppressant) and guaifenesin (an expectorant). This product is designed to help you manage coughs caused by minor throat and bronchial irritation, which can occur with common colds or from inhaling irritants. It works by loosening phlegm (mucus) and thinning bronchial secretions, making it easier to clear mucus from your airways and allowing for more productive coughing.

The extended-release tablets provide maximum strength relief, helping to temporarily reduce the intensity of your cough and suppress the urge to cough, which can be particularly helpful for getting a good night's sleep.
