Drug Overview

MUCUS RELIEF DM is a medication that combines two active ingredients: Guaifenesin (1200 mg) and Dextromethorphan HBr (60 mg). It is classified as an expectorant and cough suppressant, designed to help you manage coughs and mucus. Guaifenesin works by loosening phlegm (mucus) and thinning bronchial secretions, making it easier to clear your airways. Dextromethorphan helps to temporarily relieve the urge to cough, which can be particularly helpful at night when you’re trying to sleep.

This medication provides relief for up to 12 hours, addressing coughs caused by minor throat and bronchial irritation, such as those associated with the common cold or inhaled irritants. By controlling cough and thinning mucus, MUCUS RELIEF DM aims to make your coughs more productive and less bothersome.
