Drug Overview

Mucus Relief DM is a maximum strength, extended-release tablet designed to help you manage cough and mucus. It contains guaifenesin (an expectorant) which helps loosen phlegm and thin bronchial secretions, making it easier to clear mucus from your airways. Additionally, it includes dextromethorphan HBr, a cough suppressant that temporarily relieves coughing due to minor throat and bronchial irritation, which can occur with the common cold or from inhaled irritants.

This medication provides up to 12 hours of relief, helping to control the intensity of your cough and reduce the urge to cough, allowing you to rest better. Mucus Relief DM is formulated to make your coughs more productive by clearing out bothersome mucus, supporting your recovery from respiratory discomfort.
