Drug Overview

Meijer Mucus Relief DM is a medication that combines two active ingredients: Dextromethorphan HBr, which acts as a cough suppressant, and Guaifenesin, an expectorant. This product is designed to help you manage coughs associated with minor throat and bronchial irritation, particularly those caused by the common cold. 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.

In addition to easing the discomfort of coughing, Meijer Mucus Relief DM can temporarily reduce the intensity of your cough and help suppress the urge to cough, which may assist you in getting a better night's sleep. This medication is available in immediate-release tablets, packaged in a bottle of 60.
