Drug Overview

WAG MS Severe Congestion and Cough is a maximum strength medication designed for individuals aged 12 and older. It combines three active ingredients: dextromethorphan HBr, which acts as a cough suppressant; guaifenesin, an expectorant that helps loosen phlegm (mucus) and thin bronchial secretions; and phenylephrine HCl, a nasal decongestant. Together, these ingredients work to relieve coughs caused by minor throat and bronchial irritation, as well as nasal and chest congestion associated with the common cold.

This medication temporarily alleviates the intensity of coughing and the impulse to cough, making it easier for you to rest. It also helps clear mucus from your airways, making coughs more productive and providing relief from congestion.
