Drug Overview

DRx CHOICE® is a maximum strength medication designed to provide relief from severe congestion and cough. It contains 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 alleviate coughs caused by minor throat and bronchial irritation, nasal congestion due to colds, and help make coughs more productive.

This medication is intended for individuals aged 12 and older and can temporarily relieve symptoms associated with the common cold or inhaled irritants, including the intensity of coughing and the impulse to cough, which can help you get to sleep.
