Drug Overview

Genexa® is a clean medicine designed to provide maximum strength relief for cough and chest congestion. It contains two key active ingredients: dextromethorphan HBr, which acts as a cough suppressant, and guaifenesin, an expectorant that helps loosen phlegm (mucus) and thin bronchial secretions. This combination works to clear your bronchial passageways of bothersome mucus, making your coughs more productive.

You can use Genexa® to temporarily relieve cough caused by minor throat and bronchial irritation, which may occur with the common cold or from inhaled irritants. It also helps reduce the intensity of coughing and the urge to cough, allowing you to get a better night's sleep. Plus, it comes in a pleasant organic blueberry flavor and contains no artificial fillers.
