Drug Overview

Diabetic Tussin® is a maximum strength medication designed to help relieve cough and chest congestion. It contains two active ingredients: dextromethorphan HBr, which acts as a cough suppressant to temporarily relieve coughing caused by the common cold or inhaled irritants, 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 it easier for you to breathe.

This product comes in a 4 FL OZ (118 mL) bottle and is specifically formulated to provide relief from symptoms associated with respiratory conditions. If you're dealing with a cough and congestion, Diabetic Tussin® may be a helpful option to consider.
