Drug Overview

Tussin DM is a maximum strength cough and chest congestion medication designed for individuals aged 12 and over. It contains two active ingredients: dextromethorphan HBr, which acts as a cough suppressant to help control your cough, and guaifenesin, an expectorant that helps loosen phlegm (mucus) and thin bronchial secretions, making it easier to drain your bronchial tubes.

This non-drowsy formula temporarily relieves cough caused by minor throat and bronchial irritation, which can occur with a cold, while also providing relief from chest congestion. With a pleasant raspberry and menthol flavor, Tussin DM aims to make your experience more comfortable as you manage your symptoms.

Uses

Dosage and Administration

When using this medication, it's important to follow the dosing instructions carefully. For adults and children aged 12 years and older, you should take 20 milliliters (mL) every 4 hours.
