Drug Overview

Dextromethorphan HBr and Guaifenesin is a combination medication designed to help you manage cough and chest congestion. Dextromethorphan HBr acts as a cough suppressant, temporarily relieving cough caused by minor throat and bronchial irritation, which can occur with the common cold or from inhaled irritants. Guaifenesin, an expectorant, works by loosening phlegm (mucus) and thinning bronchial secretions, making it easier to clear mucus from your airways and helping to make your coughs more productive.

This medication not only helps control coughing but also reduces the intensity of your cough, allowing you to rest better, especially at night. It is suitable for individuals aged 12 and older and comes in a pleasant Honey & Berry flavor.
