Drug Overview

Guaifenesin is an expectorant, which means it helps relieve mucus buildup in your airways. Specifically, it works by loosening phlegm (mucus) and thinning bronchial secretions, making it easier for you to cough up bothersome mucus and clear your chest. This can be particularly helpful if you're experiencing chest congestion, as it promotes more productive coughing.

Available in extended-release bi-layer tablets, Guaifenesin provides both immediate and extended relief from mucus-related discomfort. It is comparable to the active ingredients found in Mucinex®, although it is not manufactured or distributed by the owner of that trademark.
