Drug Overview

Guaifenesin is a medication commonly used to relieve mucus and chest congestion. It acts as an expectorant, which means it helps to thin and loosen mucus in the airways. By doing so, it makes coughs more productive, allowing you to clear bothersome mucus from your bronchial passageways more easily.

Typically available in a 400mg dosage, Guaifenesin has been effective since May 25, 2021, providing relief for those experiencing discomfort due to excess mucus. If you're dealing with chest congestion, this medication may help you breathe more comfortably.
