Drug Overview

Guaifenesin is a medication commonly used to relieve mucus and chest congestion. It acts as an expectorant, which means it helps loosen phlegm (mucus) and thin bronchial secretions, making it easier for you to cough up bothersome mucus and clear your airways. This can lead to more productive coughs and overall relief from chest congestion.

Available in 1200 mg extended-release tablets, Guaifenesin provides maximum strength relief for up to 12 hours. It is designed to help you breathe easier by thinning and loosening mucus, allowing for a more comfortable experience when dealing with respiratory issues.

Overall, it works to improve your respiratory comfort and support your body's ability to clear out mucus effectively.
