Drug Overview

Guaifenesin Extended-Release Tablets (1200 mg) are a type of expectorant designed to help relieve mucus and chest congestion. This medication works by loosening phlegm (mucus) and thinning bronchial secretions, making it easier for you to clear your airways and have more productive coughs.

These tablets are formulated for extended release, providing relief for up to 12 hours, and come in a maximum strength option. If you're dealing with bothersome mucus and chest congestion, Guaifenesin can help you breathe easier.
