About Guaifenesin 400 mg Mucus Relief Tablets
Guaifenesin is an expectorant. It helps loosen phlegm (mucus) and thin bronchial secretions, so it’s easier to clear chest congestion and make coughs more productive.
Each tablet contains 400 mg of guaifenesin, with no added decongestant or cough suppressant.
