Mucinex, also known by its drug name, Guaifenesin, is an over-the-counter medication used to relieve coughs and chest congestion associated with cold and flu. Some physicians recommend Mucinex to help treat symptoms of chronic obstructive pulmonary disease (COPD).
Mucinex is an expectorant, or drug that helps liquefy mucus in the lungs, making it easier to clear. Mucinex is believed to work by reducing the viscosity of mucus.
