DRUG CLASS AND MECHANISM: Guaifenesin is an expectorant, that is, a medication that promotes elimination of mucus from the lungs. The expectorant effects of guaifenesin promote elimination of mucous by thinning the mucous and lubricating the irritated respiratory tract. Guaifenesin is an ingredient in many over-the-counter cough and cold products. Guaifenesin was first approved by the FDA in 1952.
