Guaifenesin (IPA: ) (INN) or guaiphenesin (former BAN) is an expectorant drug usually taken orally to assist the expectoration ("bringing up") of phlegm from the airways in acute respiratory tract infections. Similar medicines derived from the guaiac tree were in use as a generic remedy by Native Americans when explorers reached North America in the 1500s, but guaifenesin was first approved by the Food and Drug Administration (FDA) in 1952. It is sold as pills or syrups under several brand names such as Guai-Aid, GuaiLife, Ethex 208, Humibid, Mucinex, and Robitussin. It is also included in many over-the-counter cough and cold remedies.
