Safety | A human poison by intravenous route. Human systemic effects by intravenous route: general anesthetic, heart rate change, cyanosis; by inhalation: hepatitis, nausea, fever. An experimental teratogen. Other experimental reproductive effects. A severe eye irritant. Questionable carcinogen. Human mutation data reported. Used as a clinical anesthetic. When heated to decomposition it emits very toxic fumes of F−, Cl−, and Br−. See also CHLORINATED HYDROCARBONS, ALIPHATIC; BROMIDES; and FLUORIDES. | |||

This halogenated hydrocarbon was first synthesised by C. W. Suckling of Imperial Chemical Industries (ICI) in 1951 and was first used clinically by M. Johnstone in Manchester in 1956. Use of the anesthetic was phased out during the 1980s and 1990s as newer anesthetic agents became popular. Halothane retains some use in veterinary surgery and in the Third World because of its lower cost. Halothane was given to many millions of adult and pediatric patients worldwide from its introduction in 1956 through the 1980s. By the year 2005 the common volatile anaesthetics in use were isoflurane, sevoflurane, and desflurane. Since the risk of halothane hepatitis in children was substantially lower than in adults, halothane saw continued use in pediatrics in the 1990s. However, by the year 2000 sevoflurane had largely replaced the use of halothane in children.
