Abstract

Adrenaline has long been the mainstay of treatment for anaphylaxis, but it is still not clear how best to give it.1 It can be administered, by intramuscular or subcutaneous injection, intravenous injection or infusion or by inhalation from an aerosol. Some of these approaches lend themselves to self administration by patients outside hospital others need to be given under direct medical supervision. This article discusses the choices.
