<P> Methoxyflurane has been extensively used since the 1970s in Australia as an emergency analgesic for short - term use , mostly by the Australian and New Zealand Defence Forces , and the Australian ambulance services . The drug is currently only available from one manufacturer ( Medical Developments International , Melbourne , Victoria , Australia ) . It is self - administered to children and adults using the Penthrox inhaler , a hand - held inhaler device , known as `` the green whistle '' . A non-opioid alternative to morphine , it is also easier to use than nitrous oxide . As of 2010 , methoxyflurane was listed under the Pharmaceutical Benefits Scheme for the initial management of pain due to acute trauma , as well as for brief painful procedures such as changing of wound dressings or for patient transport . A portable , disposable , single - use inhaler device ( the Penthrox inhaler ) , along with a single 3 milliliter brown glass vial of methoxyflurane is provided in doctor 's kits that allows conscious hemodynamically stable patients ( including children over the age of 5 years ) to self - administer the drug , under supervision . </P>
