Methadone is a commonly prescribed opiate substitute treatment. Despite its common status many workers don't understand enough about methadone.


Methadone is a synthetic opiate depressant used legally as substitute treatment for opiate dependence. It can play an effective and important role in helping a person reduce the harm of their drug use and reduce the need to use illegal drugs. It produces similar effects to heroin but doesn't deliver the same degree of buzz or high. A methadone program aims to increase stability and moderate withdrawal symptoms. Methadone is only legal with a prescription but is sometimes ‘diverted’ and used illegally.


Done or The done.


In 2009, approximately 30,000 Australians were undertaking methadone treatment (National Opioid Pharmacotherapy Statistics Annual Data collection, 2009).


Varying cloloured liquid or tablet.


Ingested with cordial or fruit juice, can be diverted and injected.


Reduced physical and psychological pain, feelings of warmth, relaxation and detachment. Sweating, digestive issues, aching muscles and joints can also result. A single dose is effective for approximately 24 hours.


Shallow breathing, blue lips, and an inability to be roused or woken. An ambulance should be called if any of these symptoms occur.


Alcohol or other depressants such as benzodiazepines – compounded by the fact that street methadone can be unusually concentrated – can significantly increase the likelihood of overdose.
