What is methadone?
Methadone is a painkilling medicine discovered in the 1940’s by German scientists as a substitute for morphine. Soon, American companies brought methadone to the United States for use as a painkiller and, later, to help treat persons going through heroin withdrawal. Methadone, heroin and morphine belong to a class of drugs called opioids. They all act in the brain on pain, mood and other emotions. However, methadone has some special qualities. Methadone “blocks” the effects of heroin and other opiates and reduces cravings for heroin and other opiates. It is not a treatment for any other drugs. Methadone produces no significant side effects. There are no adverse physical or mental effects from methadone. People stabilized on methadone can safely drive a car or operate machinery.
