Methadone is a very strong painkiller. It is also used to treat
heroin addiction. Methadone overdose occurs when someone
accidentally or intentionally takes more than the normal or
recommended amount of this medication. Methadone overdose can
also occur if a person takes methadone with certain painkillers,
such as oxycontin, Vicodin, or morphine. This is for information
