Methadone overdose

Definition    Return to top

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.

Outlook (Prognosis)    Return to top

How well you do depends on the amount of poison swallowed and how quickly treatment is received. The faster you get medical help, the better the chance for recovery.

If an antidote can be given, recovery from an acute overdose begins immediately. However, since methadone's effects can last for about a day, the patient is usually kept in the hospital overnight and may receive several doses of the antidote.

The most common complications are in those who did not quickly receive the antidote. Problems can include brain damage or respiratory arrest from lack of breathing.
