The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. The patient may receive:

• Fluids by IV
• Laxative
• Medicines to treat symptoms
• Activated charcoal
• Narcotic antagonist -- medicine (antidote) to reverse the effect of the poison
• A nasogastric (NG) tube thru the nose into the stomach to empty the stomach ( gastric lavage)

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 received the antidote. Problems can include brain damage from lack of breathing or death from not breathing (respiratory arrest).
