This question has also been asked and answered here: How long does Methadone stay in your system?

Methadone has a half-life of 24-36 hours. A drug will stay in your system for 5 half lives. Thus, it will take 120-180 hours. That is approximately 5-8 days. This is only an average, though, and it depends on your metabolism, genetic makeup, height and weight. Methadone stays in your system a very long time, which is why it's used for heroin/other opiate addicts, to taper off slowly.
