How Long is Methadone Detected?

Detection actually indicates the period of time from last dosing of methadone. However, drug detection times for methadone are extremely variable, especially in urine testing.  The amount of time methadone metabolite remains detectable in urine greatly varies, depending on the amount and frequency of use. Following this logic, single, small methadone doses are generally detectable at a lower boundary, while chronic and long-term methadone use typically results in detection periods at the upper boundary.

Chronic users, physically inactive users, and people with a high percentage of body fat are prone to longer methadone detection periods. Additionally, individuals typically metabolize a drug faster once a tolerance to it is established. Moreover, drug detection times are also affected by the type of specimen, testing method, and cutoff levels.
