Took Pre-employment Urine Drug Screen. Taking Methadone For Chronic Back Pain. Will That Show Positive?
elimination depends on many factors
Detailed Answer:
Hi,
Thanks for the query.
Methadone is usually metobolized in liver.
Pharmacokinetics of the methadone depends on many factors like:
-Dose and duration of the treatment
-Metabolic rate of the individual
-Cumulative effect of methadone
-Associated drug intake etc
The usual half life of methadone is 24 to 36 hours.
But depending on above factors period of it's appearance in urine differs from 2 days to 7 days.
So it is difficult to guess whether it can be detected in your urine sample or not.
Hope for the best.
