I was given methadone almost 2 weeks ago and it was basically a one time thing and i just took a drug test at my pain management will it show up?

I was given methadone almost 2 weeks ago and it was basically a one time thing and i just took a drug test at my pain management will it show up?

Maybe: More likely to pick up the metabolite eddp. Why would you be concerned? If you are under the care of a pain management physician i would expect that they rxd the methadone. If it was not rxd for you then you using or trying the Methadone would be a warning sign for possible abuse and you should seek help. ...Read more

If I took 10 mg methadone one time on may 21 and had a 10 panel drug test taken may 29 will it come positive and when will it be out my system?

If I took 10 mg methadone one time on may 21 and had a 10 panel drug test taken may 29 will it come positive and when will it be out my system?

Depends on the: panel. There are many "10-drug" panels and they are not standardized. Some look for Methadone and some do not. A single dose of 10 mg is not likely to be present 7 days later. I am MORE concerned with your taking a drug not prescribed for you, particularly methadone. The safe starting dose in an opioid-naive patient is 2.5-5 mg. If this were not prescribed for you, don't do it again! Not safe!! ...Read more

I took 15mg methadone a week ago, will it be out of my system for a drug test only a week of my last dose? Please help. If not, how can I get it out?

Depends: If this was a one time use, it should be clear in a week, but if it was long-term it's less certain. Half-life range top is 48hrs, so you're probably good - but don't use it w/o Rx and that should satisfy a drug tester. It's good you care and use that motivation to stay clean! Best wishes. ...Read more

Depends on the test: Most blood tests are only positive for 24 hours, but urine tests can be positive for 3-4 days. Hair tests can test for drug use within the last 90 days or even longer depending on the length of your hair. I would imagine that those running the Methadone program would use both urine and blood tests to evaluate. ...Read more

How long will it take for one 10mg methadone in pill form to leave my system for drug testing and screens ?

Methadone: Methadone is one of those drugs where it's almost impossible to say when it will be completely washed out of your system - essentially because it has a ton of metabolites and a huge half life window. Could be as little as 2 days or 2 weeks. Hope that helps! ...Read more
