Hi, I took a 15 mg dose of methadone on Friday at 4 pm. I dont take it every day. I have a pre employment drug screen today (Monday)... Will it show up on a 10 panel since it was a low dose and I don't take it every day? I do take allergy meds, lortab (legally) and Nyquill regularly

Thanks

Ramona, Nucynta contains Tapentadol and it isn't know to cause false positives, so far, but from the various posts we've gotten on them, from all different classes of medications, I can't say that anything really surprises me, anymore.

There are, apparently, some bad tests on the market, that are causing all manner of odd results.

And also, I'd like to ask if you were taking anything else, even over the counter products?

Methadone is a synthetic opiate and it is possible that on a test that isn't done by a certified lab, other substances could cause you to show a false positive for it, including other synthetic or semi-synthetic opiates.

Few employers are required to use a certified lab and most of the regular, inexpensive labs do have an error rate that ranges fro 4 to 50%.

Sharron, in your case, it could have been the NyQuil, as it has been known to cause a false positive for Methadone on these types of tests.

It may also cause false positives for Amphetamines, Heroin and Meth.
