A member asked:
Will lumbar epidural shots containing lidocaine mylocaine and prilocaine with a local anesthetic show a false positive on a urine drug test?
A doctor has provided 1 answer
There are: accounts that it could show up as a false positive for cocaine on an immunoassay urine drug screen. However, you could request a GC/MS to be performed, which would definitively rule out the presence of cocaine. The best answer to your question is its extremely unlikely and not supposed to, but in theory could happen.
