Ask a Doctor and Get an Answer to Your Medical Question ASAP
This is Dr. David. I am reviewing your question now and will be with you momentarily.
yes, trazadone and venlofaxine (or effexor) is known to cause false positive urine drug testing results
I included an article about it.
any positive urine screening test, needs to be confirmed by a MS/GC confirmatory test.
if you don't use any of these drugs like MDMA or methadone, then your confirmatory testing will be negative.
yes, they can cause false positive for methadone and mdma and false positive for other agents as well.
article talks about how venlafaxine can cause false positive for methadone.
"The commonly prescribed antidepressant, trazodone, has been reported to cause false positives in 3,4-methylenedioxymethamphetamine (MDMA)"
why did you leave negative rating?
