Accepted Answer

: Standard 10-panel test: typically looks for cocaine, marijuana, PCP, amphetamines, opiates, benzodiazepines, barbiturates, methadone, propoxyphene, &amp; Quaaludes. ETG is not part of the panel, but the testing organization could do ETG test, is asked to test for it. ETG test can be positive for 5 days after the last drink.

Question 2

why do ppl keep telling me that trazodone will show up in my 10 panel drug screen as a false positive? is there any facts to this ? i have a pre-employment 10 panel drug sreen today why is everyone saying i will test false positives for amphetamines?

Accepted Answer

: According to an article (J Anal Toxicol. 2011 Jul;35(6):364-8) The trazodone metabolite meta-chlorophenylpiperazine can cause false-positive urine amphetamine immunoassay result.

Question 3

i took a trazadone and i've heard it can cause a false positive for urine screens, i only took 50mg. how long before it's out of my urine completely?

Accepted Answer

5 x its half life: A drug is considered gone after about 5 half lives. Trazodone has a biphasic elimination with a redistribution of about one hour and an elimination of half-life of 10-12 hours. To be safe I would wait at least 50 hours and hydrate well  before taking the urine drug test. Use of trazodone a triazolopyridine antidepressant can yield a false positive amphetamine result.

Question 4

will one 100mg trazedone pill taken two weeks ago cause a false positive for methamphetamines on a ten panel urine test?

Accepted Answer

No:  Trazodone is an SSRI and should not cause a positive on the urine drug screen.  See:  https://www.drugs.com/trazodone.html

Question 5

yes it will show as a false positive in the drug screen urine test.

Question 6

if i only took trazadone once, 50mg how long before it will be out of my urine?? i heard it could cause false positive for a urine drug screen

Accepted Answer

Trazodone: This medication can cause false positives in urine drug screens but not in confirmatory testing.  If you have a prescription for this or any other medication you do not need to worry, it is when you take this or any medication that you do not have a prescription for that you run into trouble in drug tests, false positive or not.

Question 9

i take trazodone, neurontin, cymbalta, mobic, (meloxicam) robaxin, and im on an antibiotic. i tested + for benzos. can these cause a false +?

Accepted Answer

Not likely,: Unless it was a screening test only without confirmation by gas chromatogrophy and mass spectometry which is specific for the molecular structure of benzodiazepines.  If confirmed by gc/mass spec then you must have ingested a benzodiazepine.
