False Positive For Benzodiazepines (Page 2) (Top voted first)

I have been testing positive for benzos and i cant figure out why. I have been taking suboxone & Ondansetron & promethazine. Thats it. If i fail another drug test, then my doctor is gonna kick me out. If anybody knows of any common substances, prescription or over the counter medications please inform me. Thanks

You mentioned you are taking Prozac. Prozac and other SSRIs like Zoloft and Wellbutrin can cause a false positive for benzo's on drug tests.

I work in a rehab facility and test people every day. Gabapentin will make you test positive for benzos every time.

I take gabapentin and have been testing positive for benzos for one month now. Dr. Is going to terminate if it keeps happening. I haven't done anything wrong but am going to stop the gabapentin.

Benadryl is the culprit in that string of meds

Have you been drinking energy drinks such as Monster on a daily basis by any chance? I am on a drug treatment program, and for months I kept coming up positive for benzo's on my urine drug screens and couldn't for the life of me figure out why. It had gotten to the point where I was begging my doctor to do blood work because I wasn't using anything like that. Finally after losing my carry doses, and a threat of being kicked out of the program they sent one of my positive urine screens off for more in depth testing. This is a test that can show exactly what brand of benzo is causing you to test positive. FINALLY this test came back from the second lab stating that I have ZERO benzo's in my system. From that point on 80% of every urine screen I do comes back positive in the first screen, but never the second. The only thing we can come up with for causing this false positive is energy drinks. I drink Monster energy drinks almost every day (1 can), and this has to be the culprit. If you are absolutely positive that you aren't taking benzo's then don't let yourself be kicked out of your program. Make them send your positive test on to another lab for more in depth screening.

Those 5 hour energy shots could be the culprit...... I have found out that drinking Monster energy drinks had been causing my urine screens to come back positive for benzo's. When they come back positive my clinic now sends them off for further testing to see exactly what benzo it is, and it ALWAYS comes back saying NO benzo's detected. The only medications I ever take on a daily basis is my methadone dose so the energy drinks are definitely the culprit....

Re: dee (# 12)

Benadryl is the most likely culprit there. It will show as a benzo. Also, I see you are taking a lot of herbal stuff. some of them show strange positives as well... I suggest you research all of them, but I know for sure about Benadryl.

Re: Elisabeth (# 244)

The only way to prove your innocence would be by a gas-chrotronomy test or gas-spectronomy; I forget which. it is more expensive than the simple uds, urine drug screening test, but will definitely find your culprit. Demand the gc gs testing. Take the diphenhydramine and get tested, stay off it for a week and get tested again. Then compare results...its def the diphenhydramine giving the false positive. Whoever said it's not is a fool and needs to learn how to do the below. Diphenhydramine can be quantified in blood, plasma, or serum. Gas chromatography with mass spectrometry (GC-MS) can be used with electron ionization on full scan mode as a screening test. GC-MS or GC-NDP can be used for quantification. Rapid urine drug screens using immunoassays based on the principle of competitive binding may show false-positive methadone results for people having ingested diphenhydramine. Most likely the test they are using is one of the standard 5 or 9 urine drug screens. Diphenhydramine already can cause false positives as methadone, sort of near codeine. I would assume, rightly I think, that the interaction of all of the things you are taking is making it seem to be codeine. A gs ms would definitely prove you are not taking codeine. Demand that test. But, I warn you if you did take codeine you are going to be caught. Also, this is only possible if they still have your sample showing codeine. They must test that sample with gs ms & it will show everything in your system and be specific about the amount, possible abuses, everything. Hope this helps you.

Hi everyone...im 10 days away from end of my detox for subutex due to codeine dep following major surgery. Despite my nurse knowing that in past I've tested +ve for all but cocaine, mouth swab confirming my innocence, I've
today tested +ve for benzos despite having no px for same for approx 6/12. A mouth swab was taken and again ill b proven innocent....I'm sick oof this, these results r entered into my records. and basically I'm fed up of ppl judging me surely the cost of sending a mouth swab for confirmation after a +ve urinalysis would prompt them to investigate continuous false +he's

Only two drug treatments have been pretty more successful to result in bogus good results with regard to benzodiazepines- the first substance is actually Daypro (oxaprozin) a new nonsteroidal anti-inflammatory medication (NSAID). Daypro will be the only medication effectively proven to trigger fake benefits. The state run Daypro recommending infomration claims "false-positive pee immunoassay testing assessments regarding diazepam have been noted in individuals using Daypro. The reason is , not enough specificity with the verification assessments. False-positive check benefits might be predicted stay following discontinuation involving Daypro therapy. Confirmatory exams, for example fuel chromatography/mass spectrometry (GC/MS), may identify Daypro coming from diazepam.

Keli: You mentioned a headache medicine toward the end of your post. What was it? Midrin comes to mind as a possible drug that contains in it a chemical (dichloralphenazone and isometheptene) that may cause a false positive for benzo (just a thought). First and foremost, don't (as someone else said describing his reaction when told--though i do understand the feeling!) don't go ballistic! I know how frightening it can be to suddenly have your routine for getting your pain or treatment meds all of a sudden be in a state of uncertainty!! The best, immediate response you can give to whomever told you that the test was positive is that you're more than willing to prove or do whatever it takes to clear this bogus test error.

Also very important: Valium (diazepam) is a benzo--which you know I think. Unfortunately, it's a very, very long-acting benzo--it's one of the benzo's that is not only very, very long-acting but when broken down and metabolized, also has metabolites that can be identified by blood tests. Just as an example, if you took just 10 mg of Valium, the amount (if fully absorbed) present in your blood even 200 HOURS LATER could be a shocking half (5 mg) still! Do the math; this means about 8 days later, it's still very, very present in blood--it also means that after another 8 days (so, 16 days total), there is still 2.5 mg in blood (still absolutely a failed test). So, yes--even if you took just 1 tablet, depending on your liver function, kidney function, and overall metabolism rate, just 1 or 2 tablets could lead to a test failure a month or so later, and more. Valium is arguably one of the WORST benzo's to take if you are not legitly prescribed a benzo and have to routinely be tested for controlled substances even if the test is every 4 weeks!

Jayme, I did get kicked out of my clinic for a false positive, pretty sure it was Benadryl. So, now I am on day 56, and I can't believe I actually survived. And I'm just coming off a 2mg daily dose of Suboxone. I say only to you because I hear coming off the methadone is the only thing worse. Sorry.
Your question: either the dextromethorphan or the quetiapine are your most likely culprits. Best wishes.

Yes it's the nausea medicine showing a false positive. I took the same as you and failed a few drug test because of the nausea meds. It was showing up as a benzo. When I told my Doc he said it can't be that but that was all I took besides suboxone so it had to be that. Hope this helps.
