Will Benadryl cause you to have a false positive for benzos?

Unfortunately that isn't true. I've taken much more than that several times daily on top of many other acetaminophen combo meds and my liver is fine. Just had it tested! I DO NOT recommend this massive intake however, for one day it will catch up... what I AM curious about is why 15 ty PM's were being injected in the morning and not specifically for putting yourself to sleep?

My husband is on parole and drug test monthly. He is clean n sober and has been for over 3 yrs..he struggles with insomnia. He was taking 2 generic Tylenol pm's each night..that's all...well an occasional extra strength Tylenol for some headaches or sore back after roofing...but he has had two test that were false positives...had to pay extra to have it analysed.. Conclusion was it's tha Tylenol PM...he said it's frustrating and annoying that he is having to pay for this and basically be accused of something he is not doing..we have tried Melatonin but it's really not phasing him much ..he sleeps for about 4/5hrs...he has got to have more sleep than that.....HELP

Taking 15 pms is very dangerous the damage it does to your liver is very unstable. ...please consider talking to your doctor about your sleep problem. ..and yes any sleep aid can cause false positives ...

They know that. If you can't add anything useful, don't add anything at all.

Re: relieved (# 10)

Absolutely correct. Just because some says they have had over 200 tests and never showed as positive for benzos DOES NOT MEAN that diphenhydramine does not flag you positive for benzos. There are alot of factors as play such as metabolism and liver function. If you ever test positive for benzos and you consume diphenhydramine, demand to have a confirmation test done. It will clear you. Diphenhydramie will sometimes show up as heroin as well. So if you have issues with benzo flase positives you might be more likely to pop for heroin. In the 10 years ive been in the methadone clinic i think ive popped positive for both benzos and heroin maybe 20 percent of the time. I have hepatitus c which may be a contributing factor. Dont let the clinic shut you out if you aren't using, demand to have a GC/MS test to clear you.

I take zoloft, and topamax. And the Zoloft is what had to be the medication that caused my false positive for benzodiazepines. I had a screen done for a job. Still waiting to hear from the owner if I get the job, but it's a rehab facility, and they didn't rescreen, or send out for further testing. I already work at a State Correctional Facility, that does random drug screens, I would not risk my job or my license as a nurse.

You would be amazed at how unreliable basic (EIA)Enzyme Immunoassay is which is the standard first pass drug test. If you take anything at all no matter how innocuous, make sure to clue in whomever is testing you.

Diphenhydramine will actually cause a false positive for methadone ..not benzodiazepines. I test positive for methadone and not benzodiazepines when I have to take 200 mg of diphenhydramine throughout the day for allergies.trust me, I'm drug screened by the Feds

Re: Spook (# 32)

Please do not claim that just because it does not happen to you that it does not happen at all. Not only does it happen, It is well documented that Diphenhydramine WILL cause false positives for Benzodiazepines; period. It is well known and documented. As I have said before there are many factors such as liver function and the presence of factors such as Hep B and C that should be taken into consideration when testing falsely positive for Benzodiazepines. Basic enzyme immunoassay (EIA) is notoriously unreliable as a first-pass positive diagnostic tool. If you test positive for Benzodiazepines and you consume anything with Diphenhydramine in it, ask for a confirmation gas chromatograph mass-spectrometer test, (GC/MS). This will hopefully vindicate you. If you know you have an upcoming urine screen try not to consume anything with Diphenhydramine the night before. If your tests are random you might want to try switching to something without Diphenhydramine. I know that some places they don't charge you for confirmation tests and some do.

Re: rach (# 18)

Look I had a false positive come up on a crap charge someone called CPS on me a few years ago, I knew for a fact I was clean. I took 2 mouth swabs back to back and both came back with same false results. I told them I wanted a hair follicle test because their test was wrong. That put all their stuff on pulse until I could get the hair test and prove my innocence. If you're really clean tell them you want that test cause theirs is false. Until that test comes back they can't try to do anything legally on your case. They can keep things how they are at the moment but as I understood it you have the right to prove your innocent and the test is wrong exspecially when it comes to your children.

Re: Tracy (# 1)

First of all, that is way too much Benadryl. Not sure why you are taking that much but that's borderline abusive. If this is an allergy issue there are many other medications that are much more effective for allergy relief that don't cause the sedation that Benadryl causes. In response to your question, Benadryl especially in high doses causes false positives for benzos and sometimes PCP. With 600 mg a day, this is definitely in the high-dose category

There is another contradicting discussion presently asking the exact same question. Fifty percent say no and the others including me say yes from my personal experience of always showing Methadone. I do not take Methadone. Maybe there are Benadryl's manufactured with different ingredients that only a Pharmacist will have that information, or ask this website. That and different tests are being given by different pain management facilities. Appeal your results but having blood work performed immediately for Methadone. If the blood work shows no Methadone give the results to your pain doctor to prove their results were a false positive. Next appointment, I would go to your PCP and ask for blood work looking for Methadone and explain why. Make sure the time frame is revealing results close to your pain physician's urine test. You will have to prove that the last test was a false positive and make them change your results to false positive, make a copy of your blood work and give pain physician a copy for your file. If you are discharged contact your State, Consumer Protection, Dept. of Health, Licensure Dept., and file a complaint. It may take a year to be resolved and you will not very likely be brought into your group. But, you do not have those results in the DATA Bank for the Federal Government. Good luck. And if you do find the other discussions concerning your questions do not engage with their conflict.

Re: Stacy (# 34)

Good for you. This a more significant measure. I do not think half of the readers on this site know what we are trying to do in educating them on appeals. They might be wanting to somehow get around the test results because they are violating their commitments regarding drug abuse. I am no longer going to argue my case. If you are not guilty of taking a drug that shows up then read what others are telling you to do to prove you are false positive, if you are bull sh--ing then stop wasting this informative post to help and advise others. Goodbye.
