I'm in a methadone program program, and all i was taking was benadryl, and i had a dirty urine for benzos. i paid to have it sent out for gc/ms confirmation, and it came back negative. dont listen to the i**** above who said it cant happen. ive been in the program for about a year, and was taking a lot of diphenhydramine to sleep every night. i was tested twice a week at random, and it only came up dirty once; so it does happen. it was a false positive.

Actually my methadone clinic tells us not to take nenedryl because it caises false positive drug scteens fr a few things benzodiazepines amphetamines, and pcp is what i was told and seems to be true when i looked it up

15 (FIFTEEN!!!!!) Tylenol PMs twice a day!?!!?? That is a MASSIVE overdose. Either you don't know the dose your taking, or that's a total exaggeration. If you are taking that much, you'll be in liver failure soon. Benadryl is not the only medication in that drug....Tylenol
Is the other. 3500 mg in a 24 hour period is the max safe dose. Holy crap

I tested positive for benzos and wasnt taking them and i have to somehow prove this because it has to deal with cps and my newborn son. However they are being very weird with letting me see this drug test . How do i convinve them this is a false positive and im innocent. Its very important because it has to do with my newborn son.

I just had a uds come back positive for benzos and also took benadryl the 2 nights prior to the test. I am on suboxone which i was off of for 4 days before because i had teeth removed and tylenol 3 for pain. Other than the benadryl, t 3s, suboxone, i had a toradol injection and methylphenidate in my urine. I was positive for amphetamines (from prescription methyl.), buprenorphine ( suboxone), opiates ( codeine in tylenol 3), and benzodiazapines?? I have not taken that. I believe one of these, benadryl most likely can cause false positives! I wish I knew how or how to prove.i didn't take any of them. They highly frown upon benzo use while on suboxone or methadone!

I am in the methadone program and the doctor told me not to take benadryl because it can cause a false positive for benzos. If I were you stop buying Tylenol PM. I buy generic benadryl and it only costs me 4.00 plus change for a bottle of 100 CT. I have hep c and can't take Tylenol at all. I am going to continue taking my benadryl every night because I can't sleep otherwise. And if I test positive for benzos I will just demand that it be sent out for testing. So that they can see it was a false positive.

I have been on a methadone program for almost two years and I take 15 tylenol PM's every morning and every night. So 30 total I know that's a lot so please don't say that haha...SOOO I have never been dirty EVER..the other day I had a charge on my account and I asked what it was for and they said it was for a dirty urine!! I was pissed I asked the nurse what I came up dirty for and they said Benzos. Ummmm here's the issue I don't take them...so she is sending a urine out to have it done with a GC/MS machine. Idk what else to do. But my question is what is the reality of tylenol pm causing a false positive? I just need real answers ya know. Thanks y'all!!

I never take more than 3 25mg tablets at a time.so you don't need several.however I take them very consistently and have only had 2 false positives for benzodiazepines from them in a year and a half.so it's by no means every time you take it.and it also depends on the testing done.most clinic's do a dipstick test and these are where most flaws are.Better testing has less mishaps.it comes down to if you know you didn't take anything,or think it has to be out of your system by now but u still were positive for benzodiazepines,this is one thing that will cost that and you simply demand confirmatory (re)testing of the sample.

I tested positive for benzo. Sent to the lab. It came back as ONLY serex. I don't use this or any benzos. I take oral steroid, flxerial, robaxin, naproxen, and aleve pm at night to help me sleep. Can any of these show up as serex? Please help me find a answer...

Benzos can stay in you system for over a month. I go to a methadone clinic and I still tested positive after 35 days of not taking any. My levels were really low by then though.

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
