Benadryl False Positive Drug Test (Top voted first)

I attend a methadone clinic in the state of pa. I've been on methadone at the same clinic for over 2 & 1/2 yrs. I've been clean since joining in may of 2011. Last Monday I had my first false/positive drug screen which came up benzos. My counsler said it's from the benadryl most likely not the Advil cold n sinus I took the night before my drug screen . Muy supervisor at the clinic was told the original lab that fulfills our drug screens at the clinic told her it wouldn't be from the benadryl. They took away my take homes while it is being sent out to be tested again. Will further testing break it down more to show that I have only took my methadone vitamins benadryl and Advil cold & sinus. I am very stressed out because I now have to wake up myself and 2yr old son at 5am to go to the clinic every day for something I didn't take. Will further testing show this?

Wow! Sounds like me I'm at a clinic for 2 years in PA as well and just had my first false positive as well, it's extremely upsetting when you know you did nothing wrong and they don't believe you especially after being clean so long. I know the lab stores the urine for about 2 weeks and they should be able to break it all down from what I understand. If not after 21/2 years you would think they would give you the benefit of the doubt. It sucks going back to square 1. I wish you the best and hope everything works out for you and you get your bottles back. Best wishes

Yess it does suck when you've been clean for almost 3 yrs and they don't give you the benefit of the doubt, but everything worked out with the retest of the UA , I didn't take benzos and I knew that but I wasn't sure how the retest worked no one at the clinic explained it to me but I was upset about the situation and them taking away my take homes while it was being retested. Everything worked out in the end.I hope everything works out for you as well and congrats on your recovery!

Yes it will show what you've taken. I came back dirty of amphetamines when I took Zantac (Ranitidine - generic for Zantac) at the methadone clinic I go to. They were going to take my take homes away too but I made then send it off and break it down. They didn't take my take homes away because it was the Ranitidine. You will get them back.

Dose benadryl make you have a false positive drug test? I've been taking benadryl for my eye and nose running and have a drug test tomorrow. Will it be affected because of the benadryl?

I am also on methadone and I have had several false positives for benzos because of benedryl. The gsmc will definitely break it down and your urine will come back clean.

Same thing happened to me. The clinic just switched labs and lots of people are claiming false positives. I know i haven't taken anything but diphenhydramine. I have to go everyday now. And they treat us like dogs. It is a hardship on me since it's 20 miles away. I know the clinic i attend (ars) has some clinics in se PA. Any chance you use one of them?

Re: rockerchick (# 3)

I've been sober on methadone for 11 yrs. Cocaine was my drug of choice. I know Xanax and Valium by brand name not by benzos. I'm in Michigan and take Benadryl due to severe issues with my nose after 2 surgeries and I refuse anymore. They do UA's, but suddenly switched to swab me not caring as it's been 11 yrs and guess what? Benzos. So I get 27 day take-homes that I worked hard to get and I may loose them for an over the counter med. I find out on the 28th but we will see then.

Wow I just had the same problem, I also go to a methadone clinic for 2 years in PA, seems kinda funny that this happened to 3 of us. Hmm I wonder if it's the same clinic. I know how frustrating it is to be accused of something you didn't do. I know cold and flu meds can give you a false positive, actually a lot of otc med can, seems we really can't take anything. From now on bring all your scripts in, even otc ones so they know. I also agree after 2years of clean urine they would give you the benefit of the doubt. I take Benadryl and I took it in with my scripts. Good luck and I hope they figure it out and you get your take homes back soon. The lab keeps your urine for about 2 weeks and they can break it down to see that it's from meds. Good luck again.
