There are many medications that can cause false positives, far too many for me to be able to list them all here. However, if you are taking anything else, I will be happy to check them for you, if you post back with more information.

As to the Naproxen, yes, it has been known to cause false positives for THC from marijuana.


Is there anything else you'd like me to check for you?

I've been court ordered to take random drug tests i have passed them every two weeks since march with no problem but now today i was called in for a random ua it came back positive for marijuana & benzos! I haven't touched a drug since march 7 2014 but I've been taking Tylenol & naproxen for my recent allergy flare up & shoulder pain! Could either of these caused the false positive of these two(marijuana & benzos?) My custody over my children & my freedom are at stake & i need to know what might have caused this false positive

I was court ordered to take a urine drug test. I Tested positive for something called Benzo's. I take Naproxen, Tizanidine and Trazadone for back pain, carpul tunnel and insomnia. I don't take anything else. Could this be why i failed? I'm freaking out, even with a list of my medications and when i filled them at the pharmacy.

Started taking Aleve for my hip and shoulder pain. Prior to starting the Aleve my UA's all came back negative. After taking the Aleve had two UA's come back positive for bezodiaphamine, stopped taking Aleve now UA's are negitive. What's the deal?. And the company that gave the results it's not saying it's a false positive. So frustrated. My surgery is getting delayed because of this. Any way to prove my innocence????. Thanks
