I am new to pain management and they did a urine drug test. The test showed that I had taken cocaine and meth which I have never taken in my entire life! What could cause a false positive? I've been sick with an upper respiratory infection for several weeks and have been prescribed zpack, doxycycline, levaquin, cryoheptad, antipyrine and benzocaine eardrops, oral steroids, steroid injection, Flonase, asthma inhalers, advair discus, and am on trileptal, flexeril, and other meds for fibromyalgia & trigeminal neuralgia. Can any of these meds cause a false positive?
Hi CTB, Where in the world do you get all this information??? This is really a problem tha they should address,not fair to the person thay are messing with! Hi djblynn, I just wanted you to know that I really feel for you and I am praying that this can be resolved! Take care 77grace
Thanks for your Reply!
I have worked for a lab that did drug screenings they are about 75% correct. Sometimes less. The doctor should know that there are false positives. But, sometimes Benzocaine eardrops may cause you to have a false positive for cocaine and asthma inhalers sometimes have been known sometimes to give a positive methamphetamine positive. Just ask the doctor to retest you or to split your urines in two.
