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?
