False Positive For Methamphetamines (Top voted first)

Updated

I have tested false positive on the last 2 tests and all I take is equate acid reducer and equate arthritis pain with acetaminophen. Can either of those be the reason?

YES! call Zantac! The generic name of the acid reducer is ranitidine, and it causes false positives. They will confirm it for u.

I tested positive for methamphetamine. I have been taking flexeril, neurontin, promethazine and ibuprofen. Will any of these mixed together cause a positive test?

Nina, I also take flexeril, neurontin, and ibuprofen among other mess and tested positive for methamphetamine!! I have never touched the stuff and was dismissed by my pain management doctor because of this. I have heard that the combo of Flexeril and Neurontin can possibly cause this. Have you come across anything saying that?
