Hi, Yes, certain antibiotics like ampicillin, amoxicillin and certain medical conditions like liver failure, kidney failure , diabetes etc can cause false positive tests for cocaine. Hope this helps. Best.

If i dont take drugs, and did a hair drug test and they found cocaine in my system a small amount, How could that be possible. Could it have anything to do with a back opperation i had and the med's that gave me??

i failed for cocaine from what i believe to be sexual intercourse or kissing, i had not used drugs in overf 7 months. they tried to tell me this isnt possible but there is no other explanation. the only medications i am on is trazadone and zoloft, besides that i take oxyElite Pro for weight loss. Is my theory correct or could my medications somehow cause the false positive urine?

I have heard that OxyElite pro can cause a false positive for amphetamines

Comment by Mason on Mon 30, Apr 2012 09:17am:
Yes, OxyElite Pro will yield a false positive on urine test for amphetamines. I just took a test 2 hours ago and they came back that I was on amphetamines. I got scared. Luckily, I had the bottle in my truck to show them what I had been taking. Once they read the label everything was okay. First thing i did afterward was google the situation and now I'm letting everyone know. Hope this helps. :)
