I'm on Lidocaine Hydrochloride, Baclofen, Meloxicam, Oxycodone and Oxycontin. My urine came back positive for Cocaine or Benzoylecgonine.

What I had read about is that some of the Medication {Lidocaine Hydrochloride, Baclofen, Meloxicam} that I'm on, could make my urine false positive for Cocaine. I'm no Doctor, that is just what I have read on-line. I don't know WHY I can not get an answer for this.

Can someone please help? I've been to the doctor twice and take an oral drug test where they put something in my mouth with cotton as well as a urine drug test, both supervised. My test results came back showing high levels of cocaine metabolite in my oral swab, but negative in my urine. I would never do cocaine. Can anyone tell me how this is possible? I've taken a blood test that came back negative also.

I have never done cocaine but it showed up in my hair follicle test. I am on clonidine, hydrochlorothiazide, metoprolol & hydralazine for blood pressure. Plus I have a prescription Flonase nasal spray to use as needed. I have a bad knee, for which I take otc Tylenol. At one point I was taking them like 6 a day for 15 days for pain because I fell down the stairs at home. Would that cause a positive hair follicle?

I took a hair drug test and it came back positive cocaine. I never used cocaine a day in my life. I have high blood pressure and bronchitis meds I take only when needed, so I'm still wondering why I test positive of cocaine?

I had a false positive for cocaine & suboxone. A true positive benzo & methadone. I'm on methadone split dose 80x80 morning/night. I've NEVER had coke (truthfully haven't & I don't see myself better for not). I took a xanax a couple days beforehand and paid to have a breakdown retest. I was NOT positive for suboxone or coke. With suboxone obviously I would have deathly ill withdrawal bcuz the false positives were from having sex with my husband that morning before I was dropped. This IS A TRUE FACT.

It happened to me to I have been clean for 140 days from cocaine and it came back up positive for the three months I think wat u should do is pay for your own test or get it done in the programs and don't agree to it if u really didn't do it
