My doctor has me on tramadol and here recently I have been sick and had to take cough syrup with promethazine and azithrocine. Well, I ended up having to be rushed to the hospital because, well, I don't exactly know why yet. They're saying that it is a neurological problem because my legs will not quit shaking and my heart rate shoots up to over 160 bmp. My issue is, when they did the urine test on me in Charlestion, it came back that I had PCP in my urine (Needless to say they trearted me like a dopey after words - they even sent drug councelors to my room for Christ sake!) I cried for two hours because the doctors were treating me like an addict. I've never even been in contact with PCP, so I'm wondering - does tramadol, promethazine cough syrup, or any type of antibiotc cause a false positive for PCP? P.S. I know that tramadol hasn't caused this because I've been on it since I've been 15 and am now 20.
False Positive for PCP?!?

This info came from MedScape.com: False-positive results on a quantitative drug screen for PCP vary based on the actual test used. (Consult the laboratory for a list of confounders. Reported confounders include dextromethorphan, diphenhydramine, methadone, ibuprofen, metamizol, chlorpromazine, and venlafaxine.) If contaminants are a concern gas chromatography–mass spectroscopy (GC-MS) confirmatory test can be ordered.
I would check the ingredients of the cough syrup, it might have had dextromethorphan in it.
I'm sorry for your bad experience and I hope this info helps! Lisa Z

Well thats the thing about it. I had a drug screen at the hospital (The one I was at before I was flew out) and nothing showed in my system but opiate (Which was a false poisitive caused by the tramadol). When they drug tested me in Charleston, it showed up for PCP. The second drug test they gave me showed that I had nothing what-so-ever in my urine (They were giving me loratab, adivan, and robaxan). So they acted like I wasn't taking my medicine. On the third drugs test, the nurse had to watch me uriniate. The third drug test showed the adivan and lortab (Which the hospital was giving me). Freaking weird - either someone made a big "boo boo" or I was seriously drugged lol
