False Positive Methadone (Page 2)
(Newest replies first)

I am a suboxone patient, took a drug test (probably the cheap dip stick kind) and it came back positive for methadone. I haven't taken methadone for about 4 months and every drug test since then has been clean. The only things ive taken were benadryl and my subs. What can cause a false positive for methadone, and if so when they sent the remainder of my urine to the lab, it should find that i haven't taken any right? plz help.

REPORT

I have been on a Suboxone treatment plan for a year now after being on very heavy pain medications from Knee replacement and eventually amputation surgery. I have done urine tests occassionally at the docs office, however this last time it was a totally different test cup, there was no lid on it and on the boton it had a urine line and then had this strip, when the urine was in there the strip said "look for the green" there was a hint of green, I had no idea what it was. I went back to the room, waited for the doc, he came in and asked me to be honest with him, if there was anything I had done that would cause Methamphedomines show up in my urine, I was blown away, I had never done that in the past first off, and have not had any pain medication for about 6-7 months, since my last admittance to the hospital for 4 days, they made me feel like total crap. They said they were going to send my UA to a lab back east, they would not have results for about a week and from there, if it shows I have done that they will remove me from the suboxone treatment plan. This is such BS!! I came home and tried to figure out what the hell could it be. I have taken excedrin for headaches, excedrin cold and sinus, I think maybe once or twice, however I have been trying to lose weight as I am quite large, me and my daughter bought the over the counter HCG diet at walmart, that did not work so I bough Hydroxycut, I have not taken much of that either. Could any of these make my test as a false positive? I need some peace of mind with this, I feel like I am having to fight to prove myself right and this is just awful! Someone please help me. Oh- I also took Aleve.

I just tested posotive for methadone in my urine. I know for a fact it shouldnt have, i havent had any methadone for over 2yrs now. I take alot of prescriptions and until this one have never had it come back with a problem. the only new things i have taken are, pro air inhaler, soriatan, prednisone, amitriptyline and a nebulizer breathing treatment at the dr's office. i have also taken delsym and nightquil as well as a generic chest congestion for over the countres. I hope you may have an answer I really need to look into this and dont want this to appen again.

It might have been caused by the Buprenorphine in the Suboxone itself. On the cheaper tests, most semi-synthetic and synthetic opiates have been known to cause false positives for others.

The Benadryl shouldn't cause a false positive for opiates, though it can do so for other substances.

As to it being sent to the lab, the results there will really depend on how reliable the lab actually is and I have no way of knowing that.

Is there anything else I can help you with?
