Methadone is a synthetic opiate and it is possible that on a test that isn't done by a certified lab, other substances could cause you to show a false positive for it, including other synthetic or semi-synthetic opiates.

Few employers are required to use a certified lab and most of the regular, inexpensive labs do have an error rate that ranges fro 4 to 50%.

Sharron, in your case, it could have been the NyQuil, as it has been known to cause a false positive for Methadone on these types of tests.

It may also cause false positives for Amphetamines, Heroin and Meth.

cycleman, have you been taking anything else, including over the counter products?

i an extremly upset. I went to the doctor today and he accused me of a dirty urine having methadone in it. I have never even seen a methadone pill. I told him I am taking nucenta 75 mg. could this have registered as methadone. I am extremly hurt. I have been accused of being a liar and druggie.

Ramona, Nucynta contains Tapentadol and it isn't know to cause false positives, so far, but from the various posts we've gotten on them, from all different classes of medications, I can't say that anything really surprises me, anymore.

There are, apparently, some bad tests on the market, that are causing all manner of odd results.

And also, I'd like to ask if you were taking anything else, even over the counter products?

Hi, I took a 15 mg dose of methadone on Friday at 4 pm. I dont take it every day. I have a pre employment drug screen today (Monday)... Will it show up on a 10 panel since it was a low dose and I don't take it every day? I do take allergy meds, lortab (legally) and Nyquill regularly

Thanks

I know what you mean. i had an accident at work and had to take a drug test and it came back positive for methadone. I did't know what methadone was until the the nurse told me at the Drs. office told me. I never taken methadone, never had a prescription for it and now I don't have a job. I feel like people think i am lying. Does anybody know of any type of drugs that could cause you to have a false positive drug scheening for methadone. Thanks

I just got a positive lab test for methadone but I have never taken the drug before. I am in a treatment center that gives me meds daily and it has been showing up since I got here. My probation officer thinks i am getting this drug in my treatment center illegally somehow and this is impossible. I am currently taking sertraline, propanolo, oxcarbazepine, trazodone, cetirizine and buspirone. Can any of these or a combination of these cause a certified lab to falsely test urine for methadone?

I have been in recovery court for a year and half for drinking. I test 1 to 2 times a week and never droped dirty untill about 2 to 3 weeks ago. I have tested posititive for methadone on the 10 panal strips 3 weeks in a row at testing once a week. They labed the first one and came back positive. I have never done methadone in My life and didn't know really what it was untill I tested positive. The only thing I have done diffirent in the last year and a half is start taking birth control, wellbutrin and Ibuprophin 800 (IB p I took the whole time). The positive tests started as soon as I started taking them. I have not taken any other drugs. What could cause me to lab test positive for methidone 3 weeks in a row? It is driving me crazy to know I haven't ever in My life touched it and people think I'm full of s***. Honestly... that's what I would think. Pleas help!!!

Today my husband went into the dr o manage his seriouse neck problem and he is prescribed Percocet 7.5MG and they gave him a urine test and he tested positive for methadone, but he took only one pill 5 days prior to ehs appointment, due to serious debilitating pain and then he took sudifed PE and ibprofen for the cold he had 3 days prior to his appointment, could he just recieved a false positive from that??? I really doubt he had any methadone in his system he has such a high matabolisum, and works, eats and drinks lots of water daily. They sent the test out to be tested at the lab and I would hate to see him not get treated because of a over the counter medication. Can they tell exactly what medication it is? or is it just a catagory they use to put the nmedications in?d

I went to my doctors appointment for maintenance. I have been on suboxone for years and have stayed clean for years. About two months ago they came out with a generic suboxone so I started taking that. My copay went from $50dollars to $10. Well much to my surprise the doctor took a urine sample and I tested positive for suboxone and methodone. I have never taken methodone in my life. I felt like know one believes me. It brings back so many bad memories of the addict I once was. The lying, stealing and cheating. But I took another urine test and still positive for methodone. So I decided to go to lab cor and get a blood test. My doctor will get the results Monday or T Tuesday. It's a terrible feeling to know your telling truth and can't prove it. But I swear I have never ever taken methodone. Please help me understand this ??? Any idea's ???

Sharon, get a blood test specifically to find Methadone. If your blood work shows negative results on this site they have a list of OTC that will show many false positives. Make a copy for your doctor with all the OTC's that can change urine test. Then ask that you want your file to show this was a false positive.

I'm on compliance. I've been on suboxone now for 3 weeks. 6 weeks ago I took methadone to come off of heroin and didn't take very much. I'm a heavy person, I weigh 249lbs. I took a urine test for compliance and tested positive for methadone. Is that at all possible? I really need to know. I can go to jail if it comes back positive because I don't have a script for methadone, but I do for suboxone. Please help. I'm so worried.

Do some research that's a ridiculous statement to make. Read post #61 by "recovery now" that fairly Depicts issues involving false positives in a fair and unbiased perspective.Post's like that serves this forum community best.
MANY THANKS "RECOVERY NOW" For sharing such an insightful fair minded submission.

Sometimes this labs test with the same instruments because some are too cheap to use new ones,you can test in another place that you trust but take your test the same day your taking the other the one there sending you to take and then when you get your results you will see the place there sending you to take the test is wrong.

Hopefully this information will provide helpful information on this subject... I’m the office manager at a doctor's office. He specializes in helping people with substance abuse (his specialty is ADDICTIONOLOGY). We do urine drug screens on our patients at every visit, for many reasons; we need to be sure that the patients aren't taking anything besides is prescribed, to be sure they aren't putting themselves into danger. The DEA generally flags patients getting Suboxone and Opiates at the same time (as do the insurance companies). Also, we need to know EXACTLY what our patients are taking, so we can make sure we are giving them the correct treatment plan.

REGARDING "FALSE POSITIVES" (a substance showing up as positive on the office urine drug test that you are absolutely sure you didn't take)... Request that they send the test into the lab to "confirm" the results. The tests used in the office are usually pretty accurate, but some things may cause them to show positive incorrectly. The equipment used, when the test is sent to the lab, is MUCH more sophisticated, and MUCH more accurate. There is usually an additional charge for this (insurance will pay for it, if you have it). False positives almost NEVER happen, when tested at the lab. It’s worth the extra cost. Medical records are permanent, legal documents. They might be sent to other doctors, insurance companies, etc. They follow you where you go. I, personally, would not want a test result in my medical records that shows positive for a substance I did not take. I would like it shown that I was telling the truth when I said that no matter what the doctor's test shows, I did not take what is says I took.

One last thing (sorry, I know this is long). To be fair, doctors hear, "I didn't take _____ (whatever substance is showing up), I have no idea why it shows up positive", all day long. The tests used in their office are generally accurate, and sadly many of the people are not as truthful as they could be about their drug use. It isn't right, and I am not defending it. They are often cynical and/or don't believe you. Unfortunately, the people telling the truth are vastly outnumbered by those who are not. Doctors (the doctor I work for, at least) are not mean, are not trying to "catch you" doing something wrong, and don't mean to challenge your integrity when they seem to disbelieve you. At our office, our goal and intent is to help, support, and protect our patients.

Promethazine... usually given for nausea. I attend a suboxone clinic and I repeatedly kept failing for methadone. My doctor sent it away for a retest and it always came back as a false positive. You can not mix methadone and suboxone as they will cancel each other out and make you very very sick. After doing my own research I started recording everything I was taking for medicines that was over the counter or prescribed after failing twice. After failing 5 times for methadone I went through my notes and the only thing I had in common the time I had failed was the promethazine. Hope this helps.

From my internet searches, it seems that common sleep aids such as Benadryl (diphenhydramine) and Unisom (doxylamine succinate) and a list of other medications can create a false positive for methadone. I've never taken methadone in my life and don't even know what it looks like, but I tested positive TWICE, consecutively. I have chronic pain and terrible insomnia and especially the night before an appointment, so I was taking 1 Benadryl, 1 Unisom and a 10 mg. Melatonin tablet at bedtime. At my pain management doctor's office I had a urinalysis, but wasn't given the results until my next month's appointment. At that time I was told that I had failed, so right away was handed a cup to pee in. Since I didn't know what was going on yet and had taken those sleep meds the night before again, naturally I failed that test too. This is when I began looking for this vitally important information.
