Why Did Methadone Not Show Up In Urine Test (Top voted first)

Updated

I am very concerned. My Dr. started me on methadone at 5 mg 2x per day. 4 days later I had a urine test and the methadone did not show up. now my Dr. is concerned that I am not following treatment and I have been following it as I was told to. does anyone have have any idea as to why methadone would not show up in a pee test?

Be careful. There are some doctors out there doing this to their patients and I am hearing about a lot lately. Make sure you get the lab records, as my brother had to do because this was happening to him and his doctor refused to see him anymore for his chronic pain. He found out through his lab records and having another one of his doctors' give him a screening to find out that his Doctor was not even testing him for that med, purposely. Never the less, make sure it is not because your Dr is weary of you and only looking out for himself and his license by harming you and your health. Only a suggestion.....

the dose is too low. it has to have a concentraction in the urine of at least 300ng/ml for most test to be accurate. and because it is expensive to test for lower levels than that it is not done. your dose is not high enough to be detected and that is why it is not showing up. you dr. should know this if he is a specialist in pain management or knows anything about methadone. it is unlike anyother opiate in the way it is broken down by the body and the way it works in the body

Yeah 5mg is too little. you'll metabolize that overnight no probs. If your Doctor thinks your selling it and not taking it, then tell him, that another Doctor (me) said that 5mg is so small it will not show up in a standard urinalysis. It will show up in a GCMS urinalysis so tell your Doctor you want the Advanced GCMS (Gas chromatography Mass Spectrometer. But hes a Heads up warning. You cant beat this. This will show the tiniest of tiny amounts of anything. It can tell how much water you flushed with, enabling Pathologists to simply apply a math algorithm to determine the actual drug amount etc. It is so accurate that if somebody blew a single paper Marijuana joint in the same room as you it will show up those very small amounts. If you want to prove to your doctor when you stopped / Started illicit drugs ask for a hair follicle test to show your drug use in a time line.. But basically it is possible to metabolize small amounts of anything to the point where it will not show in basic drug tests. Esp if you are skinny no matter how much you eat, male and tall.

The same thing happened to me. THe place were i get the methadone does routine testing, and its in the morning- before i take my daily dose. The methadone is metabolized out of my system in less than 24 hours. In addition to my tests coming up negative for methadone i would wake up every morning in withdrawal. Not too severe, just mild to moderate body aches, watery eyes and yawning. There were a couple days that it was more severe and i had chills and other withdrawal symptoms. They increased my dose slightly because of this and it didn't help. Then i got a larger increase and after 4 days on that dose the morning withdrawals stopped.

They acted like i had been cheating on my drug tests, even made me pee while supervised. I would assume that now that my dose is stable that it will show up in my tests but i have to wait and see. I know that i took the med and it was my pee they tested so it had to be that the dose was too low and it was getting metabolized in a shorter time than most people.

Regarding a recent post by me about a test coming back negative for my Rx'd Methadone, I got a copy of that test. Guess what? It could NOT have been my urine. It came back with none of what I take in it, and other things showed positive that I have never even been prescribed. Urine drug screens suck! Chain of command is bulls***!

If I'm correct because Methadone is completly synthetic ( man made) it doesn't metabolize into morphine, heroin,codeine etc.. again as stated by another response your Dr. should know this. If she looks it up in a PDR she'll probably realize this. Most drug tests check for metabolites that are broken down in the liver and /or kidneys. This usually only occurs with drugs derived from plants. A test for Methadone or any other synthetics can be done via gas chromatograph if the drug is being screened for specifically but is obviously cost prohibitive, Good Luck!!

If you have only taken 5mg b.i.d. for 4 days, then perhaps the methadone hasn't been in your system long enough. However, if you were given a gas chromatography, as she should have, I would have thought it would show up. However, even if it were in your system, if you fall below a cut-off mark, (I believe), then you would show as "negative" for methadone. Hope that helps. Demand the best test available if you are having problems with it showing up. Remember, it is not uncommon for tests to get mixed up, i.e. human error. Demand your rights!

some people detoxify faster than others, it depends on the amount of fluid intake, amount of work or exercise, some medications even have been ineffective, if DR. raises the issue again ask that he perform a observation test where he or his nurse actually watch you consume it an draw blood or urine, after a set time normally 4 hours after consumtion

If you are in cronic pain your body may be using up the methadone you may have to go up a little on your dose for awhile till you build up your system

I found out exactly why there was no methadone in my system. They got my drug urine test mixed up with someone else. The test showed I was ONLY on lorazepam, and I don't even know what that is. Nothing else showed up. At my next doctor's visit, they had a brand new drug screen testing company, and had fired the old one. PROOF POSITIVE: Many people are unnecessarily deprived of their meds because of simple human error. Thanks for all your help!

I have been taking 40 mg q.i.d. of Methadone for 3 years, with other dosages of Methadone over 2 more years, for a total of about 5 years. I recently tested negative for any signs of Methadone in my system. I take many herbal supplements, plus prilosec, estrogen, PseudoFed, Zyrtec, Naprosyn, etc. I take my pills like a person with OCD. I may lose my pain meds now because they think I am selling them, but I have a very severe congenital back problem with lots of pain. I also drink over 8 glasses of water a day, 4-6 big mugs of coffee, and occasionally the amount of a family tea bag in a day's time (24 hrs). I am always thirsty. I also take 3 Tbs of coconut oil p.o. per day for energy and metabolism.

Im terminally ill and on 200mgs of methadone a day and the last 2 months my urinalys has been neg of methadone. Now come on, of course he tests for methadone because thats what Im on. The 1st month he was OK. Last night he was looking at me like a drug dealer, and here in Fl it is neary impossible to get narcotics no matter what your diagnosis is. He is sending it to a lab to verify, but this has never happened. I had kidney tests yesterday, I am wondering if my kidneys are starting to failm if that would interfere with a drug test? He said No No and No to all 3 of my questions, and like the person above, he is the only pain Dr with in 200 miles of me. Im wondering if Im getting old or really cheap generic meds because lately I have had to take more at night, I don't even feel like I took any pain meds at all, and Im on 10 10mgs am 10 10mgs pm? This is very odd, but because all of the drug abuse Im the one that will probably get in trouble. Very strange. I too started drinking coconut milk and oil recently...Maybe it covers it Hmmm

As long as you have a dr's permission to take methadone,or recieve it from a clinic you will be fine.Methadone is not only used for heroine addicts anymore,and is a cheap alternative to oxycontin,because they both have long lasting affects.Just disclose the use to the tester and why you use it.They can distinguish between methadone and oxycodone,and the idea that 5mg.s,4 times a day would not show up after 4 days is ludicrous.Something must be wrong with the test.

The standard 5 panel UDS doesn't test for methadone because it isn't technically the same opiate like the others. There are other tests that will test for it specifically though.

As to the CVS worker, you shouldn't be taking drugs anyway. ...I guess that's why some people get the wrong prescriptions (their employees are cracked out).

I was using the clinic and lying because I'm terminally ill. He cost me 1/3 of my SSI check. He hasn't kicked Mr out because he knows I'll be on hospice soon. But central Fla is busting Drs for lortabs. So us sick Ppl get the run around for meds. He was investigated. Wasn't shut down and I'm locked in CVS. Now they're saying they are choosing not to fill my meds I'm getting an attorney somewhere I feel strongly my rights have been taken away. I'm dying but somehow there's allot of pills on the street. Thx for the info......peace
