Common Questions and Answers about Fentanyl urine detection

Avatar m tn I drank three smal cups and produced a urine sample that was good. I went back last week and they requested another urine sample. I didn't have to go and was cut off at two cups. After that the Dr and nurse were really pressuring me to give a sample. It had been an hour and the Dr told me I had one last time to try or they were going to take me off the methadone. I tried and did not produce.
Avatar m tn We agreed that with Fentanyl being widely abused, it would be appropriate to get a urine drug screen. Approximately 9 hours after the medication was allegedly administered, I tested negative for opiates. According to the FDA, the half-life of fentanyl is approximately 218 minutes. How many half-lifes would it take before the substance would no longer be detectable in urine? Who would I report this possible issue to? Thanks.
Avatar m tn Hello, I had high risk exposure in thailand with a sex worker, and just got my blood and urine tests back today, (Ireland) all tests were negative, my lymph nodes feel like a dull ache? I know syphilis has a 3 month window, but is it usallly detectable 7 weeks posts exposure?
906738 tn?1251010478 Did anyone at the clinic ever actually look to see that you had on a patch when the test was performed? That should be something in your favor at least. Most pain clinics only perform a general opiate survey unless the doctor suspects a problem. It's pretty expensive to run a test that identifies individual drugs, and if so that's usually a blood test rather than a urine test. I understand that fentanyl is particularly expensive to identify.

Avatar m tn Would ingesting or chewing a piece be enough to have a positive urine test? How quickly does Fentanyl show in the urine? My previous tests have not been a problem because I've had 'accepted level' of Fentanyl....though I don't know what that is. Previously I was on oxcodone for over 7 yrs and when I started abusing, I was switched to the patch and have not abused since.
1381087 tn?1279223327 First off let me say that I've never used Fentanyl ever and haven't had to do a urine test. I do take vicodin for my pain. But what I wanted to say is kind of what you were talking about, I've been reading on the posts lately and it does seem like there are quite a few people that are failing the urine tests with the fentanyl.
Avatar f tn As of the past 5 days I have been nauseous, have heartburn, broke severely in odd places (back, shoulders, neck), have mild cramping, mood swings, flushed face, etc. I went to Dr. and had a test today... neg. of course. They do not have early detection tests and said even if I was pregnant they wouldn't know. Does it sound like I may have had implantation bleeding? Do early detection tests work for most people? Do I sound pregnant? It is silly. I feel like I am.
Avatar f tn They said it is extremely difficult to detect fentanyl in saliva and that these tests are not normally used for fentanyl patch users. They said urine tests are much more reliable and that I should have been given a urine test in their opinion. I also learned that I should have been told to wait at least ten minutes after eating or drinking, before taking the saliva test, because this can cause the results to be wrong.
Avatar n tn I'm on 125msg/h fentanyl patch, whats the recommended time for getting off the patch? my dr. is lowering it 25mcg/h every 20 days after being on the patch for 12 years. ALL BECAUSE MY URINE YESTS CAME BACK POSITIVE THIS YEAR AND THE LAST 4 YEARS TOO. BUT THEY DID NOTHING THE PREVIOUS 4 TEARS.
Avatar f tn How close to a urine drug screen would I take my last 500 mcg. Fentanyl Troche for it to show up in my urine?? I happen to have a REALLY bad month & I want to make sure that it shows up positive...I can also explain to my doctor the horrible month I've have (some new pain & also some SERIOUS mental health issues with my son that I'm sure did nothing but make my already bad near daily migraines all the more worse...
Avatar m tn Fentanyl (Transdermal, Transbuccal, Transmucosal, Sublingual) Norfentanyl 4-N-(N-propionylanilino) piperidine 4-N-(Nhydroxypropionylanilino) piperidine 1-(2-phenethyl)-4-N-(Nhydroxypropionylanilino) piperidine (Source: Remitigate.com) As for my experience with transdermal fentanyl, when I used that patch, I found them effective to 2 days only, after only 3-6 months of use. For me, the problem with transdermal fentanyl was a rapid development of opioid tolerance.
Avatar m tn I now have major surgery coming up in a few weeks and the pre-op tests indicated white blood cells in the urine. A culture has been ordered and pending the results, I will be put on a heavy dose of antibiotics between now and the surgery. I have a history of prostatitis so this is the assumption. Obviously, I need to get my wife tested and treated.
Avatar f tn a week later who said the lesions looked like herpes and the discharge was probably bacterial so he sent me to get tested, both urine and blood. The results came back negative across the board (herpes included). Is there a time frame for detection? It was about 2 weeks from unprotected sex to lab testing.
Avatar m tn So anyways I am going to a methadone clinic because I got addicted to pain pills specifically fentanyl. Tje last time I used was january 6th and I have been 100 percent clean since then. I had a random drug screen that is a urine test that gets sent to a lab so its pretty thorough and I tested positive for fentanyl 3 months after i used last. Is there any explanation for this.
Avatar f tn I made a mistake with my calendar. I'm supposed to change patch every 3 days, but I forgot and didn't replace my patch until later on the 4th. I had my urine test sent in on that 4th day and I just realized what I did! It would be ok but I want to make sure the fentanyl test comes back positive from the lab. I've been a FAITHFUL pain management patient for almost two years and it would crush me if my doctor didn't trust me.
Avatar m tn The detection period in case of saliva drug test is around 20 hours to 1 day approximately, whereas it is around 3 days in case of urine drug test. The accuracy rate of urine drug test results is much higher than that of saliva drug test results. It is a fact that the risk of false negatives is high in both of the these tests. It is also a fact that there are no set of standards in place that require lab validation. One would assume some labs are more accurate than others.
8617041 tn?1409634201 I did.. I found on the first day of my missed period (which was a Thursday)... I went to the Dr on that Monday and they couldn't confirm with urine test. Did a blood test and confirmed it.
Avatar f tn I repeated the next day but not with first urine and with a different non early detection type test and they were negative. Well today Sunday I repeated again with early detection and once again got faint positive lines on both tests. I have not really had anymore cramping or spotting just bloated and look about 3-4 months pregnant. How could this be possible after a tubal in 2009??????? Has anyone else had this experience?
Avatar f tn Because oxymorphone has a longer half life than oxycodone, it is often present in the urine after oxycodone falls below the detection threshold. See PPM for more info: http://www.practicalpainmanagement.
356518 tn?1322263642 A.Preliminary Screening of patient-provided specimens, usually urine, at the point-of-care (POC) to detect the presence or absence of a limited number of prescribed and non-prescribed drugs of interest. The accuracy and reliability of relatively inexpensive POC screening assays are limited; although, more costly laboratory-performed assays can be of higher quality. B.
