Fentanyl urine drug screen

Common Questions and Answers about Fentanyl urine drug screen


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 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 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 f tn I have passed every test for 3 years on my bi-monthly urine screen. All of a sudden I am showing positive for oxycontin and I have NEVER taken this med. Now I know that actiq,opana,stadol,and oxycontin are synthentic oipioids. Now I have taken a blood test for oxycontin only to make sure this is negative and a true false positive because I do not take this pain med. I am so upset because I have had to go through withdrawls and they are worse than the pain.
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.
906738 tn?1251010478 not supposed to b urine drug screen for patches, monitor plasma levels, ever had amalydosis? It increases amalyse and gov states plasma test, if pain doc trust enough to rx patch, not doing cont. ed. if he or she fails to do this test you might be in for a big surprise.
Avatar n tn I was on a 75mic patch last year, every 48 hrs, and the pain doc informed me that Fentanyl would not show up on the typical drug screen. I was lucky enough to have never been randomly selected and I am subject to random drug tests. According to him Fentanyl can be found but the test is quite expensive so most screening stations just dont do it. If the drug screen you are going to take is job related I would not chance it.
Avatar f tn I tried fentanyl patch but was very scared of the strength so stopped and wont go back there. How does talwin show on a urine drug test and how effective is it really. Also on tramadol er with my norco.
Avatar f tn What sort of drug screen is it? Urine? Blood? I havent smoked marijuana in a while but im still curious as to whether or not I need to be worried.
5330576 tn?1366526999 Hi, {This was originally a response to another post, concerning false positive urine tests and accusations associated with such.} Information below in my post CONCERNS ME GREATLY, as a Pain Management patient. I would love ANY thoughts or ideas. I'm ALSO INTERSTED in knowing of PM Medications that are having a higher incidence of NOT showing up in your TYPICAL Pain Management urine screen... I know the NEW OPANA is one, because I'VE HAD A FEW FALSE NEGATIVE URINE TESTS!!
14468396 tn?1434674089 10 years ago I had the Roux-en Y Gastric Bypass surgery, which gave me malabsorption syndrome. That means that food, vitamins, minerals, meds, ect...do NOT digest in my "pouch", they digest in the lower intestine or go through my liver. So all meds had to be adjusted. I have had the same doctor for 3 years, she put me on Fentanyl 25 every 72 hours and 4 norco 5/325 for break through pain.
Avatar f tn My PM doctor was prescribing 50 mcg fentanyl patches to be applied every three days. They were going to give me a urine screen, but I have interstitial cystitis and a neurogenic bladder. I was unable to provide enough urine, so the nurse gave me water to drink. I was on my way back to the bathroom, when someone other than the nurse stopped me to say I was having a saliva test. I went back to the room and continued to drink water, because I have dry mouth from taking Lyrica and Lamotrigine.
Avatar f tn To provide a concrete evidence for this you can have a urine drug screen done. In regular users this screen should remain positive for two days. Also please ask your doctor or enquire at the lab, if they are using a oxycodone specific product for screening, as the more common opioid screening for morphiods does not detect oxycodone presence. Emphasize for the specific test. Hope this helped and do keep us posted.
Avatar f tn Can anyone tell me if Tramadol will sow up in a Health Care Professionals urine drug screen? And if so, how long will it take for it not to? In other words, how long does Tramadol stay in your system?
1379106 tn?1279033147 re probably only doing a general screen. You can easily test negative if you drink a lot water and the urine is very diluted. That counts as a "flush" in drug testing terms and is usually an automatic fail. You'll need to try to find intelligent life at the lab to explain to you exactly what they've been told to look for. They might also be able to shed more light on why false negatives can crop up than the doctor can. Another possibility is lab errors.
Avatar f tn My pcp doctor drug tested me and claims NO drugs were in my system ! She claims i broke the drug contract i signed and wont see me anymore. How is this possible ? I demanded a retest and was told no, the dr even suggested my caregiver was taking them or we were selling the stuff ! Im going thru withdraw now, alone with no weening just an abrupt stop cuz she wont refill the script and dont know where 2 turn.
Avatar f tn m sorry for what you have and are going through physically - and now the mental anguish of a failed UDS (Urinary Drug Screen). I hear your story so often here - and I hold my breath every time I have to take a UDS for fear my results will be misread - or a human error will occur. Most of us live in fear. UDS have become much more accurate in years past - the one factor science cannot control - the human factor, human errors.
Avatar f tn I was given a urine drug screen last night that tested positive for benzos. I have not been on any tranquilizers! My current medication regime includes Effexor XR 150mg bid, Seroquel 200mg, taking 400mg qhs, Betaseron 1cc qod subq. I was put on Bactrim last week bid for 5 days for a urinary tract infection. In May, June and part of July I was taking Trazdone 200mg qhs, but then switched back to Seroquel 200mg, taking 400mg qhs. I am confused as to what caused the positive test for benzos?
Avatar f tn Dehydration will not effect a drug screen either. It is not rare for a urine drug screen to be in error. Unfortunately like so many other ppl that have erroneous drug screen there really is no recourse for you. I wish I had better answers for you. Talk to the HR Department or your boss. Ask for more information. I too am curious as to what was found in your urine. Good luck to you.
221387 tn?1210933058 If your asking if you can fail a drug test by taking over the counter unisom the answer is no. I used to work in a clinic where we did random and pre-employment drugscreens for many area companies including the hospital where we were located. A drug screen tests for marijuana,cocaine,PCP,benzodiazipene and meth.
