Fentanyl urine test

Common Questions and Answers about Fentanyl urine test


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. There is nothing wrong with using surgical tape or any kind of bandage to keep the patch in place. It does not affect absorbtion rates. Even so, some people never can find a way to keep a patch in place or end up allergic to the adhesive and have to discontinue its use.
Feeling weird weird on these and thinking it's just the start up feelings from the Fentanyl. I'm also on on Celexa and that apparently is not a good combo. So i asked the Doc to get off the Fentanyl and he said OK and gave me my normal dose of Vicoprofen. Of course i'm having big time whidrawls from not being on the Fentanyl. So my question is what do i need to overlap 75mcg off fentanyl?. do i need to go to Percocet or something else to not have the whidrawls coming back ?.
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. I'm so relieved to finally have a constant relief to the worst of the pain that I do NOT want to risk loosing this relief.
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.
Perhaps there is a problem with absorption from the patch? Your doctor may have access to a urine test that can show if you're putting out fentanyl metabolites. This will check whether or not you're absorbing the medicine. I used to break out from the patch, and after the two or three days, would apply triamcinalone cream or some other topical steroid to the site. Usually the irritation would heal in 2-3 days and the site would again become available. You need to rotate the sites.
I realise now that the urine retention problem I had was also caused by fentanyl. I am between doctors, I had no confidence in my last one & haven't seen my new one yet, I have an appointment on Monday. I will make sure that I research any drug they want me to take. I am feeling human again. Good luck to all trying to stop, it is worth while.
I recently took a urine test for the doctor and she said that a drug came up that I have never even heard of. I think it starts with an O. But, when she checked the pharmacies to see if I got a prescription for it it never showed up. BECAUSE I NEVER TOOK IT! But, she did notice that I accepted a prescription of Darveset that I received. Yes, I was wrong for accepting it. I was passing a kidney stone and the pain was too much to handle. It ended up being a 6 mm stone.
This is what he may have to do before every urine test, unfortunately. I wish I could tell you how to find those articles. Maybe you can look for the names of the people that posted them? I really hope everything works out for your husband. Oh, I almost forgot to ask. Was your husband past the time when it was time to change his patch? Maybe that effected the test. I'm really not sure how long the medicine from Fentanyl patches stays in your system.
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...but was just wondering how long it would take to go thru one's system...
Similiarly - some poor soul who does not take your meds probably is as floored as you are with their results. Also I would DEMAND a blood test not a simple urine test. You can also file a complaint with the medical board in your state and the AMA stating your case. I know how hard it is to find another doc to pic up prescribing the meds you are on and I wish you much luck and many prayers.
I'm sorry for the people that can't re-take the test, I think they should allow you to take the test again, let you put on a patch and then later do a urine test in front of them and see if the fentanyl shows up at that time. Instead these doctors that are testing patients and that are coming back with no fentanyl in their systems are just removing them from the practice and it just seems so cold.
What comes back from the doctor after a urine test at a primary doctor on pain contract?
I don't think it has been a year yet, I have been on 50mg fentanyl patch. You guys are scaring the hell out of me. I am 55 and have suffered with back pain for a number of years. I also have fibromyalga. My son is 22 and gas has been a user and abuser of Oxcotin 30mg soma and valium to what extent who knows. For years first becaususe of friends and then because he has a 3 hurniated disks bad, and this has just come to light.
I'm wondering if anything could have effected this urine test. The fact he refused to retest with blood test bothers me. I take my relationship with my physicians very seriously & I know how difficult it can be to find great PM physicians. But without trust & mutual respect there isn't the right relationship. Anyone have thoughts on how this test came back like this? I've worked in the courthouse & we use urine tests because they're cheap.
last week i had to take a urine test for a new job. i take 140 mg of oxycontin and 45 of roxycodone a day. i thought they would bring up a positive for opiates as i had a half days worth in me to begin with. but no my test came up clean. the only thing i can figure is i'm on a diuretics for high blood pressure. i knew it really kept me flushed out, but i didn't know it worked that well!!
Different doctors and clinics and I convinced them that I just moved and no longer wanted to be on the patches no more, so instead of taking the drink they prescribed me a meth pill, I was at 80mg a day and always made sure that my pee would be clean if I had to due a urine test. This way I was abusing my patches in two weeks or less and then just used the pill for the remainder till I got my new script.
i am on the fentanyl 50 patch for ongoing hardware problems after a L4-S5 laminectomy with fusion in nov 2008. i also take Lortabs for occasional breaththrough pain. my doctor occasionally "drug tests" me but i am always too embarrassed to ask exactly what they test for. i dont do any illicit drugs and do not take any drugs not prescribed to me. my anxiety at this time is that i also have Klonopin prescribed to me by the same MD but only rarely take it.
I am prescribed fentanyl patch for failed back surgery syndrome. The doctor gives a urine and lab test to make sure I am taking the meds because the DEA? or whoever it is is cracking down on him. the problem is it doesn't show on my test. he says it could be because of protein in urine. does anyone know if this could be true? Other meds I take do show up.
i have an appointment in 48 hours for an after care program and they are going to do a urine test to see if i have been using. My question is how long will the oxy's stay in my urine? if i don't touch another one will it completey be out of my system? Someone please respond.
When asked if I took any meds I told them I took a half of a pill the day before . I wasn't suprised when my urine test came back negative that first time. I WAS FLOORED when I was summonsed to an earlier-than -scheduled appointment this afternoon and summarily told by a PA that my last urine test taken week ago at 8am came back negative too. I took my normal dose @8PM THE NIGHT BEFORE!
•A popular and effective way to beat the test is by substituting “untainted” urine for one’s own by carrying a concealed specimen into the bathroom. The only way to thwart this is by supervised urine collection (ie, a staff member observing urine leave the patient’s body and fill the cup). While this is required for forensic urine testing, it could be the ruin of a typical medical practice; it is upsetting for patients and demoralizing for staff.
i have not used drugs in the past thirty days, but this past friday i took a 10mg lortab. today is monday and i have to take a drug test. do you think the lortab will show up today?
That way it will all be documented shoudl they decide to give you a urine test on that day - chances are, if they did, it would show that too much med is in your system, but that would be because of the ineraction between teh patch and the antibiotic. I know my post seems a bit involved and strange, but in basic words - using erythromycin - or an antibiotic in that same family - can greatly increase the amount of fentanyl found in your blood plasma.
I went to pain management today and failed the urine test. I will have to wait 45 days to be retested before they will prescribe anything for me. Meanwhile, I do not have any more patches and I am about to be put in Fentanyl hell if what I have been reading on this site is any indication.
Well by this time I had ONE patch left to use only! I started crying, he said to sit. A few moments later I am brought in only for a urine test. So now, I am going to facing withdrawl with nothing! I don't even have anything left hanging around. I am so screwed! What do I do? How bad is withdrawl from Fentanyl? I am on the 50's. Do I somehow get to a ER? And hell, tell them that same screwed up story, yet its the whole darned truth? Oh man please help. Thanks so much!
I also take a urine test at every visit. I have been able to take my meds EXACT AS PERSCRIBED for years now. I also turn down the offer by the doctor for more or for the Zanex, Ambien etc because I know how hard it is to get off. If you go to detox and it is not hard then you will end up right back where you are now or worse. For your kids please take my help. Start a post on the addiction board and I will meet you there. this is not the place to post at all.
I have now had three urine tests and one blood test over the past six weeks for a 12mg fentanyl patch. I have used these for over two years for pain related to a breast cancer chemo.x After the first two urine tests, I had to insist on the blood test, but it didn't show up there either. Has anyone ever had a similar false negative???Any ideas?
I was on a 100 micro gram per hour pain patch (it takes 1000 micro grams to equil i milligram) I assume the test used was a Immunoassay test. that is a broud spectrum test for opites.That test has a minimum threshold, that means there has to be a certain level of the drug in your system B 4 it will flag an opite responce.AND!!!!!!!!!!!!!!!! ONLY!!!!!!!!!!!!!!!!!! 6 %!!!!!!!!!!!!!!!!!!! of the fentanyl is excreated in the urine.
Most pain management programs have gotten strict, if the rx that is old was in your name you may be ok but its really up to the doctor, running out of meds in the programs here is just as bad as doing illegal drugs. Technically the Vicodin is a variance, its hard to say how your doctor would feel but mine requires me to take my rx & nothing else and have it in my urine when he asks me to take a test b/c with any variance you could loose your medicine. It all depends on your doctor.
