How Long Does Fentanyl Stay In Your System For A Urine Test (Page 2)
(Newest replies first)

Updated

On Saturday I chewed a half of a 75 mcg fentanyl patch for the first time ever. Will it be in my system on Monday around 11:00 am for a urine test?

Everybody please take note. My last doc just did a dip stick urine test in the office. Current do sends it out to a lab and you find out on your next appointment. Please specify what kind of urine test to get a correct answer.

You all sound like dope heads not someone who needs pain meds for REAL pain relief. U just put all ur laundry out there for people to read like it's a good thing. The one guy who chewed on a patch, r u serious. I would be ashamed to admit that to the public.

Campbell, I'm SO sorry for what you're going through. YES, I know for a fact that pain management clinics and other providers can order drug compliance tests that will show that you test positive for this drug metabolite or that drug metabolite. It shows up that way because the vast majority of pain management providers are completely clueless about WHAT test to conduct to show compliance for that particular drug. Different opiates are metabolized by the liver in certain particular ways, and as the metabolism of the opiate occurs, the metabolites of that opiates you take is then detected in your urine in concentrations that are compatible with the dosage you are prescribed. Where providers make a huge mistake is when ordering a test that isn't compatible with the metabolic pathway (the breakdown of a drug into its specific metabolites) of the prescribed drug. Then the patient's drug test comes back positive for, say, morphine...which perhaps ISN'T the metabolic by-product of their prescribed opiate because their provider didn't order the correct compliance test because of their lack of knowledge concerning the metabolic pathway of their patient's prescribed opiate. But you said you were drug free and fentanyl showed up....wtf?? Excellent that you have legal counsel. Mistakes are made every single day. Many of them. Fight it every step of the way. Good luck to you and God Bless!!

I've been drug free and want to know can a person dope your urine test with that drug called fentanyl? If so when it went to the lab for testing my medication never showed up ..when I was told I tested positive for just fentanyl I went nuts! I asked for the labs name and they wont give it to me! Which is why I'm asking if someone can dope your urine with that drug? Otherwise it's the lab somehow but something isn't right! I am going to mro to see whats up. They are quality control employees of the lab and whom my lawyer now has to get involved... Omg I never believed people I always said yeah right you wasn't positive and now I feel terrible for I'm going through this s***!

Using any kind of drug for recreational reasons, I always said junkies can always tell you the best ones, methods of introduction into the body, etc. However, bottom line is, if you are doing them as prescribed and honestly, you have no worries. I have cancer, and doctors aren't stingy, and want to inflict pain by NOT writing scripts for stubbed toes, they have taken oaths to help. And most people aren't showing up for help. They show up for narcotics. Period.

Addiction must be strong if you're willing to suck on a patch someone other than yourself has worn. So gross. Go to rehab

I buccally ingested a Mallinckrodt Pharmaceuticals brand of a Fentanyl 25 mcg/hr X 72 hrs transdermal system that had already been worn for 72 hours (not on me). I used it for approximately 20 hours..although I'm sure the system had absolutely no Fentanyl left in it or in the surface. I was tested by urinalysis exactly 28 days later. The laboratory utilized by my pain management clinic is Aegis Laboratories..and I'm also confident that the lab uses GC/MS technology when analyzing the urine. Will THAT test come back negative? Oh, I fervently hope so.

Hi...I put a used-72-hours 25 mcg Fentanyl patch in my mouth sublingually for a day and a half until there was just plain plastic in my mouth. Surprisingly, that old patch had a little Fentanyl left on it...I could tell because it tastes bitter. I did not have a urine test until 28 days later. Is there ANY chance any of that Fentanyl (metabolites, etc.) showing up a whole 28 days later? I have been non-compliant on a couple of tests until they increased my dose of Dilaudid. I know they use Aegis Laboratories. I think they also utiluze Gas Chromatograph Mass Spectrometry testing and/or the most sensitive tests currently available. I am SCARED TO DEATH, but sincerely hope I am okay. Please respond. Thank you so much in advance for your consideration and help. :-)

Most pills and powders, i.e cocaine, molly (ecstasy, mda, mdma) stay in your system for 3 to 7 days. They exit the system faster because they are water soluble. Marijuana takes around 30 days cuz it stores in fat cells.

I've been on the 50mcg Fent patch. I had a drug test last month and even after the patch was off for 3 days It still shows up on a siliva test. And yes it says it's Fentanyl NOT morphine like ppl have posted it saying it would. Give yourself two weeks without any patch to be clean on a test. Just wanted to share my experiance since I read so many Wrong posts!! I'm in pain management and I'm given Meds however the patch was given to me by the hospital and the dr questioned me Big time! It's like eatting an orange and saying it will say I had an apple. If you take any Fent it WILL show up in urine and saliva tests!!!!!! I wish someone told me the truth. Hope this helps someone !
