It stays in your system longer than 2 days my friend. I am on the patches myself and my purse was stolen on a Friday evening, I went to the Dr that following Tuesday to get all my scripts refilled and its mandatory at my Drs office for them to give you a drug screen in an instance such as this, my drug screen still showed the fentanyl and the flexeril.

Many people chew them, you seen ti be very well read however not well experienced. I mean no offence. Just that what the text books say are not always the facts.

check this out: Drug Use Time Table - but I've read several comments stating that their urine test failed even after a couple weeks... so who knows.. I'm pretty sure that the longer the person has been taking it, the longer it would take to get out of their body...

Take 12 days 14 to be safe and no way that u can pee clean any sooner unless you try to flush ur system that's could help a bit. I know this cause I'm apart of a methadone clinic and the nurses straight up told me. And they would know they test pee all day long.

I hate to say this, but I stopped two weeks before a drop at a pain clinic and was very positive. Got dropped from my pain meds (three five mg norco a day) I am screwed because I need to have around the clock pain control. I'm scared because I can't go a month without something for pain, I would go nuts! I can get norcos, oxycontin,fentynal,vicodin,xanax,Valium and dilaud. I can't get any of them continually, so I have to switch around the types! I just want to have some relief. I cannot play their game anymore. Good luck on your drop, I will say a prayer for you.

I appreciate your passion regarding judgmental people. We all have vices in life while some might be legal in your geographical location or not or more socially acceptable in your region or less accepted, we all have them.
Thank you for speaking out against the condemnation that is typically rooted and stems from hypocrisy.
I would like to amend your statement about how long Fentanyl stays in your system. This is what I read on a website showing research regarding the half-life of fentanyl. *For those whom are not familiar with what a half-life is, it is the amount of time required for an average person to metabolize and excrete 1/2 the amount of a substance in your body. Every substance has its own biological half-life and is excreted in its own way (x% in urine, x% fecal, ect.). After 5 half-lives a substance is considered excreted from the body. However, if you continually consume a substance before the original amount taken has been excreted the amount present will add to the additional amount taken and it might take additional time to be completely excreted.

For Fentanyl (this is from the Mayo Clinic):
The mean elimination half-life is (1-3):
-IV: 2 to 4 hours
-Iontophoretic transdermal system (Ionsys) terminal half-life: 16 hours
-Transdermal patch: 17 hours (13-22 hours, half-life is influenced by absorption rate)
-Transmucosal:
- Lozenge: 7 hours
- Buccal tablet
- 100 to 200 mcg: 3 to 4 hours
- 400 to 800 mcg: 11 to 12 hours

All this being said, this does not tell how long it takes to excrete the metabolites of fentanyl (which are normally what are tested for with all UA tests of any substance) to be excreted and if you are continual taking high doses before the previous amount has been excreted then after 5 half-lives there might still be a detectable level of the metabolites in your system.

On a side note, people, please give a proper description of the amount you have taken if you want people to respond. I read someone who said they chewed 100mg of Fentanyl. If you did that you would be dead. Fentanyl is approximately 80-85% stronger than Morphine so it is administered in mcg NOT mg! That is 1,000x the difference.

Good for you that fentanyl is some bad s*** great for pain though I don't believe Dr's release the fact everyone system is different when they prescribe fentanyl they should make contract with the patient that when fentanyl is stopped it should be done in a slow process not cold turkey I know we ex users all went threw hell if you 've been forced to do it cold turkey it's been almost 4 months for me and I still get have with draw it keeps getting triggered back some how

I am in UK, not sure if it makes any difference, my doctor told me that it takes weeks for fentanyl to leave the system. My kidneys clung on to the last vestige for 5 weeks, I am clear now. I stopped using patches, 75mgm on 29th May.

I'm kinda in the same situation. I used fentanyl one day but it was a lot. A week later I had my pain doc appt, which was last week and they took a urine sample. They hadn't done a test in 3 months so I think I was overconfident and did the fentanyl. STUPID. I'm really scared it's going to show up and I'll be getting a letter in the mail dismissing me from their practice. I've had 3 back surgeries and I have severe chronic pain. I've been on pain meds for 20 years. If I'm dropped my life will pretty much be over. About your friend, it depends on if they send her sample to a lab. A lab will probably find it. I've been told that the tests they use in doctor offices usually don't detect fentanyl, BUT others say they do detect it. There's a lot of diversion on the internet regarding fentanyl and drug testing. Unfortunately she's just gonna have to cross her fingers and wait cuz there's no definite info on fentanyl drug testing. Good luck.

The sweating old be caused by fentanyl, it is one of the many reasons I stopped using them. It took me 3/4 weeks before my urine was normal.
