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.

my friend chews patches that she cuts them into 4's. she has used a 5 100 mcg, 75 mcg, and 50 mcg patches as i said she cuts them into 4 pieces. She has injected some of those patches that were also cut into quarters. She used them on and off for 1 month. Some days she just did 1 quarter a day. SHe has thankfully quit completely and took all she had and cut them up and flushed them. Thank God! She was also using her dilaudids that she is prescribed. Well now that she quit she has 19 days and has to pass her pain doctor urine screen. This past month is the only time she has used fentanyl and some of those days she wouldnt even use a whole quarter of one. She never wore the patches at all just chewed them a injected just a few times. She is a small person like 5'4 and 117pounds. Shes always been in good health and definitely has a high metabolism. She is 46 and is going through menopause and she sweats constantly especially at night she has to ghet up and change her tshirt she sleeps in sometimes 2 times a night she has to change. Now that she has stopped completely do you think she will be clean for her urine screen in 19 days? I have told her how stupid it was and I was glad to find out the person she got the, from went to jail was just sentenced and got 6 years on probation violation. So glad he is gone!!!! She is stresses oout Ive told her im sure 19 days she will be fine but what are you all's thoughts. Most of the days she only injestingless than 20 mcg. PLEASE PLEASE someone respond so I can show her what is being said by other people other than me. Someone her size with no fat on her and all the constant sweating she does Im sure she will be clean in 19 days. Asd many people as possible rewspond because she is driving me insane and obsessing about it. This has scared her so bad I know she would never put herself in that situation again even if someone other than the guy that went to jail offered her some. Please someone give good sound advice so I can calm her down, Im scared because she has bad panic attacks sometimes and shes had so many over the last few days its ridiculous. I have told her how extremely stupid it was for her to do this and now has to sit and worry herself sick over this. I dont want to be to demeaning to her but I had to tell her that it was one of the single most stupid things she has ever done. Please nobody be mean with your responses she is in a fragile state and she definitely know how dumb it was. I let her know it could have killed her and not to mention jail time if she was caught with those things. i knew something was wrong with her and then she had nobody to talk to. Im thankful she told me and im taking her to her first NA meeting this thursday. She has scoliosis and she is on dilaudid 4mg but she said her tolerance to her medication is causing her not to get the relief she needs. shes scared to tell her doctor that the dilaudids arent working like they use to because she may label her a pill seeker all though her scoliosis is pretty severe. So with that all being said please give some good solid responses so I can ease her mind. I think she will be fine in 19 days so please help me out here. She is my roomate and driving me up the wall! Thank u in advance for taking the time to help me with this.

You are doing the right thing, fentanyl has such awful side effects. Because of the patches my kidneys started to fail, I could only pass a small amount of urine & was in pain. I was lucky as my cleaner works in a nursing home & knew what was happening, I thought it was bad cystitis. I am clear now & will be really careful what I put in my body in future.

I have been reading articles and personal posts for about six hours, regarding the question how long will fentanyl show up on a urine test. It's almost funny. I've read anywhere between two hours to two months. Why is there so much mystery behind the drug fentanyl? Why aren't the straight facts readily available? I need to know how long 2400 mcg, taken in one day by oral spray, would be detected in a urine test. And now I know.....anywhere between two hours and two months! Lol

I've found that doctors know very little about the real facts of pain meds, withdrawals, which drugs are worse withdrawals etc etc.

I gave up fentanyl a month ago, I asked my doctor how long it stays in the system, she replied several weeks. Only now am I realising the nasty side effects, cosmetic things like nails splitting, bad things like kidneys packing up. Short temper & being away with the fairies.

Same type of problem happened to me, except with methadone. I was taking 120mg a day for five years. My
fault because a dentist gave me a script for 8 Tylenol 3's. Good lord, so I could not get a refill at all. I begged and pleaded for days just to get a refill so I could wean myself off gradually. They just did not care. Any time I ask a Dr. For pain-control these days, I am automatically tagged as a drug seeker. I have spine diseases, fribro and scoliosis. I am always in horrible pain. I am about ready to toss a brick thru a pharmacy window so maybe I could get a referral to a methadone clinic.

I stopped using fentanyl patches 2 weeks ago after using them for 4/5 years. I stopped as I was fed up with sweating, found they were not stopping my pain & other side effects were beginning to appear. I have had quite a bad withdrawal, seems okay now - apart from burning urine, which I assume is the last problem. May I say that if people can run a mile or two to ease the withdrawal, why were they using fentanyl? I used the patches for severe spinal pain, I can hardly walk a quarter of a mile. I stopped the patches 'cold turkey. ' as I am between doctors & did not want more
chemicals. Good luck to you all, just remember you have only one body, abuse it if you must, your choice.
