Why is no one actually answering the question and going way off topic? I'd like to know the answer to this question too.

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 just started suboxone but I do want to chew a fentanyl 100mcg patch. I get tested every week. How long does it take do get out of my urine? I do dabble with them occationally but I want to make sure its out of my system before I get tested. And please no comments saying "you need a script for it". I just need an answer to my question, not one saying stay awaybfrom it. Can anyone help me out? Ive heard 2 days but then I have people telling me it could take weeks. Which is the right answer?

Been on 100 mcg patch for several yrs..no trouble except patch is only effective for 48 hrs, not 72. Have no side effects. Starting to notice I'm not getting as much relief. tried two patches and was fine and got needed relief.

WRONG. Fentanyl stays in your system for at LEAST a week. My Dr tested me after I had taken it OFF a week before, it still showed up. If you need to pass a test take it off at LEAST a week before, if not sooner. These people that INSIST it's out of your system in two days MAX could be setting you up for a bad test. Don't take some anonymous writer's word for it. Tests are getting more detailed, and can check for everything, longer. If you want to be safe, DEAL with your pain, your addiction, whatever it is your dealing WITH and take only what you're prescribed. It's better to have a little bit every day than to have nothing until your next visit. I'm not prescribed near enough, for my pain and I often run out. Try KRATOM. Sold at head shops and many gas stations. You're not going to get the HIGH you want if that's your goal but you're not going to deal with withdrawls.

If you have a valid prescription, then it does not matter, you simply need to make them aware of it when you have the test.

Fentanyl has a short half-life of only 7 hours, so it will be out of your system in approximately 48 hours.

Levaquin may be the reason that I am fatigued, in pain, and having bowel and bladder incontinence. OR it could have triggered the first horrid episode in which I cringed with every move I made. I have 9 white matter lesions, confusion, and no diagnosis . Anyone else out there living with similar hell?

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...

I've been on 50mcg Fentenayl patch for 3 years, I cut & chew up three quarters of it and stick the last quarter on for 2 days. Last time I was at my doc's I had a urine test and was NEG for anything & everything! How the hell is that possible?!

Huge difference is you smoke it. It stays in your body the longest if you use it as intended which is as a patch you wear. The majority of the fentanyl goes into your blood stream. The half life of fentanyl thru nasal or mucus is only like 6 minutes to 20 minutes where transdermal is 20-27 hours. Also every persons body takes different amounts of time to metabolize the drug. So depending on how you use it it could be hours or days. Hope that helps. Also I agree people don't need to preach on here. People with scripts and without come here for info. You can have a script but use waaaaay too much of it and be afraid of failing for too much of it in your system. I'm not sure if that's possible, but I'm sure if your getting tested you will worry.

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.

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.

Hi, I take Fentora 100 mcg buccaly for break through pain relief only. I had that since it is quick acting, it would not be in very long. Yesterday, after my appointment, the receptionist informed me that I was no longer able to return to the office because Fentora hadn't been seen in the urinalysis for several screenings. Although I explained it was an as neededed med she said it didn't matter. I explained to her that because I drive a very far distance I don't take it even if I need it b/c it makes me sleepy. Today I told the lab tech the last one I took was 3 days ago. It didn't show up. The receptionist said that IF I HAD taken it it would still be in my system...she didn't seem to grasp the concept I don't need to take it sometimes and because I drive a long distance to get to the doctor I do not take it even I do need it, because it makes me sleepy. I feel like my only defense would be to find out why it didn't show up or how long if stays in our system. However, it seems like some say 3 days and others as long as 7 days. I am guessung that the higher the dose the longer it's there.
