I stopped the patches/percs ct to get a baseline on how long I could go without meds; patch has a half <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>life</<span style = 'background-color: #dae8f4'>span</span>> so I had to wait almost 24 hours for full wds. 3. When I couldn't take the wds, I took a half (2.5 perc) a pill 4. For the 1st few days, I needed a 1/2 perc every 50 mins; set my watch alarm to remind me to dose but I knew 5. Gradually lengthened the time until I was about 6 hours apart with 1/2 pill and then quit 6. Used Tyl and Tyl PM to get me through the rest of the wds. 7.
I began taking it even when I did not need it for pain and became addicted and tolerant to the medication... About 5 months ago, I got on <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>fentanyl</<span style = 'background-color: #dae8f4'>span</span>> Patches at 25mcg then increased it to 50, and now am on 75... I need to get off this and tried last month and I couldn't, it was too hard... My question is, what is the right way to get off of the <span style = 'background-color: #dae8f4'>fentanylspan> without wanting to die. I am a registered nurse and am getting my nurse practitioner degree and will be done with my masters degree shortly...
Fentynl is a very difficult drug to withdraw from because the half <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>life</<span style = 'background-color: #dae8f4'>span</span>> of the med is 2-3 days. Since you haven't been on them to long, you should be OK...maybe minor wd issues. Read the Thomas Recipe, Aminos, etc. I stopped using the patch by using my break through meds, percs, to taper.
Went to the pain clinic and he put me on the <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>fentanyl</<span style = 'background-color: #dae8f4'>span</span>> patch 12mcg. I have so many drug allergies that the drs are limited as what they can give me. I am ok with one patch but when I put on the second patch I got chest pains, nervous, nauseated. Took second patch off felt better. Call dr next day told them what happened. He said to take up to 3 10/325 hydrocodone a day. Took one and it overdosed me. took that patch off too.
My last appointment I saw someone new, a PA who decided that he doesn't like <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>fentanyl</<span style = 'background-color: #dae8f4'>span</span>> because it is too addictive. His plan is to get me off the patch. He cut my dose in half to 25mcg every 48 hrs. and prescribed 5 norcos a day to help with the withdrawls. I cannot take that many norco a day and function. I am crying more, have had a panic attack and my pain is by no means under control. I feel helpless and hopeless. I suffer from chronic back and leg pain. It will never get better.
Feeling weird weird on these and thinking it's just the start up feelings from the <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>fentanyl</<span style = 'background-color: #dae8f4'>span</span>>. I'm also on on Celexa and that apparently is not a good combo. So i asked the Doc to get off the <span style = 'background-color: #dae8f4'>fentanylspan> 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 <span style = 'background-color: #dae8f4'>fentanylspan>. So my question is what do i need to overlap 75mcg off <span style = 'background-color: #dae8f4'>fentanylspan>?. do i need to go to Percocet or something else to not have the whidrawls coming back ?.
I hope not because the half <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>life</<span style = 'background-color: #dae8f4'>span</span>> of the patch is days and the injectible is 186 min i think. I am hoping the withdrawal from the injection will be much shorter than from the patch. please let me know if anyone has any onput on this or how the half-<span style = 'background-color: #dae8f4'>lifespan> of a drug relates to the withdrawal one can expect when comming off the drug?
According to the FDA, the half-<<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>life</<span style = 'background-color: #dae8f4'>span</span>> of <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>fentanyl</<span style = 'background-color: #dae8f4'>span</span>> is approximately 218 minutes. How many half-<span style = 'background-color: #dae8f4'>lifespan>s would it take before the substance would no longer be detectable in urine? Who would I report this possible issue to? Thanks.
I don't know specicially about withdrawal from <span style = 'background-color: #dae8f4'>fentanylspan>, but I do know that it is a very strong opiate. Most full opiates have a fairly short half <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>life</<span style = 'background-color: #dae8f4'>span</span>>, if you have already been through 3 whole days of withdrawal, then you are well on your way. You shold start feeling better tomorrow or the next day. Typically the worst symptoms are over by day 5.
I don't want to spend the time I have left wondering how to get more drugs. I want to experience my <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>life</<span style = 'background-color: #dae8f4'>span</span>>. I desperately need help and support though, because I can't seem to control my urge to use.
I have been in <span style = 'background-color: #dae8f4'>fentanylspan> 75mcg/ every 48 hour for 2 years just stopped two weeks ago, people don't realize how potent <span style = 'background-color: #dae8f4'>fentanylspan> is I'm actually shocked a dr put you on that after surgery it's only want for people who need around the clock high amounts of narcotics and is given when things like oral morphine don't work, to be perscribed 50 of dent you are aupposes to be tolerant to aroun 200-400 mg or oral morphine I used methadone to get off of the <span style = 'background-color: #dae8f4'>fentanylspan> and I was on oxy before that methadone i
i have recently started using <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>fentanyl</<span style = 'background-color: #dae8f4'>span</span>> patches for chronic pain i have had for over 2 and a half years. when looking on this website and others i have found lots of articles suggest these patches could be dangerous and have many side effects and long term problems. i just wanted to ask whether others have found them safe to use?
The last 5 days(I hope my math is right) I was cutting the Darvocet in half and really sticking to taking a half of one every 6 to 7 hrs as needed.. I feel really pretty good. I have not had a Darvocet in 2 days. I have insomnia & intense malaise. Maybe a little axiety in my stomach. I have a few Valium (no history of Benzo abuse) & take only one at night but it only helps me sleep maybe 2 or 3 hrs. Do you think the <span style = 'background-color: #dae8f4'>fentanylspan> is out of my system by day 8??
For the past year I have been taking 75 mcg <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>fentanyl</<span style = 'background-color: #dae8f4'>span</span>> patches every three days.I need and want to stop and get back to living a clean FUN <span style = 'background-color: #dae8f4'>lifespan>.I don't get them by prescription so I can not goto a dr to taper off.I have tried on my own and it was total HELL! The thought of those feelings again scares me to death.I read about Suboxone and wonder if someone here can tell me how it worked for them.Also money wise how much did it run?
Hello Everyone! I could really use some help PLEASE!!! I was on the <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>fentanyl</<span style = 'background-color: #dae8f4'>span</span>> patch for about a year and a half, started out at 25mg then went up to and stayed at 100mg...I am on day 4 of NO MORE PATCH...I am going absolutely mental, I could use any advice and help you can give me...I have the shakes, chills, no energy, no appetite, on edge so bad, and don't want to do anything but sit in front of the tv all day. I have a husband who is so wonderful, but he doesn't understand.
When discharged the end of April I was given scrips for <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>fentanyl</<span style = 'background-color: #dae8f4'>span</span>> 50 and liquid morphine(I had a feeding tube nothing by mouth) the morphine was comparable to quitting Tylenol no problems at all. I am trying to get off the <span style = 'background-color: #dae8f4'>fentanylspan> so I can finally get back to work now that I am feeling well. Or I thought I was feeling well :,( this is the worst medication EVER!
I have been told that when they are prescribed in older people, doctors intend for them to stay on <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>fentanyl</<span style = 'background-color: #dae8f4'>span</span>> for <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>life</<span style = 'background-color: #dae8f4'>span</span>> which is probably why they don't discuss with people such as your husband about withdrawls and how to come of them safely. All i was told was that if i came off them my pain would return. I think this is an understatement compared to the problems people on this website have suffered with withdrawl.
The <span style = 'background-color: #dae8f4'>fentanylspan> patch is 80 TIMES STRONGER THEN MORPHINE ! If you aren't liking the way you feel on the MS Contins, which are essentially morphine, then you won't like the <span style = 'background-color: #dae8f4'>fentanylspan>. I went from the Ms Contins to <span style = 'background-color: #dae8f4'>fentanylspan> a few years ago & honestly it was the BIGGEST mistake I've EVER made!!! You build up a tolerance to the <span style = 'background-color: #dae8f4'>fentanylspan> quickly, it's 80x's stronger then morphine, 50x's stronger then heroin, & can be quite dangerous. PLEASE DO YOUR RESEARCH BEFORE TAKING IT!!!!!
I would rather deal with my pain without the patch, then the <span style = 'background-color: #dae8f4'>fentanylspan> running my <span style = 'background-color: #dae8f4'>lifespan>. I feel a sence of freedome and pushing on. Hope the helps someone..
This is what I've found - the <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>fentanyl</<span style = 'background-color: #dae8f4'>span</span>> patch has an average of 17 hour half <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>life</<span style = 'background-color: #dae8f4'>span</span>> AFTER removal. The actual range listed was 13-22 - so it could be somewhere in between depending on factors like body mass and absorption etc. Safer to assume more than less tho, so I'll say 22hours. So even tho you take the patch off, the drug continues to circulate and work for up to 22 hours later.
<<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>fentanyl</<span style = 'background-color: #dae8f4'>span</span>> is itself a very shot acting medication, but in a patch it becomes a different story. You did not specify whether you were on oral or patch preparation. Once you take the patch off or stop taking the oral <span style = 'background-color: #dae8f4'>fentanylspan>, the withdrawals come rather quickly, but they do not tend to last for a very long time. It is still a horribly painful experience, but since it is washed out of the body quickly we are taking days, not weeks. There is really no easy way of detoxing from home.
Did the croaker give you a pat on the back and some words of encouragement? Because that is not help. The good thing about <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>fentanyl</<span style = 'background-color: #dae8f4'>span</span>> is that it has a very short half <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>life</<span style = 'background-color: #dae8f4'>span</span>>, so wd should not be as long as say morphine or heroin. Bad thing is that wd tends to be sharper and harder with a shorter half <span style = 'background-color: #dae8f4'>lifespan>. Go back to this "helpful" doctor and ask him for some real help.
I hear horrible things about the power of fentayl and also its half <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>life</<span style = 'background-color: #dae8f4'>span</span>>. Does going this low of a dose help at all and does the clonidine help at all?
<span style = 'background-color: #dae8f4'>fentanylspan> patches have a slow rate of elimination and the half <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>life</<span style = 'background-color: #dae8f4'>span</span>> can extend to 27 hours as the <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>fentanyl</<span style = 'background-color: #dae8f4'>span</span>> is slowly eliminated from the fat under the skin.You are still probably feeling the effects of residual <span style = 'background-color: #dae8f4'>fentanylspan> and when that is gone you will probably feel worse withdrawal.But maybe not if you are lucky. Keep on course and I hope everything goes well for you. <span style = 'background-color: #dae8f4'>fentanylspan> injection has a short half <span style = 'background-color: #dae8f4'>lifespan>,but the patches are designed to stay in the body longer.
After removal, serum concentrations of <span style = 'background-color: #dae8f4'>fentanylspan> decrease slowly due to absorption of residual drug concentrations in the skin. The average half-<<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>life</<span style = 'background-color: #dae8f4'>span</span>> during transdermal application is 17 hours. Not surprisingly, this can vary considerably among individual patients. I think the question is not how much longer does this last? I would ask why are suffering?
I don't personally have experience with either drug but there are many on here who do so hang tight. I do know that the subs have a very long half <<span style = 'background-color: #dae8f4'>span</span> style = 'background-color: #dae8f4'>life</<span style = 'background-color: #dae8f4'>span</span>> which in turn makes the withdrawls very long and drawn out. The withdrawls from the fentynal should be nothing com pared to those. And the severity of the withdrawls depends on length of use and how much you used. So four months of use should be fairly easy withdrawls. Hang in there cause you are doing great! Good luck to you!
