Fentanyl dose equivalent

Common Questions and Answers about Fentanyl dose equivalent

actiq

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 Fentanyl 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 Fentanyl 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...
I'm presuming you're talking about the fentanyl patch? Fentanyl is a very strong pain med, as I'm sure you're aware. It does come in other forms - pills, IV and "lollipops" - perhaps one of those other forms would be less expensive for you - I'm not sure. The main thing is, none of those are as long acting as the patches.
I have a lot of experience with fentanyl patches but i must say you are on an incredibly high dose. Usually even in terminal cancer patients 300mcg/hr is the ceiling dose. 400mcg/hr is the equivalent of 960mg of oral morphine!!! (a 50mcg patch is equivalent to 120mg of morphine). That is truly an astronomical dose!!! Tapering from fentanyl patches is difficult as they cant easily but reduced in small increments.
Fentanyl (not sure on this one, anyone know the oral dose equivalence for Fentanyl?) 4mg................Levorphanol (Dromoran) 300mg............Meperidine (Demerol) 10-20mg.........Methadone 30-60mg.........Morphine 20mg..............Oxycodone (Oxycontin, Percocet) 10mg..............Oxymorphone (Numorphan) 200-300mg.....Propoxyphene (Darvocet) 150mg............
I was tarted on the 25mcg patch and was titrated up to the 100mcg which was considered my therapeutic dose. I was on Methadone prior to the Fentanyl. Fentanyl is VERY strong, they say almost 80 x stronger than morphine and the Dr will normally start you on a lower dose to see how it is tolerated. It does NOT work well for everyone and I didn;t really start to feel any pain relief at all until I was on the 75mcg patches.
I am currently 23 weeks pregnant, on 100 mcg per 2 days of Fentanyl & due to a miscalculation by my dr have NO meds for at least 3 days. How dangerous is this to my unborn child? How bad is the withdrawal gonna be, how long will it last & what withdrawal symptoms should I expect? I'm EXTREMELY scared for the safety of my unborn child as well as myself. I have 2 other kids that I am raising on my own & need to know what to expect. PLEASE HELP !!
So you should be able to stop the patch and take a vic as needed. Duragesic (Fentanyl) withdrawl was the most painfull withdrawl I ever had. At one point I had a 160mg oxycodone habbit and it wasn't nearly as painfull as a duragesic 25 withdrawl (and I had only been on it for 30 days). My doctor messed up my appointment, leaving me 2 days from the time my 30 day supply was up until the next appointment.
So your total morphine intake per day is 105-150 mg. The 25 mcg/hr patch is equivalent to the morphine dose range of 60-134 mg and the 50 mcg/hr patch is equivalent to the morphine dose range of 135-224. So either the 25 or 50 mcg/hr patch would give you dosing within the range of the morphine you are taking orally right now. Given that your morphine dose falls on the lower end of the 50 mcg/hr patch, it is probably wise to start off on the 25 mcg/hr patch to see how you do first.
Can someone please tell me what recommended protocol (Generally Speaking) for reducing fentanyl 50 mcg safely to another medication that works better in my wife's case - lower dose of generic equivalent of Oxycontin. Could you also recommend a generic equivalent of the drug Oxycontin we simply cannot afford Oxycontin it is way too expensive...
com/analgesics.html#fentanylpatch On this site they convert various fentanyl doses into an equivalent morphine dose. It is widely accepted that morphine and hydrocodone are fairly similar, almost identical in terms of potency (http://www.globalrph.com/narcoticonv.htm) although i consider this comparison too generous and see hydro as being more akin to dihydrocodiene So, 12mcg of fentanyl is equal to 22.5mgs - 65mgs of morphine per day which in turn is equal to the same amount in hydrocodone.
My GP (who was furious that I'd been put on Fentanyl in the first place and without any information) has switched me onto 100mg (25mg x 4 daily) of MST (Sevredol) which is supposedly the equivalent dose. I'm only on the first 24hrs and feel as high as a kite. I feel completely nauseas, headache and spaced out. I'm very tired but not sleeping. To be honest it could be (and has been) worse but I'm just feeling low - like at the bottom of a very steep hill.
People just need to realize that being on a 25ug/hr patch is still being on a pretty decent dose of fentanyl.....or opioid, for that matter. As far as fentanyl being like morphine, they are alike in their affinities to the mu opioid receptor and that is basically it. Fentanyl is metabolized into an inactive metabolite (norfentanyl) where as morphine is metabolized into one active (m6g) and one inactive (m3g) metabolite. And, heroin is metabolized into morphine.
I love the Fentanyl patches that I use to manage chronic pain! May 2012 is the first month on the patches! I am currently using my 6th patch which I will change on May 13th. The extended release pills that I have previously taken for management of chronic pain have caused severe constipation. I had tried every over the counter remedy out there. At the end of treatment, I was downing miralax every evening before bed with no results just extreme bloating.
What is the dose of the fentanyl patch that you are applying? Is it the equivalent dose of what you are currently on? If not, you may not get equivalent pain relieve from the fentanyl patch.
they wait and check you out.. maybe adjust your dose. some people experience a fuzzy feeling until their dose gets adjusted.. some nausea.. the most important part is to be in WD when you go to the doc.. so call him and check out the site suboxone.com they walk you throuhg the whole thing.. i gotta go be back later today.. I will check in with you then... Call your doc asap!!!!!!
Now my doctor prescribed the Fentanyl Patch 25, and I am terrified to use it. It says you have to be *opioid tolerant* which I am not. Also I take the Ambien and Xanax. Doctor said *be careful* but still, I am terrifed after reading the drug side effects. I'm scared, and my hubby and son are mad at me because they said I *won't try* anything. PLEASE HELP--what do I do? Thanks so much.
Wow, what a shocker eh? Now those are the wd's I'm talking about! Kinda get's your attention when it hurts down to the cellular level. I don't usually do this, but I looked up fentanyl conversion to oxy. I'm not a professional or trained, " this is my disclaimer". It looked loosely like 75mg's of fentanyl is "roughly" equivalent to between 112.5 and 157 mg's of oxy. DO NOT take my word for it!
I have not noticed any improvement in my pain, whatsoever. Does it take time for the MS-Contin to work, or is it too low of a dose?? I do not have any "breakthrough" pain medication. It doesn't help that the insurance is giving me a bunch of bull-crap and I have missed my second dose of Humira (medication for rheumatoid arthritis, which was really helping!). I am considered opiate-tolerant by some of my doctors. Right now I am just in agony.
Important to add that I am in England-so meds may be different! I was on Fentanyl patches 37 mcg and 3 oxynorm 5mg per day for 5 years. I found that the tablets were becoming a problem in that I would save them for times where I felt insecure or needed a bit of courage. I had weight loss surgery and have lost 230 lbs. I am in therapy as well for body issues and feelings of self loathing. Issues which need to continue to be addressed.
You use it to convert your fentanyl dosage to an equivalent morphine dose, and then find the equivalent morphine dose to oxymorphone, Generally when converting between opiates, doctors will reduce the new medication strength by a certain percentage to account for incomplete cross tolerance, which is a boost in analgesia you get from rotating from one kind of opiate to another. You can find equal analgesic tables, and apps for calculating equivalent dosing online.
I was shocked to find out that the 100mcg fentanyl patch is equivalent to over 200mg of oxycodone per day!! HOLYCOW! I wish I was smarter BEFORE I let the doctors put me on that ****.
so thats 180mg per 24 hours, and i was wondering if anyone knows what the equivalent is in heroin. ive just come off fentanyl patches onto the morphine so i can taper down, my aunt who died was addicted to heroin so i know a bit about it so i just wanted to know the equivalent so i can understand roughly how much morphine im taking. thank you to anyone that can help. kind regards, carrie.
Wow Mollyrae I can imagine you were in pain and w/d as the 20mg Oxycontin can't compare to the dose of Fentanyl your on. I think the dosage I am prescribed would do well for you at least to begin with and go from there. 8 mg every three hours sounds excessive I know but as I said I am only taking them every 4 to 5 hours. I am going to keep the paper prescription of oxycontin and not fill it unless something changes and have the Doctor change it to the ER formula of Hydromorphone.
A person taking a 50 mcg/hr Fentanyl patch is the analgesic equivalent of 100 mg/day of orally administered morphine sulfate. Oral methadone is 4 times more potent than oral morphine at lower doses, but 12 times more potent at higher doses. 7.5 mg of hydromorphone (Dilaudid) is the analgesic equivalent of 20 mg of oxycodone. The half life of a painkiller has a direct impact on the onset and duration of withdrawal symptoms.
You will want to keep your Vicodin on hand for BT pain but you shouldn't need the number of pills that you were taking before once they get your dose correct on the Fentanyl. Usually the first dose of Fentanyl that they start you on isn't the one that you actually need. They will work you up slowly so that your system gets used to the strong medication. So hang in there, because once you get on the correct dosage you will feel soooo much better. There will always be SOME BT pain at some point.
Hi & Welcome, The doctor has got to take you off of the patches slowly. that is a very high dose and you will have problems coming off of it cold turkey. I would go back and talk with him and tell him you need help reducing your dose. they make the patches in smaller doses. that is the way he should be taking you. Let us know how you are doing.
Everyone's reaction to opioid medications is different as well as the development of tolerance is different from one person to the next. There are many other effective opioid medications for pain management other than Fentanyl, Morphine, Vicodin, and Oxycontin.
My mother who has cronic back and shoulder pain is being taken off of fentanyl 100mcg patch and 7.5/500mg and being put on morphine 60mg 2x daily and then morphine sulfate 15mg every 4 hours for breakthough pain. What I'm wondering is there going to be withdrawl or is the morphine going to have enough of the same stuff in it. If not what kind of withdrawl systems will there be to watch for.
The dose of MS Contin is not equivalent to your current dose of Oxycontin...by a long shot! Taking 15 mg of MS Contin 3x a day is equivalent to taking 10 mg of Oxycontin 3x a day. I hate when doctors sneak in a significant dose reduction through a conversion to another opioid! Even factoring in a cross tolerance factor, your dose should have been at least 30 mg 3x a day.
