-) What would the conversion have been from 50mg of oxycodone to fentanyl???? Thanks and take care, have to run now. Check in later.
Fentanyl is a horrible drug and is 80 times stonger that morphine. I did a conversion once when I found a table online and was shocked to find out that the 100mcg patches I was on are equivalent to over 200 mgs of oxycodone. That's some bad stuff to get off of and there is no easy way that I have found. I had the cheap mylan patches (flat and not jell filled) so I ended up cutting them so I wouldn't get the full dose and tried tapering a bit.
Feeling weird weird on these and thinking it's just the start up feelings from the Fentanyl. I'm also on on Celexa and that apparently is not a good combo. So i asked the Doc to get off the Fentanyl 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 Fentanyl. So my question is what do i need to overlap 75mcg off fentanyl?. do i need to go to Percocet or something else to not have the whidrawls coming back ?.
I've been undergoing a morphine to fentanyl conversion since January. This is being done against my will. I was stable on 90mg. morphine 4x day for over 10 years, last August 2012 my dr. informed me my dose was too high and he would no longer prescribe it for me. He was a new dr., my last one left Kaiser. Started decreasing my morphine monthly, it didn't go well. Pain way up, withdrawals, overall sadness. Finally in Jan.
Have never abused my meds Am presently on 60 mg. oxycodone every 4 hours (round the clock ... don't sleep due to pain.) Also was on 75 mcg. fentanyl every 48 hours. Just went to 50 mcg every 48 hours. Not sure how that will work. (I asked to decrease meds.) I've started cutting back on my oxycodone as well. I am definitely having withdrawal symptoms. I had the beginning of withdrawals once and it was horrendous (due to script late in the mail.
Would appreciate any folks who actually have changed from fentanyl to methadone for chronic pain management comment on the experience and effectiveness. Very briefly; I have a messed up spine from car crash years ago and will need either fusion, implant drug pump or stimulator within months for spinal stenosis that has not been resolved with conventional treatments, X-stop, P.T., acupuncture, etc. Pain is unbearable without opiate drugs.
I am on 50 mcg's of fentanyl what would the conversion be to Butrans? Thanks for the information.
I have been going to a pain management/spinal doctor for the past 2 months and am on Oxycodone, Kadian, Neurotin(sp?), & have just started the 12mcg patch of Fentanyl today (5/8/09). I am wondering what can I expect from this patch - the good, the bad & the ugly? I am not a newbie to oral pain meds as I was in a pretty bad car accident 11 years ago where I crushed part of my knee & messed up my leg. But, the pain patch thing is totally new to me.
wow, after reading all of these posts, I will stick with my oxycodone! My doctor mentioned the fentanyl patch in one of our visits and I said I would think about it and he did not bring it up again. This stuff sounds really scary!
Hydrocodone (Vicodin, Lorcet, etc) 7.5mg.............Hydromorphone (Dilaudid) 37.5µg............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 also wonder what the conversion dose of Fentanyl is for the 200mg of OC you were on prior to the patch? It may be worth looking at that and that may well be why you are feeling nothing yet with Fentanyl? It's also vital to ensure that you get full adhesion on your skin so you can correctly absorb the medicine so make sure it is sticking correctly. I have found Fentanyl EASILY to be the best big-dog med I've ever taken although there are many here that feel differently about it.
Will I need more than the two Norcos per day directly after application of the patch due to the time it takes for the fentanyl to hit the system? I have researched quite a bit and I have found the "conversion" tools to try to understand what a "like for like" I am dealing with, but I really don't understand the charts. I really appreciate anything you can tell me on this. I am, of course-a bit afraid to start the new patches not being sure about the Norco dosage to stop.
The Fentanyl, which I'm on for my Long-Acting Med, is approximately 80 times stronger than Morphine. The Oxycodone (I use Percocet 10/325's for my BT Pain) is not as strong as the Fentanyl. Which meds are you on for your pain? As I said above, I'm very happy that you have found this site and I hope that you will enjoy the support that we offer here for you!!

My pharmacist actually checks the conversion on their own. Fentanyl is a very, very strong medication. I would think 12 mcg of Fentanyl would cover 5 10/325 mg of oxycodone. The patch does take a while to kick in when you first put it on. Even though you are on the lower dose, Fentanyl is something like 80 times stronger than morphine. Remember, too, that if for some reason you do go into withdrawal, you can always call your doctor, even on the weekend.
You mentioned feeling like you were in withdrawal, and it's possible that being at the 25 mcg. of Fentanyl and not taking the oxycodone is causing some withdrawal. But, again, this all needs to be talked about with your physician. Try to see if you can get in to see him this week or at least talk to him by phone. It is often by trial and error with things that we find the perfect (or near perfect) combination of medications.
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 ****.
One site indicates that 18 hours after removal of transdermal fentanyl patch, approximately 10 mg of oxycodone every 12 hours can be substituted for each 25 mcg per hour of transdermal fentanyl to start. I cannot verify the accuracy of the site though it sounds about right. Trust your physician to make this decision.
I ran the calculator for you by converting 120 mg of oxycodone administered via 80 mg + 40mg of Oxycontin daily and the fentanyl strength computed is 50 mcg/hr. This calculator is VERY conservative when converting oral opioids to Fentanyl TD. So I also entered 4200 mcg and had it convert back to oxycodone. Doing this shows that 175 mcg/hr is equal to a total daily dose of oxycodone of 210 mg.
Converting Fentanyl to equal 360 mg of Oxycontin with the opioid calculator results in 300 mcg/hr. This is the largest dose conversion that is shown in the fentanyl prescription leaflet that comes in the box with the medication. So your doctor's thoughts that you need to keep going up on the Fentanyl patch are CORRECT. There is another option for you.
In summary, unfortunately the daily dosing amount of Opana ER is not equivalent to the oxycodone daily dose taken before the conversion and more specifically, LESS oxycodone is taken now through the adminstration of Opana ER. Keep in mind that all of the information provided is based solely on the science of pharmacology and it does not tell anyone how to take their medications prescribed by their doctor. Medications should always be taken per the schedule provided by the physician.
And the dangers with Fentanyl, especially as it comes in Micrograms and not milligrams...it makes conversion even more tricky. We live in a world where there are people who scour the internet all day and read sites like this and use them in ways that they shouldn't...I am NOT trying to say you, or even the OP...but this is why I don't post things like the conversion tables or things in that way as I don't ever want to say that it's ok to use them ourselves... So...
i have been using oxys for years then it went to oxyneo worst medication ever with break threw meds of percs then i couldnt afford the oxyneo anymore as they were a killer in price and they after years of using them for cronic pain that hasn't got any better for years oxys started rotting my teeth hurting my body in many ways and my mood swings were crazy my doctor put me on fentanyl patchs 25mcg did nothing i was taking 80 percs a month with 200 oxys a month finally i went to 50mcg with percs
I am in pain management x 1 year and currently on Mylan Fentanyl Path every 48 hours along with Oxycodone x 30 mgs. a day. I was the victim of a drunk driver. I am always here to help answer questions from any member and ask a question if I need information.
I too use the Fentanyl 75mcg Patch along with the Oxycodone. There are many conversion tables available through the internet and Doctors also use theconversion method when finding the right dose for you. Fentanyl is one of the strongest pain meds on the market and it will take a high dose to reach the equivalency. For instance: 77.5mcg of Fentanyl= 150mg of Oxycodone per day. This calculates to approx. 2, 80mg of Oxycontin per day.
All I know is that they will use a conversion chart to do that transition. I asked the PCP what to expect, and she said that I would feel some discomfort for the first couple of weeks but that it wouldn't be bad. She really wasn't convincing though. I have been on 75mcg/q48hrs for 4 years. I am sure that I am very dependent on this stuff. Why all the fear you may ask??
a good NEW behavior, eh?...however, have a look at this conversion chart, ok? Conversion table other drugs equivalent to sub/bupe Jul 24, 2008 - 8 comments #Pain Killer Equivalent Doses (Oral) 1.2mg.............Buprenorphine (Bupe) 200mg............Codeine (Tylenol 2, 3, 4, etc) 30-60mg.........Diacetylmorphine (Heroin) (orally it = morphine, IV/IM/insuffilated it's 2x as strong) 100mg............Dihydrocodeine 30mg..............Hydrocodone (Vicodin, Lorcet, etc) 7.5mg............
3 months ago an MRI revealed buldging discs (L4/5 and S1) and I have been taking Oxycodone and receiving epidural injections (which do not help). The pain is only getting worse all the time. My Neuro said I cannot be helped by surgery, but I have made an appointment with an Ortho to confirm that opinion. A few weeks ago he added Morphine to my meds, but the pain is simply increases every day.
Ask your doctor to do a liver function test (AST/ALT and ALP) while everyday on paracetamol and see for yourself. On the other hand, morphine, hydro/oxycodone (without paracetamol) in the doses you're taking, are highly unlikely to cause any liver toxicity.
The major discovery is that the classic opioids like morphine, oxycodone, fentanyl, and Dilaudid (hydromorphone) break down into metabolites that are 'hyperalgesic', that is, molecules that can actually cause pain when they accumulate under conditions of chronic administration. This might explain the experience of switching to more and more potent opioids which in turn produce more and more hyperalgesic molecules, and so a vicious cycle develops. Methadone is different.
Here's a conversion chart that will show you how much sub is equivilent to fentanyl and dilaudid. http://www.medhelp.org/user_journals/show/18499/Conversion-table-other-drugs-equivalent-to-sub Not knowing how much dilaudid you were on, it's hard to calculate the conversion dose. But I surely wouldn't ask for an INCREASE in your dose.....16 mg is PLENTY, imo. Your body is working VERY hard to adjust and it's not been a week yet on the subs.
