fentanyl conversion

Fentanyl conversion is not a atraight conversion from one opiate to another. Because the delivery systems are very different- oral versus transdermal. It is very likely the conversion dosage rate is fine- however since you are going from oral meds to transdermal - it needs to build up in the bloodstream and the tissues so that you are receiving a steady dose.

Conversions from one opiate to another are typically done reducing the new opiate dose by 20-30% for cross tolerance. Converting from fentanyl back to oral pain meds is a difficult conversion, and may require adjustments by your doctor. Do not adjust the dosage on your own or take more than you are currently prescribed without your doctors permission and guidance.

My moms doctor took her from taking 4 percocet 10s a day to fentanyl patch 50 mg every 72 hrs...is this normal? She has rheumatoid arthritis.

Hi, I am not sure of the exact conversion rate but Fentanyl is 40 times stronger than morphine so taking that into consideration it sounds correct. Also doctors normally start Pt's out on the 25mc of Fentanyl and then titrated up as needed. Rarely is a Pt started out on higher doses. This way your put on the lowest amount that will treat your pain. Tolerance issues being considered the lowest dose is the best. I hope this answers your question.

Just wanted to ask if anyone had any experience with switching methadone 95mg once daily, to fentanyl patch 100mcg Hour patch? or know the methadone mg fentanyl dose equivalents?

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...

Hello Novermhead, You've asked a good question. Oxycontin is a sustained release medication and I am surprised that you are taking four, 40mgs tablets per day. According to the conversion charts that I normally refer to the fentanyl patch would need to be 125 mcg to equal what you are taking now, which would be delivered over a 72 hour period.

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.

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??

There really is no exact equivalent, but i can guarantee you that 20mcgs of bupe doesn't cover 60mgs of methadone, for anyone I have met. Maybe in someone's theory, but I have read it is closer to 1mg dupe is good for 30-60mgs of methadone. I was at about 200mgs methadone and 8 mgs bupe was about right, which is half what my doctor prescribed, but that is 50mgs methadone to 1mg bupe, was still a little off, but stabilized in a couple days.

It may be that the conversion to fentanyl was too high a dose... given your description of symptoms, they aren’t typical withdrawal, but sound more like the fentanyl dose was too high.

I have read many different equianalgesic conversion tables but most are just calculated guesses. Fentanyl is the most difficult of drugs to convert in this manner and many equianalgesic calculators dont even botherl One i believe to be fairly accurate can be found here http://www.thedrugmonitor.com/analgesics.html#fentanylpatch On this site they convert various fentanyl doses into an equivalent morphine dose.

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.

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.

t know where else to put this, but I was recently switched from Morphine 60mg ER to the Fentanyl Duragesic patch. I thought the weird flu like symptoms might be a result of the new drug, but apparently it has to be withdrawal from the Morphine. I'm kind of miffed neither the doctor nor pharmacist even mentioned this could happen. I was naive and thought the new medication wouldn't create an issue with the switch, I was wrong.

i have been wanting off this fentanyl patch for months now and finally had the courage to talk to the doctor about switching to an equivalent ER opiate. i am currently on the 50 mcg patch every 48 hrs. she wrote a script for 10 mg oxycontin 2 times a day. i asked her if she had a table for conversion she could look at and she said 'yes' because i was NOT wanting less pain relief. actually, have been needing more the past few months.

I certanly wouldnt want the dose too be too low, and have ANY withdrawl reaction from stopping the Fentanyl and percocet, but a dose that would be at least pretty much the equivelent and give just as much relief as the patch and percocet 10/325?

I have been prescribed fentanyl and it wouldn't stay on me when I was active bc I'd sweat so my Dr changed me to Butrans 15 mcg plus 10mg of oxycodone for bt. I have 2 nerves left and right that are damaged , spinal stenosis, degenerative disc disease, and no fluid between S1-L5... Upon that I have a bakers cyst in my knee and damage to my left hip... I have been on 50 mcg of fentanyl and 6 ten mgs a day for btpm. My tolerance has become high bc I have been in pain since 1999.

I have recently found out that I have a few things going wrong with my back. 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.

Hi gracie255, First, I want to welcome you to the PM (Pain Management) Forum and let you know that we are glad you found this Forum. We are all CP (Chronic Pain) Patients that help each other with our own expertise and experiences that we have developed through our own CP Issues. I read your Profile and I will add you to my Prayers!! Bless your heart, you are such a Brave Lady!! There's really not much of a comparison between the 2 meds.

My PM doctor was prescribing 50 mcg fentanyl patches to be applied every three days. They were going to give me a urine screen, but I have interstitial cystitis and a neurogenic bladder. I was unable to provide enough urine, so the nurse gave me water to drink. I was on my way back to the bathroom, when someone other than the nurse stopped me to say I was having a saliva test. I went back to the room and continued to drink water, because I have dry mouth from taking Lyrica and Lamotrigine.

They are great over there and can probably give you some first hand knowledge. I looked up a conversion chart for Fentanyl. I found a few charts and they are all basically similar. 315-404mgs of morphine is equivilant to about 100 mcg of fentanyl. Thats oral morphine. The IV morphine chart is different. I do know that fentany is one of the strongest opiate medications available.. I believe it is much stronger than oral morphine. At least that is what I have heard and read.

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.

If your doctor does it properly, there should be no withdrawals. It was a big fear of mine as we switched meds a lot. But they have a conversion chart they use so it's not usually an issue. Also, talk to your pharmacist. They have a wealth of knowledge and can help allay an fears. Having a good relationship with your pharmacist is nearly as important as having a good relationship with your doctor. Which narcotic are you coming off and which are you switching to?
