Fentanyl dose equivalent
Common Questions and Answers about Fentanyl dose equivalent

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 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.
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.
20mcgs of dupe is not enough to cover 40mgs of methadone. Also, the partial agonist affect of dupe leaves some people feeling odd anyway, so taking too little is adding to that affect. From what I have studied, 1mg bupe is a closer dose to an equivalent.
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.
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.
Ni nubbin,
The reason that you are suffering the withdrawals is because you were put on way to low a dose of the Fentanyl. When you have been on the mthadone 40 mg's for 15 years and are switched to 25 mcg's of Fentanyl Patches you are way under-dosed. :( If your doctor had done it properly you wouldn't have had nearly the trouble and withdrawals that you are going through now.
I'm so sorry that this happened to you!!
Hi. I am a chronic back pain sufferer - have been for 16 years. Was put on Tramadol in 1998 after 2 back surgeries. Stayed on low dose for a good number of years. In 2005 pain started getting worse and Tramadol was upped until I was taking the "maximum" dose - 400mg a day. This wasn't enough to stop the pain and although it didn't really change things, pain wise, I was taking 600-700mg a day.
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.
What are you taking? The people here are really really helping me!

A little more research and I found that the 50 Fentanyl Patch is the equivalent to approx.134 mg of Morphine (and of course that is what the Ms-Contin is). So it's no wonder that you are in so much pain. I sure hope that you can get some help from him tomorrow.
I'm really sorry. Good Luck....Sherry
Why don't you try a nice hot bath or shower as that might relieve some of your pain. Wish I could help you more.
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...
Fentanyl can be very difficult to come off. The withdrawals seem to be harsher and last longer than other opioids. But you are lucky to only be at 12 mg over 4 weeks. Did your doctor have you on something else before he put you on the Fentanyl? I ask that because Fentanyl isn't normally used as a first-line drug for pain. If you were on something else, that would factor into your withdrawal.
You can read lots of withdrawal hints over on the Substance Abuse forum.
Three months in, the honeymoon with methadone was over, so my doctor figured the equivalent dose on another narcotic might do the trick. I was prescribed the Duragesic patch, (also known as fentanyl) a treatment typically reserved for end-stage cancer patients. The advantage of the patch was that it maintained a steady dose of the drug around the clock, but the dose she switched me to wasn't exactly equivalent.
Hi fahadali2008, hope you are feeling better and able to have some sleep? Since when were you taking Lexotinal for sleeplessness and how much useful was it? Had it been prescribed by a doctor? Can you say the reason for stopping the use of this drug completely? Did you have any serious side effects of the drug? It is better you consult your attending physician or consult a sleep specialist before abruptly stopping the drug to be advised on the alternate medications.
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.
