Of course I remember you and our conversations:)

I really am not trying to argue agaisnt you...I promise...

I just think that there are hundreds of people who are viewing these posts that don't come on to talk about them and unfortunately, lots of those people actually may try to figure out on their own what type of medicine to take and how to take them...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...that's the main reason I am much more stringent in what I discuss online out in the open...

I was just concerned in the way that the OP wrote the first thread...as it "seemed" they were asking us on how to switch over medications..That's why I just wanted to refer them to their Dr...Just like they weren't understanding what breakthrough pain or medicine was...this seemed like there is not good communication between the OP and their Dr...

Again..I truly understanding from where you are coming...I'm just a lot more cautious about things online and what I write...

I hope that the OP is doing well and we get an update about their Dr. appt. as well as I hope you are doing well Femmy! Hope the Opana has been working for you:)

I know you don't mean to argue with me...ever.  I think we are just both different individuals and that is okay.  I understand that hundreds of people view our posts but with a simple google search or two, one can get this exact same information.  In other words, this is not the only place to get the conversion information.  Now, I will not provide conversion info for methadone...ever!  That opioid is completely unpredictable as it builds up in your system and even the conversions that are out there are very risky to go off of as everyone's metabolism is different and with methadone, the conversion is not straight forward at all.  Many doctors start patients off on a much lower dose than the conversion states and then keeps them there for awhile and then tiny baby steps are taken to make sure the person still wakes up to see another day each morning.  I have decided that I will never accept a prescription for methadone.  I have read great things about it and that it is superior to other opioids in terms of pain relief but it is just too dangerous for me!  It makes sense for those addicted to heroin or other opioids and were taking outrageous dosages of their drug of choice to maintain a high or normalcy.  The risk of methadone to them is much lower due to the massive tolerance they carry.  I don't have anywhere near that tolerance.  But I do know that methadone has helped a lot of people and many are taking it safely but I don't feel comfortable providing any dosing info for methadone nor trying it myself.  

I agree that Fentanyl is tricky as well, not nearly as tricky as methadone but tricky nevertheless.  But given what the original poster asked, I believe I provided a good ball park range of Fentanyl dosing with the caveat that the initial dose may come in slightly lower than this requiring a few titrations to minimize side effects.  

I fully respect both your and JayBay decisions to not provide dosing information to the OP.  But I felt different with regards to my answer to the question for reasons discussed earlier.  I believe it is great to have different opinions and views in this community to provide OPs with many different solutions or thoughts to their questions.  A rainbow pot of answers is better than the same cookie cutter answer from 15 people.  So I believe you and JayBay also provided valuable information to the OP.

The Opana ER is still working very well.  I am just having issues with increasing my activity level.  While sedentary, my pain levels are about 1-2 and 10 mins into an activity, the pain levels spike to a 7-8 but if I stop the activity my pain levels will immediately go back down instead of resonate the way they used to.  But my breakthrough pain medicine is not providing additional coverage such that I can continue with the activity.  I have to stop either way to get my pain levels back within manageable levels.  I am going in for another injection on the 14th.  It has been 6 months since my last injection as getting my gall bladder removed in December interfered with that injection.  I had another lumbar MRI completed a couple of weeks ago and it says that I have osteophyte complex (bone spurs), spondylosis (osteoarthritis), spinal stenosis (caused by the ruptured disc at L4-L5), permanent ligament thickening, new nerve impingement at L4-L5.  The L5-S1 disc is completely dessicated as well as continuing to cause nerve impingement.  And I recently found out I have mild scoliosis of the thoracic and lumbar spine.  Much more than just the disc issues the last MRI documented.  So I honestly don't know if the injection will really help or not...we'll see.  My PCP wants me to consider a spinal fusion...I am not too sure about that as I have heard horror stories of failed back surgery syndrome.  I have not discussed the new MRI findings with my spine orthopedic specialist yet but will be next month.

Hi Punky,

Thank you for the response.  A lot of folks with chronic pain in the US are being switched to Opana ER.  I am not sure if you have heard of it before but it is oxymorphone in extended release form.  I am on Opana ER, 30 mg twice a day; however, I was switched from Morphine ER.  I have never taken Oxycontin before.  

The oxycodone in Oxycontin is metabolized by the liver into oxymorphone, and oxymorphone is 2 times stronger than oxycodone.  With the Opana ER, I have read that chronic pain patients either love it or hate it.  I am one of ones that absolutely love it.  Opana ER has provided me the best pain relief I have had in years.  I tried the generic oxymorphone and it was not as effective...by a long shot.  I did some research and discovered that the brand Opana ER tabs have a new TimerX-N technology built into them such that they provide true 12 hour dosing.  This technology is only licensed to Endo pharmaceuticals for the manufacturer of Opana ER; therefore, the generic drug company (Actavis) does not have this in their pills.  I talked with my doctor about this and he confirmed my research was true.  The morphine I was on and also the generic oxymorphone only lasted 6 hours.  I should also mention that oxymorphone is 3 times stronger than morphine.  

Given your Oxycontin dosing, you would need to take a 40 mg Opana ER tab 3x a day as 40 mg of oxymorphone is equal to 80 mg of Oxycontin.  You may look into the regular Opana IR tablets for breakthrough pain.  I take percocet for breakthrough pain but I have read that the half life on the Opana IR tablets are 6 hours versus 2 hours for percocet.  I am thinking of asking my doctor about them at the next appointment.

I understand your concerns about Fentanyl as I too have those same concerns.  I have heard that even with the tegaderm supplied by the pharmaceutical company to hold the patch in place that they still sometimes fall off and you are right, additional patches are not provided to cover for these circumstances.  Many online have stated that they stopped taking showers and switched to sponge baths just to keep the patches from coming off.  If you go with the Opana ER, the majority of your dose will still be in pill form versus all of it within the Fentanyl patch such that you wouldn't need to worry about ending up in pain should the patch fall off.

Wishing you the best with everything and keep in touch and let us know how you are doing.

Thank you femmy29

You got it RIGHT, I am not running out a buying them i was just curious as to what the dosage would be and YES my Dr is the one who WILL decide what I will be taking. As for break through, dunno..........
i wear the patch for 2 days and take the oxy 3very 8 hours, but now with the new oxys i want to change. we do NOT have them here in Canada yet, and i am nervous after reading all the horror stories from all the ppl in the USA. i WAS 1st on 3 x80 and 1 x 40 mg of oxy and he took the oxy 40's away and gave me the patch to wear = 1 x 25mcg and a 1/2 a 25 to wear = 37.5 mcg fentynal..............as for pain, I have Fibro, cronic back pain, arthritis in my entire body, plantar fasitiis, carpel tunnel, tendintitis, sciatic nerves are a complete mess of pain......lets just say my entire body IS FILLED with pain ! And YES I was just asking about the fentynal, cause I am not sure which way i want to ask my Dr to go, which would be the best = to MAYBE go on morphines and NOT go on the NEW oxys and just keep the 21 patches amonth @ 25 mgs OR ask to just go on fentyanl. YES he does have the final say, but i also like to be in control and IF I NEED more , then with a pill I can take a bit early or later BUT with the patch its on , then its on and IF were to fall off due to sweat, etc,.,....they will NOT replace and think maybe i am just wanting another, so I was just asking a question as to what it would equal with what I am on now to just fentyanl. but i think i would rather go to morphines 3 x a day and keep the patch the way it is...........i have my appointment soon, BUT if we still have the old oxys here on March 18th , then I WILL still get them,till the new ones get here and I want NO part of them..............so in the end i will let you all know what happened , Ok............i honestly was just curious what the total dosage would be on the fentanyal IF i were to go only to that...............I thank You all

Haha!  Yes a pitch fork or two or three came my way which I expected.  The website I posted has a major disclaimer listed on it and it also does state that the conversion is done on the conservative side so at least a 25% cross tolerance factor is applied if not more.  

Main point is no one can order fentanyl patches on their own.  A doctor would need to place the prescription; therefore, I don't believe any real harm has been done.  She simply wanted to get an idea of the dosing required of fentanyl to equal the oxycontin she is taking now.  It is not like the original poster can just run to the local drug store and buy 3 fentanyl patches and slap them on.  Now if the original poster decides to buy them off the street, well that is their perogative and whatever happens, happens at that point.  It sounds as though the original poster is a compliant patient and will follow her doctor's orders regarding the switch from oxycontin to fentanyl.

I do trust my doctor and he is a very reputable physician that has been featured on the local news in our state but despite this, he did not apply a cross tolerance at all when he switched me from morphine ER to opana ER (you may remember responding to my post on this subject awhile back).  In fact, it was even more medicine than I was already taking in both morphine ER and breakthrough pain medicine in the two 30 mg opana ER pills I take per day.  The transition was rough but now I couldn't be happier.  But it was nice to know how much medicine I was getting in terms of morphine as I could anticipate that the medicine was going to be very strong and prepare accordingly.  He said that based on experience prescribing opana ER to other patients he knew the conversion guidelines put out by the pharmaceutical company were way too conservative.

No one is perfect even though many look to doctors as if they are gods, I certainly do not look at them that way.  They are all human and we all make mistakes time to time.  Additionally, when one picks up a prescription at the pharmacy, one should not assume the prescription is correct as there has been several errors that the pharamacists have made which have killed a few people and serious injured others.  The risk is very low that a mistake could occur but it is not nonexistant.  We as patients need to be cognizant indviduals.  When I get a prescription filled (especially if it is a new medicine or the pills look different, I always enter the pill information at http://www.drugs.com to make sure the medicine is as expected).

The original poster may also want to consider a morphine pump or a spinal cord stimulator as the dose of fentanyl is extremely large despite tolerance such that the side effects can become intolerable given dosing as high as this.

LOL...No pitchforks.:)

Just letting people know that those online conversion charts don't really account for cross tolerance even though it says you need to enter it in up to 25%....But most people have no clue what percentage to put in...

So....25% either way can be very dangerous when trying to figure this out for themselves...As well as body weight, metabolism, other health conditions, other medication one may be taking....

That is why I recommend that nobody, ever, tries to do this on their own..A Dr. is the only one that should be converting someone from one medicine to the other.

I do agree with knowledge being power...but we also have to realize that none of us are Dr.s....and they have gone to school for a long time, and have spent many years learning what they do. If we don't trust them....than why are we going to them?

I love my Dr. and trust him with my life. Just like my Neurosurgeon....My PM Dr. and I are actually friends outside of the office...We have sat and talked over many a coffee and lunch....

The biggest pet peeve he has is when people think they know more than he does by reading things online....a website should never take place of a Dr....(I don't think you are saying this....just stating in general)....

Any reputable Dr. will ALWAYS start a new medication on the low end....it will usually not show up on the conversion chart you posted as again...there are so many other variables that go into a conversion than what is listed on that website....

People react differently to every med....and someone could be allergic to a certain med and if they start on a high dosage...it could kill them....

I just warn that again...if someone isn't trusting their Dr. to do things the way they should....than they should find another one they do.

Maybe pitchforks will come back my way....LOL:)

Hi Punky,

I agree with what others have said that your doctor will decide what dosage you need to be taking of the fentanyl patch when you switch over from oxycontin to only fentanyl.

There is a great conversion calculator here:
http://www.globalrph.com/fent.cgi

I entered 480 mg of oral oxycodone as that is what you take every 2 days.  If you stick with switching the patch every 2 days, you would need around 250 mcg/hr of fentanyl.  This conversion; however, is probably based on switching out the patch every three days so you may need a slightly higher dose than that...like 300 mcg/hr.  That is  A LOT of fentanyl!!!  But I understand tolerance.  I am just no where near that intake amount.  You need to apply 3 patches at once as I believe fentanyl comes in up to 100 mcg/hr patches but there may be a 200 mcg/hr patch.  I did not include the 25 mcg/hr + 12.5 mcg/hr patches you are already on in the conversion.  

Someone is about to throw pitch forks my direction for providing this information to you but I believe knowledge is power.  I always check the conversions myself when I start a new opioid.  Just to make sure it checks out.  I still believe you need to listen to your doctor closely as you may need to start out on a lower dose of fentanyl at first and then titrate up to minimize any side effects introduced by an incomplete cross tolerance factor.

Keep in mind that you also may want to reserve some of the fentanyl dosage as oxycodone IR or some other immediate release medicine for breakthrough pain.  Fentanyl is not a breakthrough pain medication, it is for coverage of your baseline pain, not pain that breaks through the long acting Fentanyl...oxycodone IR, morphine IR, vicodin, opana IR is instead used for those events.  If you switch entirely over to fentanyl, you may find that you still experience breakthrough pain as the long acting medicine is not perfect in terms of baseline pain coverage.  In other words, you can keep increasing the fentanyl and still have breakthrough pain along with amplified side effects due to the large dosage.  A balance should be struck between a long-acting pain medicine (like Fentanyl) and a short acting pain medicine like oxycodone IR.  The split is considered "optimal" when a patient has only 1-2 periods of breakthrough pain a day.  

Wishing you the best.

I think you are misunderstanding what breakthrough pain and medication is...

Breakthrough medicine is not meant to be taken on a regular basis...That would be your maintenance medication....

Breakthrough pain is lets say you are at a 5 on the pain scale and you have a very busy day that you end up with a 7 on the scale...You would take a short acting medication that acts "quickly".....This would help control the pain and get it back to a 5....

This is what makes me more nervous for you if your Dr. is not explaining these things properly to you....or he himself uses Fentanyl on his patients for BT pain....

I've lived with chronic pain for over 11 years....I have had 3 cervical fusion surgeries on two levels....The last surgery they went in from the front AND the back of the neck the same surgery....

So, believe me, I know and understand chronic pain....

I was replying to your original post which was asking people online what amount of Fentanyl you should take...This is where I was saying that only your Dr. can provide that information. And was just letting you know that it's unusual for a Dr. to put someone on two types of long acting medication...Hopefully you were able to speak with him today...

May I ask what surgeries or procedures you have had? What type of pain do you suffer from?

Again...hope things went well today...

No no no,,,,,,,,,,,,,you have this all wrong !! 1st, i am only wondering this because i DO in fact HAVE MANY MANY types of pain.
and NO i do NOT walk in and tell my dr, what i want, geez! its just that this all is working for me and now i am only worried , cause of what i am hearing about the new pills and ALL THE MANY problems ppl ARE having with them, !!! The patch IS MY Breakthrough pain medication and its for every 2 days ! Also I have been on these for like 13 yrs and havent gone up on dosage, just got the breakthrough last yr. As you also know, ya build up  a tolerence to them as well...which was in my case.IF i was NOT hearing all the BAD things about the OP's, I would NOT even be here aslking questions. I actually DO have a gr8 dr, caring and NOT A PILL Pusher by no means, in fact he wants me on one or the other, which just made me curious as to the strength that would be , nothing more then that to why i am asking and wondering folks, nothing more/ I do NOT abuse, sell or anything else with my Meds. i take as directed as well. So, PLEASE Do NOT think of me as a bad person, I am just a person with alot of different pains who IS curious on a strength thats all. So, PLEASE do NOT Judge and Hang me for wanting to know something. Thank YOU,And I ALSO understand your concerns to my questions and why you would be wondering why i want to know, as YES I will be talking to my Dr. and at the end of the day, YES Is IS up to him on what and how much I get for Pain. Sorry IF anyone misread what I was asking here and NO I am NOT on to high of a dosage for the length of time I have been on these dam things, and last but not least..........i would rather be PAIN FREE AND to Never have to take another med for anything, but that will NEVER be the case for me.........i just get worse as time goes on, I can NOT even pick something off the floor, without having shooting pain up my tailbone into my back and up my neck............Just one example of one of the Many Pains I Suffer every single day.........................
thank you for your replies though.

From,
Canada

I agree with Jaybay....This is not for you or anyone on the internet to decide...It's actually very concerning that you are asking it this way as it seems like you go in and tell your Dr. what you want and what to prescribe?

Be careful of any Dr. who would do this....you may find them shut down by the DEA one day and then your name/records are tied to him...

It's actually surprising that he put you on both Oxycontin and Fentanyl...Most Dr.s stick with only one long acting medication and then add in a short acting one for breakthrough pain...

Same with your insurance....you are very lucky that they are ok with paying for both...Again...you just need to be careful...People have found themselves being on medicine that no other Dr. would prescribe if you ever need to change..

Wait for your doctor appointment and let your doctor figure out the conversion. That's his (or her) job.  I know as patients we like to have some kind of control over what we put into our bodies, but when you're talking about opiate therapy it's a bad idea to make med changes without involving our doctors.
