Common Questions and Answers about Fentanyl vs meperidine

There are a couple differences between medications that are worth noting; meperidine or Demerol should be avoided in the doses you are describing, as the primary breakdown product, normeperidine, is neurotoxic and causes seizures; Codeine is not a good choice at these doses as it just does not have that much potency; Morphine does tend to cause more stomach cramping and nausea, and is subject to high 'first pass metabolism' that makes oral dosing difficult; Any opiate at these dos
Fentanyl is a stonger form of an opioid. Opiate and opioid mean the same thing: Opiate is an adjective while opioid is a noun. Percocet is an opioid as is fentanyl. They are synthetic which means they are man made and not derived from a plant.
Good job on getting off the Percocet!
Although methadone and fentanyl are also heavily protein bound and as such require reduced dosing in patients with cirrhosis, the metabolism of these agents does not yield toxic metabolites, and hence they, along with hydromorphone, may be better tolerated37,38 (Table 2)."
".....Hydromorphone and fentanyl appear to be the least affected by renal dysfunction, and fentanyl has less hemodynamic disturbance (due to lack of histamine release associated with other opioids).
Hi, I have been on fentanyl 75mcg and oxycodone 5-10 mg/day for the last year - ischemia and trigeminal neuralgia.
I really want to get off these meds b/c of addiction issues etc. My doctor maintains that I have probably developed a tolerance to these meds. (tolerance vs meds - same thing??). In any event I stopped the oxycodone 10 days ago and my doc tapered the fentanyl patches to 40mcg for 1 month then 12.75mcg for the next month. Also rx'ed clondine and klonopin for anxiety.
I am hospitalized a couple times a year and years back I was given 1st given dilaudid then morphine and both made it much worse. After many hours of extreme pain I was given meperidine (Demerol) and it worked very well. After I was stabilized I was given a Fentanyl patch(25 mcg/hr) which also worked. So there are alternatives to what you were given that made it worse.
This just does not make sense that u had to lie that u were an addict and then only have options like sub. Be careful of the fentanyl patch even though it is excellent for pain relief. Fentanyl is 100 times stronger than morphine and 50 times stronger than heroin. Do the research. If you ever had to w/d from fent, suboxone for sure would not cover that. I tried the patch and let me tell you, I had noooo pain at all. I got off it just as quick when I did more research.
You will most likely be on pain meds for the rest of your life so I would suggest that you and your Doctor find the best one for you. I use the Fentanyl Patch along with Morphine for breakthrough. Ask the Doctor about the possibility of using Fentanyl. I find it easier on my system and I don't feel "high" all the time.
Well, I wish I had more advise for you.
I was on morphine SR 60mg twice a day for years and my doctor switched me to fentanyl 25 patch. I ended up with severe withdrawal and went back to the morphine for a week until my next appt where he put me on the 50 patch. Still I am going through withdrawals. My pharmacist says I can't be but I know 100% that's what is happening. Anyone else deal with this?
ve been taking opiates for over 2 years and your doctor obviously sees you as opiate tolerant and capable of handling the fentanyl or he woud not have given them to you so I think you can relax about the overdose concern.
As for addiction, it is a danger with ANY opiate. Althought the patch you have is on the lower end of dosage, it IS a strong opiate. Do you believe yourself to be an addict?? Or merely dependent?? Do you plan to stay on these forever?? Or are you wanting to stop??
t bother with Pain management because all they will give us an injection of Fentanyl! No thank you. I stick to my Tylenol #3 with Codeine. I use the Teva brand the rest of the pharmaceutical brands make me nauseous. But Oxycodone w/apap 5/325 is good also again only the Mallinckrodt brand. Don't take just any brand do your research.
I prefer the fentanyl patch because it is all pain med -- fentanyl is a pure opiate agonist, like morphine, where as Butrans depends on a medication that is part agonist / part partial agonist.
But either patch should be worn only by those who are opiate tolerant. Even the circular provided with the Duragesic patch warns against using the patch in those who aren't used to opiate analgesics.
Have you tried Oxycontin?
That is 150 mg of Oxycontin less than what you were taking through Fentanyl vs. 90 mg of Oxycontin more than you were taking. It now makes perfect sense to me why you are in so much pain on the Fentanyl. Converting 360 mg of Oxycontin to Fentanyl results in 150 mcg/hr...this is conservative. Converting Fentanyl to equal 360 mg of Oxycontin with the opioid calculator results in 300 mcg/hr.
I was wondering what could happen if I mix meperidine promethazine with propoxyphene acetaminophen. I'm asking because a friend of mine wants to do it, but I don't know what will happen to him. So please help me out.
