Fentanyl vs morphine potency

Common Questions and Answers about Fentanyl vs morphine potency


688620 tn?1227381884 Fentanyl is one of the most powerful opioid analgesics with a potency approximately 81 times that of morphine. I note that you posted this nine hours ago. Your patch should now be in your system. It may take a few more hours to peak and last for up to 72 hours. The strength is higher than you former extended release morphine dose. There is some very good information on the Internet concerning Fentanyl Patches. There have been several recalls of the patch that contains the gel.
Avatar n tn Incidentally, she reminded me that she was on the patch for a while but thought it was morphine instead of Fentanyl. I don't remember as she's been on so many meds that I can't keep track of them. She liked the IV machine with the push button the best. I watched her nurse change the morphine casette one day and was amazed at the size of the thing! It looked like it might hold four oz. or so. Yeah, I hope you never have to be in the pain my poor wife has endured for six years.
Avatar n tn I think there is a misconception out there that 50 mg of painkiller A is equivalent to 50 mg of painkiller B in terms of potency, half-life, withdrawal, etc. This is just not true. The quantity matters when making comparisons, as does the method of administration (oral vs injected vs snorted vs smoked). Just google "equianalgesic table" and you will see what I mean.
Avatar f tn So if you remember I converted your total daily dose of Fentanyl to Oxycontin and it came out to be 210 mg of 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.
Avatar f tn For example, the A118G genetic variant of the mu opioid receptor, which results in a change in amino acids from asparagine to aspartate at position 40, has been studied in both pain (Hirota et al 2003, Lotsch et al 2002, Lotsch et al 2002, Ross et al 2005) and addiction (Bergen et al 1997, Bond et al 1998, Li et al 2000, Sander et al 1998, Town et al 1999), with conflicting reports on its relationship to morphine potency or its association with risk of substance abuse.
1866508 tn?1333988213 There are also other long acting meds beside Oxycontin that you could look into such as Oxymorphone (Opana), Hydromorphone (Dilaudid), and Fentanyl which all have a potency that is greater than morphine. My appointment is Jan 3rd, I will let you know how it goes.

Avatar n tn ppl who get off sub and try to go back to using will not feel anything at all from heroin, oxycontin, fentanyl, morphine, vicodin, etc for at elast a week. suboxone last right around 2 days-48hrs, so for it to leave your system, especially if tis been taken for long periods, it will take msot likely alot longer than a week to even feel miniscule effects from other opiates of abuse. methadone si the onyl drug out there that can voerride suboxone in giving an effect.
Avatar f tn Dear Fabulously Helpful Pain Management Group, I had my doctor's visit and she up my dosage of 30 mg. Morphine Sulfate from twice per day to thrice per day. I also still need to take the four (4) 10/325 percocet as well, but so far so good. This forum has helped me so very much before and I thank you, and then thank you again! Of course, I have been reading some of these posts just today and I have to questions that only you as a group can answer for me.
Avatar n tn I was taking for two wks percocet (oxycocone-acetaminophen 5-325) 2 every 3 hours(5 doses daily) vs opana ER 5mg 1dose 2tms dly which is generally stronger? And how do most people out there like opana?
Avatar m tn Hi, As a sub user since 6-24-08 I have felt the best I ever have in 28 years of addication. Two really important points OC stated: People on hydros, I agree, sub is not the answer. Taper. Short term addication, I don't think sub is right. Really young kids 19's & even 20's to me.(unless there is a true need) For me and my friends that are on the sub program we all have long history of opiate abuse. heroin, oc's & morphine both in the 400mg a day range.
