Fentanyl onset of action
Common Questions and Answers about Fentanyl onset of action

At our hospital we have a Fentanyl protocol, and this might work quite nicely for you. Fentanyl has a rapid onset of action, and wears off quickly. If you were my patient, and likely to deliver quickly again, I would strongly consider using this medication for you. By the way, it is also safe -- safer than Demerol actually.
Good luck!
Short-acting medications like Percocet, increase the build-up tolerance due to how the immediate release action of the pill works on the body. Extended release (long-acting) medications slow the build-up of tolerance as the medication is released slowly and steadily over an extended period of time from 8-12 hours to up to 7 days of action. The Percocet you take now would become a breakthrough pain medication that you take in between doses of the long-acting medication only as needed.
m interested in hearing from anybody who has had similar symptoms, or a similar course of action before getting a diagnosis. I have never really heard of tinnitis or vertigo being symptoms of MS, and those are the main reasons I even started pursuing medical help to begin with. The doctors have ruled out some explanations (like the acoustic neuroma), but there are still other possibilities on the table (Meniere's disease, or even high blood pressure for example).
It kind of sounds like a form of Action tremors, but I have to agree with mkh9.
Wow! You take 300 mcg of Fentanyl every 3 days? That's a seriously high dose. Like mary said, you will develop a tolerance to opiates, which means you would keep requiring a higher and higher dose to reach the same level of effectiveness.
You posted in the addiction forum. Do you abuse your meds? If not, then I agree that this would be more suitable for the pain management forum.
Are you getting your meds through a pain management doctor?
The onset of action ranges from 45 minutes - 1 ½ hours, and the duration of action is six hours. Diazepam carries a bi-phasic half-life of 20-50 hours (for Diazepam), and 30-200 hours (for Desmethyldiazepam). Valium is indicated for the long-term management of generalized anxiety and tension-anxiety. Tolerance will not develop to the anxiolytic property of Diazepam, although tolerance will develop to the sedative/hypnotic property.
A partial µ-opioid receptor agonist, its mixed agonist/antagonist activity affords it a lower risk of dependence and abuse than full µ agonists like morphine. Meptazinol exhibits not only a short onset of action, but also a shorter duration of action relative to other opioids such as morphine, pentazocine, or buprenorphine.
What is the onset of action after taking a dose of the immunoglobulin.
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. 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.

Initially when I saw that you were on 175 mcg/hr of fentanyl I was shocked as that it is a really high dosage of fentanyl! So you are getting almost twice as much oxycodone through Fentanyl TD. I'm very surprised that your doctor wants to keep upping the dosage. I don't think that is the right approach. Have you considered getting a second opinion from another pain management doctor?
My 29 y/o daughter occasionlly experisences sudden moderate to severe upper back pine along the spine from neck halfway to waist. Shortly following onset of this pain vomiting starts and continues on and off for hours. She had positive ANA but further eval for autoimmune illnesse proved negative.
Where should she be followed for these symptoms?
In defense of my GP I am extremely sensitive to a whole bunch of meds and Fentanyl was a last resort. I can not take any form of NSAID's and any neuropathic treatment such as anticonvulsant or antidepressant sedated me to such an extreme it was intolerable even at paediatric doses. My issue is with the drug company who stated that stopping the patches could make me unwell?
