Yes, it is marketed under the trade name name Actiq, and is also been available as a generic since 2006.

24 to 36 hours tops. Fentanyl is the fastest acting opioid on the market due to it's mode of action (mouth). It's fast in and fast out.

That is not a fully explained response. Oral Fentanyl, such as Actiq and Fentora only have a half-life of 4 to 6 hours. The patches can take up to approximately 24 to 30 hours once you remove them. Fentanyl metabolizes very quickly.

Depending what type of for you take Fentanyl in, it can vary. I'm on Actiq 1600 mcg's, it has a half life of 7 hours. Multiply 7 hours by 7 half lives you come up with 49 hours. So, since you last dose of Actiq, it would take 49 hours to clear your system. Give or take a few, depends on your metabolism. If you have access to read this. just Google your questions, that's where I get my info.

Yes. But you will have to consult your pain management specialist first, and perhaps do this in a hospital where you can be intubated if your airway becomes unstable.

For those unaware, Fentora is used in cancer patients.

All 3 meds are Fentanyl.
