From what are hear
Fentanyl (a synthetic heroin-like drug, metric unit used to measure it's dosage is "Micrograms" "Mcg") is an excellent med for break-through break. It usually comes in patch that delivers the drug slowly or it also comes in the form of Actiq lollipops, which can sucked on slowly and the drug will absorbed transmucusolly or sublingually. But I'm not sure whether you should take it since you already are on Morphine 60mg twice a day. Fentanyl is short-acting, that's why it used for breakthrough pain. But it can also be used as the primary med for intractable pain, that's how the patches are utilised. For break-through pain, the lollipops are utilized for people, who are already on narcotics for pain, but on occasion, the pain breaks through the narcotic pain-killer, and pain is "FELT!!" from the user. An exceptionally strong and short-acting analogue of fentanyl is "Sufentanil" or "sufenta", it fifteen times stronger then Fentanyl, and Fentanyl is 80 times stronger then Morphine. Another Fentanyl analog, which is exceptionally strong is "Alfentanil" or "Alfenta". Do a Metacrawler (my favorite search engine) search, find the most informative site that explains Fentanyl and how it is used, print it out and read through it, highlight those features that explain it's used for "break-through pain", and bring it to your doc on you next visit, if he's not familiar with the med, then make sure you also bring along with the varying dosages it comes in, as well as how the doctor should prescribe it, like how often one can use the lollipop and it's varying methods of delivery. Find a site that tells doctors on how to prescribe it and print it out. I'm happy you found a doc that is willing and "open-minded" with treating your pain. Don't mess it up, docs like that are hard to find. Good Luck Friend.
