Fentanyl
"I have been using the Fentanyl patch for about 10 days now (50mcg), and it works very well. I also use Norco 10/325 for breakthrough pain. I was previously on MS-Contin 45mg/3 x per day with Norco for breakthrough pain, and it didn't work half as good as the patch. I have adhesive arachnoiditis, and the Fentanyl patch has been the only medicine that allows me to walk around the house.  I was bedridden otherwise.  The only issue I have with it is the medicine doesn't seem to last the whole 72 hrs, only about 64 hrs.  I place the patch on the side of my abdomen, where movement is minimal, and it seems to stay in place better than on my arm or anywhere else."
