Deb,
I used the Fentanyl patch for about a year and a half with pain relief that was pretty good. Fentanyl is potent medicine and you will be started on a low dose for sure. In my experience dizziness was a major issue. I also had some problems with skin rashes. (I don't recall it causing the big-D, you are more likely to get constipated.

) Over all, I would use it again with no hesitation if needed.
