I have been on the fentanyl patch 12 mcg/hr for a little over a year now. I have a new pain management doctor that just increased the patch to 25 mcg/hr. Just curious if anyone had any new side effects or significant changes after increasing the dosage. (Doesn't have to be specifically from 12 to 25, it could be from 50 to 75, or 75 to 100, etc)
