Buprenorphine
"I'm on Butrans 10mg, plus, 15mg morphine 4 times daily for breakthrough pain for 6 months. I've heard people say the patch decreases in effectiveness by day 5. Haven't had this problem. Try not to take too hot a bath/shower. The patch has really helped to keep my pain level at a constant. And used with the morphine, let's me function fairly well on most days. If you have problems with it not sticking, srub your skin well with hot water [no lotion], and dry, then, gently put on patch [don't stretch it], it will stick. Don't get too hot outside, it can make you sick. I do outside activities in cooler parts of the day! Good luck!"
