I've been on the Fentanyl 25mcg patch almost 2 months. The last few patches I've left on one shoulder for 5 days while I always place a new patch on the opposite shoulder every 3 days. I place a heating pad on the"older" patch days 4 & 5. Is this helping my pain level at all, or is it all in my head??

It says in the fentanyl insert that after you take off patch, it takes 17 hrs for the medicine to drop to 50%. Which means, for example, you have a 50mcg patch on, take it off and it gradually loses its potency. So if u put on a new one and leave the old one on, you are essentially getting extra medicine for up to 34 hrs. If it takes 17 hrs to reduce by 50%, then 17 x 2- 34hrs. Lord have mercy I hope this makes sense! LoL... I think im losing myself! Good luck and Merry Christmas!
