I did not read all the posts here but I did see that someone mentioned it is ok to to put a tagaderm cover over a fentanyl patch and you will be ok to take a hot bath. I'm pretty sure that if you read the paperwork that comes with the patches that you will see it says never take a hot shower, use a blow dryer, use a sauna, use a hot tub, etc. because the tagaderm will make sure the patch does not get wet and have to be thrown away but since fentanyl patches get delivered by heat, you will be essentially be over dosing when you get the patches hot. The patches are suppose to last 72hrs but if you get them hot even for minutes you can use up all the fentanyl in under 24 hours which means you will probably go thru withdrawal too. Not fun.

If you have been on fentanyl patches for years and are tired of dealing with this problem ( because we can't stop our body from sweating and overheating when you have CRPS), then consider a pain pump.

All I'm saying is be careful please
