I have read so many post about what to use to help keep the fentanyl patch on and was surprised nobody has heard of Tegaderm. They are a clear patch tht is used to help protect wounds. Its a clear patch and peels off technically like our patches. Essentially a second skin. Try'em! Make sure to try and get the store brand which is $3 cheaper in my neck of the woods (NC). Just go to your local drug store and ask where the tegaderms are. I hv to use two but the sell larger ones which I plan to try and cut in half next go round. Good luck!
