chronic pain
"Spinal fusion pain is often severe while usually moderate. My doctor prescribed 100 mcgs for the usual 72 hrs., but after about 6 weeks of use I entered into painful, often agonizing withdrawal symptoms during the night and had to replace my lost, misplaced patch. Pain relief is satisfactory, but I find the Transdermal system's adhesion properties unreliable at best. 

Tegaderm adhesive film is essential for extra security while holding the patch to the skin. Unfortunately, my Fentanyl patches are vulnerable to moisture and prematurely weaken, even with the added film."
