I was extremely allergic to the adhesive on the patch. I wish I hadn’t been allergic because it completely done away with my chronic pain without any other side effects. Plus it’s not addictive. My insurance would not approve another form of it or I would still be taking it. My doctors put me on Fentanyl Transdermal Patch around 10 years ago. I hate the way it makes me feel. Now the insurance company and the laws governing pain medications are constantly trying to have my doctor take me off of it. It helps my pain but I’m never NOT in pain. I have tapered down the last few years from 100mcg per hour (highest dosage) to now I’m on 25mcg per hour and they want me completely off it. My opinion is that the insurance companies and the government officials need to stay out of it and allow the medical professionals alone to do the job they were trained to do.
