Okay so I had two back surgeries, the last one being May 22 of this year. Since then I have tried just about every single pain medicine there is out there including break through meds and long lasting(controlled release) meds. About six weeks ago my doctor thought it would be a good idea to switch me to the Fentanyl patch. First, like in most cases, he started me on the 25mcg patch. It helped alot compared to oxy contin and MS contin, but it seemed like after a week or so my body got used to it and it began to loose its potency after the second day. My doc switched me to 37mcg an hour and the same thing happened. Now I am leveled off at 50 mcg an hour which has been working pretty good. The only problem with these patches that I have expirienced was from the Mallinkrodt brand. Before taking this I had used the Watson and Durugesic gel style, and the Sandoz and Mylan carrier styles with no problems at all as far as side effects. When I was on the Malli's I got a horrible break out of huge zit (almost sist like) bumps on my back. Along with that I had headaches and fatigue feeling starting when I woke up for a few hours and some days, all day long. It was horrible, and the worst part about it was they didn't even help me with my pain! They are alot different than the other carrier style patches in appearance too, they are a lot thicker and cloudier in color, the only good thing I can say about them is they stuck better than some brands. Has anyone out there had similar experiences with this nasty brand of patch??
