Fentanyl Patches

From time to time the FDA recalls misc brands and strengths of the fentanyl patch.  My question doesn't ditrectly relate to recall but I normally get the Duragesic brand name patches or generic Sandoz brand.  These patches had a gel inside and was secreated through the adhevise into the skin. The patches now no longer are made with the gel inside. They are made like the Mylan patches . The first week of the change I hurt so much worse... almost like I did have a patch on at all.  My doctor said instead of taking only hours to level in your system; there take atleast a week. I am on the 100mcg patches which is the highest dose my doctor will prescribe. And my breakthrough medicine is Oxycodone 15mg IR tablets and I take two every 4-6 hours. All my doctor says is it will level itself out... Meanwhile I am still waiting... From what I understand this is permanent change made by the FDA and drug manufacturing companies to discourge abuse and/or overdose... Has anyone heard anything about this? Any details, info or insight? Is there another brand that didn't change?
