I been on these Fentanyl patches 10 yrs. now I was on Watson & Mylan well all of a sudden new companies send them and I want to know if anyone else is having problems with their pain tolerances ? The old brands of both worked fine for me but now I been getting Mylan and they don't seem to be holding my pain! Is there another brand that works better? and has anyone else noticed the difference since the change in companies with these two brands? I thought I was having more pain but than someone else said this to me so I know it's the patch!
