Yeah I dont think you were on a fentanyl patch. They are 12.5mg, 25mg, 50mg, 75mg, and 100mg.
I was put on the patch from a PM doc after being sent straight to the ER from the MRI place and I had serious issues on the 25 mg patch because I had not been on ANY opiates at all. No percs, no nothing for a bit. The severe headache and nausea and it was awful. I finally took it off after I realized that I had NO BUSINESS being on this patch and the doctor OVER REACTED BADLY......... and now I have been doing ok. Had surgery and he has me off pain meds to see how my hips reacts to the back surgery which is still in a lot of pain but I am trying.
I would seriously ask what he had you on because I do not think it was either the pain patches listed in this thread. There is no such dose for those.
Don't sweat petty things....or pet sweaty things
