I started a pain management plan & we were going to do 240 percocet 7.5s a month then he left for a minute & came back & said he decided to do fentanyl 25mcg/hr he said that is equivelent to taking 8 percocet 7.5 a day I need to know if the patch is that strong or if I need to talk to him so we can get it right because I am in alot of pain every day
