My Doctor Recently Changed My Medication To 25mcg Of Fentanyl

My doctor recently changed my medication to 25mcg of fentanyl and I'm not happy with the decision how much medicine is being released per hr with this dose. He said this is a very strong narcotic but if im fine with the 10mg Percocet shouldn't I have a say about this . He says that the Percocet is a short term med and the other is a long term med how true is this
