question: my father has been taking chemo and radiation therapy for lung cancer. he is 75 yrs old and has stage IIA cancer he is stopped taking treatment due to hoapitalization for confusion  but my question is that he is currently being administered (3) 100mcg fentanyl patches at the same time and new ones are put on daily. is it unusual for someone to be given such a large dos of fentanyl  along with 30mg of morphine every 2 hrs
