I was on both of those medications, and
I went through quite a few other doses and
medication types before we started fentanyl
even then...we started a low dose patch and worked up from there.
If I were you, I would get another opinion, or go talk to the doctor...something. There are many other meds available at much lower doses. Fentanyl is approx 88 times stronger than morphine. I am just bewildered as to why he would start with 50mcg, maybe it was a mistake.
