If a dot of fentanyl can kill you, how do we use it in medicine, and how do people get addicted?

Question

I’ve always heard that a singular dot of fentanyl can kill you. Yet we use it medically, for pain relief. And many people are addicted to it but stay alive while using. Is there like a different method of using it? How do people use it and not die?

Answer 1

Had to get a bone marrow biopsy from my hip. Was given a Benadryl and .125 micrograms of fentanyl. The only part of the procedure that I wasn’t asleep for was when I felt someone pushing me down into the table to drill the hole, and I didn’t feel any pain just felt like someone was pushing down in my hip. Walked out of the procedure and was normal within an hour or so and it was the Benadryl that was messing me up. So yeah fentanyl is great stuff when used in small doses in a hospital setting.
