From Wikipedia, "Fentanyl (also known as fentanil) is a potent, synthetic opioid pain medication with a rapid onset and short duration of action. It is a potent agonist at the μ-opioid receptors. Fentanyl is 50 to 100 times more potent than morphine.
I can't tell the effect from the fentanyl but it must work fine for me. Yes, it is administered by IV.
