At our institution we use 25 mcg for term inductions (with a foley bulb is the cervix is dilated enough). The one caveat is that its prefered over Cervidil because of price, but can lead to a stat cesarean delivery from hyperstim.
For early pregnancy induction, it depends on the trimester and the scenario, and the dosing is anywhere between 400 to 800 mcg (provider dependent).
Hope this helps ya!
