Accutane Process? in Prescription acne medications Posted November 13, 2014 Ah, I see your dilemma. Because usually doctors call it in, if you call it in they can't fill the prescription because some random guy called them and told them to. I would just call them, tell them what's up and they'll either tell you to bring it in, or call back your doctor. In terms of how long it takes to get the meds, it varies by pharmacy, but accutane is pretty common so it shouldn't take too long to get, at least as I remember it.
