Yes, A doctor and pharmacist share liability 50/50 on a prescription. Any pharmacist can refuse to fill any prescription if in their professional judgement the prescription is not appropriate for therapy, or as someone else said for religious reasons, although in states that allow that, there has to be another pharmacy that the patient can potentially fill at (does not mean that the pharmacist there has to fill it either, so if all pharmacists are refusing to fill, then that's that). Pharmacists know less about diagnosis and non-medication therapy, but way more about medication than doctors. Making these decisions is the entire point of our license.
