No, there has to be some condition, cause, not mere personal opinion, but PROFESSION opinion, involved in what is filled and what isn't. I'd think that any pharmacist who took to referring to random drugs as offensive due to "religious" reasons who could not provide substantiation as to the religion and principles involved in those specific drugs, would be discharged for incompetence (or similar), if not lose a license.
There is recognized moral difficulty and offense associated with birth control and/or abortion-inducing medications. They are readily identifiable to most reasonably intelligent people as being capable of terminating human life, or, as some claim, "removing tissue".
I believe there'd be a strange circumstance if a Scientologist was licensed as a Pharmacist (or would they ever pursue that profession, I don't know, and doubt it) and then refused all medication orders based upon thier "religious" objections, in which I just don't know how that would be handled other than they'd face an argument with the licensing board, certainly their employer.
However, that's not the case here. This Pharmacist only objected to birth-affecting, life-terminating medications and it's not at all the same thing as if she'd just randomly named a drug or drugs with no recognition of controversy.
