FWIW, Catholicism has adopted the "doctrine of double effect" where oral contraception is concerned. If a woman's "primary" reason for taking them is dysmenorrhea or something similar (and let's face it: doctors have been writing "dysmenorrhea" on charts for decades to get around insurance issues), it is perfectly acceptable for her to take them. And I don't know a single priest who would suggest a pharmacist investigate/interrogate the reasons a woman was on them. Not to say they don't exist, or that Catholic pharmacists might not know said doctrine is outside the realm of possibility.

(Why this doctrine doesn't apply to a married couple using condoms when one partner is HIV+, an interpretation specifically rejected by Benedict's Vatican remains an infuriating puzzle.)
