Plan B, the emergency contraceptive pill that went over-the-counter in 2011, sells for around $50. That is the only example we have of a similar drug on the shelf. Depending on the pill, the out of pocket cost right now can range from $20 to $100 per pill pack, explains Sally Rafie, PharmD. Of course, birth control choices aren’t just driven by costs — but also by side effects and other health concerns, such as acne, polycystic ovary syndrome, endometriosis, and more.
