The president of one reproductive nonprofit thinks freeing the pill from the pharmacy would help it live up to its potential. The pill already meets the FDA's over-the-counter criteria because you don't need a doctor's expertise to tell you you need it, there's no risk of addiction, and the side effects are less dangerous than other over-the-counter drugs. Just like they do with other over-the-counter drugs, women could screen themselves for any preexisting conditions that put them at higher risk of side effects. When you think about it, if the morning-after-pill is available over the counter, why not the birth control pill?
Well here are some reasons. It could drive up the price, making it less accessible to low-income women. And I'd imagine that it might give women less incentive to visit their gynecologists regularly. For example, once your one-year prescription expires, a doctor often requires a check-up, which can include cervical cancer and STI screenings, before it's renewed. And, of course, there will be some people who oppose greater access for moral or religious reasons.
