Drug makers are facing growing pressure to sell contraception without a prescription. And this weekend, the nation’s largest physicians group could join in the chorus calling to expand access to birth control.

At the American Medical Association’s annual meeting in Chicago, delegates will vote on a resolution to encourage contraceptive makers to submit applications to the Food and Drug Administration to switch the status of their pills from prescription to over the counter. If it passes, the new policy would be directed more squarely at drug makers than the AMA’s current policy, which focuses on the FDA’s role.
