A 2006 FDA ruling that allowed emergency contraceptives to be sold to adults without a prescription effectively improved access to the drug that prevents pregnancies by delaying the release of an egg from the ovaries, according to a survey of pharmacies in three major U.S. cities. Because the drug is most effective within 24 hours after unprotected sex, lead researcher Rebekah E. Gee of the University of Pennsylvania School of Medicine says that over-the-counter access should be extended to teens, as well. "There's no evidence that [it] leads to more intercourse or riskier behavior," she said. "The data definitely show that that's not true."
