Plan B, an emergency contraception that should be taken within 72 hours of unprotected sex to prevent pregnancy, will be available over-the-counter to women age 15 and up.
The Tuesday announcement by the Food and Drug Administration (FDA) might sound like a win for women's rights organizations but it also means that girls and women who want the pill will have to prove they meet the minimum age requirement.
And that can be a problem for some.
People who request the pill will have to show a driver's license, passport or birth certificate. Most states don't allow people to apply for licenses until they are 16. Even then, fewer than one-third of all 16-year-olds have a license.
