As the FDA prepares to announce whether the contraceptive can be sold directly from drug store shelves, here’s a timeline of its development and accessibility in the United States.
1999 In 1999, the FDA approved use of levonorgestrel, an emergency contraceptive that would be sold under the brand name Plan B. It consisted of two tablets, the first to be taken within 72 hours of unprotected sex and the second to be taken 12 hours later. Around the time of its approval, it was reported that a study sponsored by the World Health Organization showed Plan B caused less nausea and vomiting than other so-called "morning-after" contraceptives. /AP Buy Photo
