In December 2003, the FDA recommended making the pill, also known as “morning-after” emergency birth control pill, available for customers over the counter. The pill should be taken within 72 hours after an unprotected sex with taking a second dose in 12 hours. The effects of this birth control pill are based on the activities of a high dose of the hormone progestin (some types of morning after pills contain levonorgestrel), which help to avoid fertilization by not allowing the overies release egg or preventing sperm from reaching the egg. Morning after pills have been known among medical experts for the last two decades. But for many years, a lot of women in the United States remained unaware and misinformed about their use.
