Plan B: Emergency Contraceptive Pill
MetadataShow full item record
Plan B is a progestin-only emergency contraceptive pill (ECP) that can be taken within seventy-two hours of unprotected sex in order to prevent an unwanted pregnancy. Plan B was created in response to the United States Food and Drug Administration's (US FDA) 1997 request for new drug applications (NDAs) for a dedicated ECP product, and was approved for sales in the US in 1999. Duramed, a subsidiary of Barr Pharmaceuticals, manufactures Plan B for The Women's Capital Corporation (WCC), which owns the patent for Plan B. This technology is important in part because it expands women's reproductive rights by giving them greater control over their fertility. The mechanism of action of Plan B also raises questions about the moral status of the zygote.
