On December 7, 2011, Health and Human Services Secretary Kathleen Sebelius overruled the US Food and Drug Administration's (FDA’s) decision that levonorgestrel emergency contraception (sold under the brand name Plan B One-Step) was safe and effective for all women of childbearing potential, regardless of their age, and should be approved for sale as a nonprescription drug. Plan B One-Step is a single-dose 1.5-mg tablet of levonorgestrel that should be taken as soon as possible and within 72 hours after an episode of unprotected intercourse.
