The U.S. Food and Drug Administration (FDA) finally changed the labeling of the emergency contraceptive Plan B One-Step, removing an inaccurate statement that the medication may function by blocking a fertilized egg from implanting in the womb.

The inaccurate language resulted from a compromise with anti-abortion science advisers to the FDA when the medication was approved for over-the-counter-sales in 2006. Anti-abortion advocates, who claim that “life” begins at the moment of fertilization, have used the FDA label to justify their belief that emergency contraception causes abortion.
