While the fate of mifepristone, also known as the abortion pill, plays out in US courts, health-care providers have another drug they can continue to use to offer medication abortion.

Misoprostol is primarily an ulcer medication, but it’s used in conjunction with mifepristone in 98% of all reported medication abortions in the US, according to the Guttmacher Institute, a research organization that backs reproductive rights. The combination is “the gold standard for medication abortion in the US and elsewhere,” said Alice Mark, interim medical advisor for the National Abortion Federation.
