How does the abortion pill work?

Medical abortion is accomplished by taking two types of pills: mifepristone and misoprostol. This is the most common treatment for people who are 11 weeks pregnant or less. Mifepristone is taken first to block a specific hormone that allows a pregnancy to continue developing. Misoprostol is taken second to induce bleeding from the vagina and cramping, which helps the pregnancy pass from your body.
