The abortion pill (Mifepristone) works by blocking the hormone progesterone. Progesterone is required for a pregnancy to continue. When progesterone is blocked, the connection with the uterus is lost, thus causing the death of the embryo.
The FDA requires a single medical office visit. If the abortion provider determines that the abortion pill is right for you, he/she will give you the Mifepristone to take orally, which will cause the death of the baby over the next few days.
Next, a day or two later, Misoprostol tablets are taken at home or at the abortion provider’s office. These tablets are placed inside the cheeks and given time to absorb. This drug causes the uterus to contract, and the baby is expelled. Cramping may be severe, and vaginal bleeding usually lasts for one to two weeks.
