The mifepristone pill, often used with misoprostol, is used to end a pregnancy through ten weeks gestation (70 days or less since the first day of the last menstrual period).
How Mifepristone Works
Mifepristone functions by blocking progesterone, a hormone vital for the continuation of a pregnancy.
- Progesterone Blockage: Mifepristone's primary action is to block the effects of progesterone.
- Pregnancy Termination: By blocking progesterone, the lining of the uterus thins, preventing the pregnancy from continuing.
- Misoprostol Combination: It is typically followed by misoprostol, which causes the uterus to contract and expel the pregnancy.
