Mifepristone is a medication primarily used to terminate early pregnancies. It works by blocking the hormone progesterone, which is essential for maintaining a pregnancy. When taken in combination with another medication called misoprostol, it can effectively induce a miscarriage within the first ten weeks of pregnancy. In addition to its use in abortion, mifepristone is also prescribed for managing certain medical conditions, such as Cushing's syndrome and uterine fibroids. It is important for patients to consult healthcare professionals for guidance and support when considering its use.
