Abortion can be induced for medical reasons or because of an elective decision to end the pregnancy. Procedures for inducing abortion include vacuum suction (the most common, used in the early stages of pregnancy), dilatation and evacuation (D and E), induction (injection of abortifacients such as prostaglandins into the uterus), and hysterotomy (a surgical procedure similar to a cesarean section, used later in pregnancy, especially when the woman's life is in danger). The "abortion pill," the drug RU-486 (mifepristone), was approved by the Food and Drug Administration in the United States in 2000. It is used within the first seven weeks of pregnancy. A second drug is taken two days later to start uterine contractions and complete the abortion. The drugs methotrexate and misoprostol have also been used experimentally to end early pregnancies.
