The Correct Answer is C

Mifepristone blocks the action of progesterone, which is needed to sustain a pregnancy. This results in:

  • Changes in the uterine lining and detachment of the pregnancy
  • Softening and opening of the cervix
  • Increased uterine sensitivity to prostaglandin.
Mifepristone is used in combination with another medication - a prostaglandin analogue called misoprostol. Misoprostol causes the uterus to contract and helps the pregnancy tissue to pass.

It is important to note:

  • Medical abortion with mifepristone/misoprostol requires at least two visits to a doctor's office or clinic.
  • Approximately two-thirds of women will have a complete medical abortion within 4 hours of using the misoprostol.
  • Approximately 90% of women will have a complete medical abortion within 24 hours of using the misoprostol.
  • Complete abortion generally occurs more quickly when misoprostol is used vaginally rather than orally.
