How does the abortion pill work? 

The first dose of the abortion pill (Mifepristone) blocks the natural hormone progesterone. Progesterone is necessary for the growth and development of your baby and the placenta. Without progesterone, the placenta will separate from the uterus. If you take the second dose of the abortion pill (Misoprostol), this will cause contractions to empty the contents of the uterus. It is possible to reverse the abortion process following the first pill and before you take the second pill.

The Abortion Pill Process

The 1st Pill – Mifepristone

  • A doctor will give a woman considering chemical abortion a physical exam to determine if she is eligible for this type of chemical abortion procedure. Not all women are eligible.
  • She may be given antibiotics to prevent infection.
  • She will be given an oral dose of mifepristone during her first office visit.

The 2nd Pill – Misoprostol

  • Misoprostol tablets are taken orally or inserted vaginally about 6 to 48 hours after taking the mifepristone. The tablets cause contractions and expel the remains of the baby. This process may take a few hours or as long as a few days.
  • The woman will need to be examined by her doctor two weeks later to ensure the abortion was complete and to check for complications.

The procedure is unsuccessful approximately 5-10% of the time with the potential of requiring an additional surgical abortion procedure to complete the termination.

All women considering chemical abortion should be informed about the side effects and risks of mifepristone and misoprostol.
