Chapter 10 – Pregnancy Options

Medical abortion

There are different protocols for medical abortion throughout the world, but in Australia the accepted regimen is a two-stage process:

A single tablet of mifepristone 200mg is first taken orally. This is a progesterone receptor antagonist and blocks progesterone needed to maintain the pregnancy. This is followed by self-administration of 4 x 200mcg misoprostol tablets taken 36-48 hours later. Misoprostol is a synthetic analogue of prostaglandin E1 which causes uterine contractions to expel the contents of the uterus.

For more information about the characteristics of surgical abortion, see Table 10.1.
