There are two abortion pills - Mifepristone (RU-486, Mifegynae, or Mifeprex) and Misoprostol (Cytotec, Cytotecal). They are usually supplied in a single combi-pack such as Termipil Kit or Killpreg Kit. Mifepristone is taken first, followed by Misoprostol the next day.
Mifepristone is a medication that blocks the natural hormone progesterone. It softens the cervix and prepares the uterus for an abortion. The usual dose is 200mg when used in the first 12 weeks of pregnancy. Mifepristone can be either swallowed with water or kept under the tongue for thirty minutes. It should be followed 24-48 hours later by Misoprostol
Misoprostol is a medication that causes contractions of the uterus and ejects the pregnancy. The contractions are experienced as strong cramps accompanied by bleeding, similar to a heavy menstruation. Misoprostol is taken at a dose of 800mcg (usually four tablets of 200mcg). Misoprostol tablets are usually kept under the tongue for thirty minutes, and the remains are then spat out. If cramps and bleeding do not start within three hours after taking Misoprostol, another two or four tablets of Misoprostol can be taken.
The combined use of Mifepristone and Misoprostol is 99% effective at terminating the pregnancy, whereas Misoprostol on its own has a 92-98% success rate. A successful abortion can be confirmed with a negative pregnancy test three weeks after using abortion pills. You can also arrange to have an ultrasound ten days after using the pills.
