Dosing of Mifepristone and Misoprostol for Medical Abortion

The abortion pill is very effective. The effectiveness depends on how far along you are in your pregnancy when you take medicine.

• For people who are 8 weeks pregnant or less, one kit (Mifepristone 200mg + Misoprostol 800 mcg) works about 94-98 out of 100 times.
• For people who are 8-9 weeks pregnant, one kit (Mifepristone 200mg + Misoprostol 800 mcg) works about 94-96 out of 100 times.
• For people who are 9-10 weeks pregnant, one kit (Mifepristone 200mg + Misoprostol 800 mcg) works about 91-93 out of 100 times. If you’re given an extra dose of medicine, it works about 99 out of 100 times.
• For people who are 10-11 weeks pregnant, one kit (Mifepristone 200mg + Misoprostol 800 mcg) works about 87 out of 100 times. If you’re given an extra dose of medicine, it works about 98 out of 100 times.
