What is the abortion pill?

The abortion pill, also called medication abortion, is a safe and effective way to end an early pregnancy. 

How does the abortion pill work?

“Abortion pill” is the common name for using two different medicines to end a pregnancy: mifepristone and misoprostol.

First, you take a pill called mifepristone. Pregnancy needs a hormone called progesterone to grow normally. Mifepristone blocks your body’s own progesterone, stopping the pregnancy from growing.

Then you take the second medicine, misoprostol, either right away or up to 48 hours later. This medicine causes cramping and bleeding to empty your uterus. It’s kind of like having a really heavy, crampy period, and the process is very similar to an early miscarriage. If you don’t have any bleeding within 24 hours after taking the second medicine, call your nurse or doctor.

Your doctor or nurse will give you both medicines at the health center. When and where you’ll take them depends on state laws and your health center’s policies. Your doctor or nurse will give you detailed directions about where, when, and how to take the medicines. You may also get some antibiotics to prevent infection.

How effective is the abortion pill?

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

For people who are 8 weeks pregnant or less, it works about 94-98 out of 100 times.

For people who are 8-9 weeks pregnant, it works about 94-96 out of 100 times.

For people who are 9-10 weeks pregnant, it 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, it works about 87 out of 100 times. If you’re given an extra dose of medicine, it works about 98 out of 100 times.

The abortion pill usually works, but if it doesn’t, you can take more medicine or have an in-clinic abortion to complete the abortion.

Why do people choose the abortion pill?

Depending on where you live, you may be able to get a medication abortion up to 77 days (11 weeks) after the first day of your last period. If it has been 78 days or more since the first day of your last period, you can have an in-clinic abortion to end your pregnancy.

Questions from patients:

RU-486 is the former name of mifepristone — one of the medications that you take to have a medication abortion. RU-486 is now called "the abortion pill" or "Mifeprex" (the brand name for mifepristone).

RU-486 was developed in the 1980s. It's been safely used in Europe since 1987, and in the US since 2000.

RU-486 blocks a hormone that your body needs to continue a pregnancy. It works best when you use it with another medication called misoprostol, which causes bleeding to empty your uterus.

The RU-486 abortion pill is a safe and effective way to end an early pregnancy.

Medication abortions, or the abortion pill are available at medical clinics all over the nation. If you are in New York, Parkmed NYC provides abortion services as well as financial assistance to those who qualify.
