Is the Abortion Pill the Same as Plan B or the Morning-After Pill?
If you’re facing an unexpected pregnancy, you may have come across terms like Plan B, the morning-after pill, and the abortion pill while searching for answers. Because these medications are often discussed in similar conversations, it’s common to wonder whether they’re the same thing.
The short answer is no. Plan B (the morning-after pill) is a form of emergency contraception that is intended to help prevent pregnancy after unprotected sex or contraceptive failure. The abortion pill, also called a medication abortion, is used to end an existing pregnancy. Although both medications relate to pregnancy, they work in very different ways and are used at different stages. According to the American College of Obstetricians and Gynecologists (ACOG), emergency contraception works primarily by delaying or preventing ovulation, whereas medication abortion is used after pregnancy has been established.
Understanding the difference is important because each medication has a different purpose, timing, and medical considerations. Misunderstanding how these medications work can lead to confusion about what options may or may not be appropriate for your situation.
If you’re looking for accurate abortion pill information, start by understanding what the abortion pill is, how it works, and the steps involved before making a pregnancy decision. Our Abortion Pill Information Hub provides evidence-based information about medication abortion, pregnancy confirmation, ultrasounds, and pre-abortion screening to help you make an informed decision.

What Is Plan B (the Morning-After Pill)?
Plan B is a brand of emergency contraception, sometimes called the morning-after pill. It is designed to help reduce the chance of pregnancy after unprotected sex or if a birth control method fails, such as a broken condom or missed birth control pills. Other emergency contraceptive pills are also available, including generic versions containing levonorgestrel and another prescription option called ella® (ulipristal acetate). While these medications differ slightly, they all serve the same general purpose: to help prevent pregnancy before it begins.
How Does Plan B Work?
Many individuals ask, “How does Plan B work?” or “How does the morning-after pill work?” Plan B contains levonorgestrel, a hormone that works primarily by delaying or preventing ovulation (the release of an egg from the ovary). If ovulation is delayed until sperm are no longer present, fertilization is less likely to occur.
Because Plan B works before pregnancy begins, it is generally most effective when taken as soon as possible after unprotected sex. However, timing, where you are in your menstrual cycle, and other individual factors can all influence how well emergency contraception works.
Does Plan B Work If You’re Already Pregnant?
Two common questions are “Does Plan B work if you’re pregnant?” and “Does Plan B terminate pregnancy?” The answer is no.
Plan B does not end an existing pregnancy and does not cause an abortion. Once a pregnancy has been established, emergency contraception will not terminate it or affect its progression.¹
If you think you may already be pregnant or have a positive pregnancy test, it’s important to understand your situation before making any decisions. Confirming the pregnancy with a medical-grade pregnancy test and an ultrasound can provide important information about how far along the pregnancy is and what options may be available.
What Is the Abortion Pill?
The abortion pill, also known as a medication abortion or medical abortion, is a method used to end an existing pregnancy during the early weeks of pregnancy. Unlike Plan B or other forms of emergency contraception, the abortion pill is not intended to prevent pregnancy. Instead, it is used after a pregnancy has been established.
A medication abortion typically involves two prescription medications:
- Mifepristone, which blocks the hormone progesterone that is needed to support a pregnancy.
- Misoprostol, which is taken afterward to cause the uterus to contract and expel the pregnancy tissue.
These medications work together to end an existing pregnancy and are different from emergency contraceptive pills, which work before pregnancy begins.
How Does the Abortion Pill Work?
Many people searching for abortion pill information want to understand how the medication works. While every person’s experience is different, the abortion pill process involves taking the two medications in sequence.
Because medication abortion is used after pregnancy has begun, a pre-abortion screening should be recommended to first confirm:
- That you are pregnant
- How far along the pregnancy is (gestational age) through an ultrasound.
- That the pregnancy is located inside the uterus (to rule out an ectopic pregnancy).
- If you have or are at risk of having any STD.
