Emergency Contraception (aka Plan B) vs. Medical Abortion Pills: What's the Difference?
When it comes to managing an unplanned pregnancy, two common options are emergency contraception and medical abortion pills (medAB). Though both are related to pregnancy prevention, they work in very different ways and are used at different points in the process. Here’s a simple breakdown:
What it is
Emergency contraception (sometimes called the "morning-after pill" or "Plan B")) is a method used to prevent pregnancy after unprotected sex or contraceptive failure (like a condom breaking). It is not an abortion and will not be effective if you’re already pregnant.
How it works
Emergency contraception works by delaying or preventing ovulation (the release of an egg from the ovary), preventing fertilization, or stopping a fertilized egg from attaching to the uterus. The goal is to prevent pregnancy from happening in the first place.
When to use it
Emergency contraception should be taken as soon as possible after unprotected sex—ideally within 72 hours (but some types can work up to 5 days after).
Examples
The most common types of emergency contraception are Plan B One-Step, Ella, and generic options. At Twentyeight Health, we focus on providing Ella and affordable generic emergency contraception to ensure everyone has access to the care they need.
Unlike Plan B One-Step, Ella and generic options offer more cost-effective solutions, often covered by insurance or Medicaid. Twentyeight Health makes access to these options simple and affordable.
Does it work after pregnancy begins?
No, emergency contraception does not work if you’re already pregnant.
Important to Know About Expiration
Ella has a shelf life of three years, meaning you can safely purchase and store one or two tablets at home for future use in case of an emergency. Always check the expiration date on the box before taking it. Store your emergency contraception in a dry, dark place at room temperature (68-77 degrees) — avoid bathroom cabinets where it can get steamy.
What they are
Medical abortion pills are used to end an existing pregnancy. They are an option for people who are early in their pregnancy (usually up to 10 weeks). This is sometimes referred to as an "abortion pill.”
How it works
The first pill, mifepristone, blocks the hormone progesterone, which is needed for the pregnancy to continue. After a few days, the second pill, misoprostol, causes the uterus to contract and expel the pregnancy. This process usually happens at home but should always be done under the care of a healthcare provider.
When to use it
Medical abortion is used after confirming a pregnancy through a test or a visit to the doctor and is typically available for pregnancies up to 10 weeks.
Examples
The most common medical abortion pills include Mifepristone and Misoprostol.
Does it work for contraception?
No, medical abortion pills are only for ending a pregnancy and will not prevent future pregnancies.
Both of these options are safe when used correctly, but they are used at different points in the reproductive process. Emergency contraception is for prevention, while medical abortion is for ending a pregnancy.
