Generic Mifeprex
Used for Birth Control, Cushing's Syndrome

Mifepristone (Mifeprex) is used together with misoprostol (Cytotec) for medical abortion (using prescribed medications to end a pregnancy). These medications are typically used in people no more than 10 weeks pregnant. In some cases, it can be prescribed to people up to 11 weeks pregnant. Mifepristone (Mifeprex) is only available by prescription in certain U.S. states from certain healthcare providers (including some pharmacies). Taking mifepristone (Mifeprex) with misoprostol (Cytotec) can cause side effects like nausea and cramps. Vaginal bleeding is also an expected symptom after you've taken these abortion pills, but a lot of heavy bleeding can be a sign of serious complications. You'll need to follow up with your provider to make sure your pregnancy has ended completely.

What is Mifepristone (Mifeprex)?

What is Mifepristone (Mifeprex) used for?

How Mifepristone (Mifeprex) works

Mifepristone (Mifeprex) is an antiprogestin medication. It blocks the effects of progesterone, a natural sex hormone that's important in starting and continuing a pregnancy. By blocking progesterone, mifepristone (Mifeprex) prevents a pregnancy from continuing.

Mifepristone (Mifeprex) is taken along with misoprostol (Cytotec). This additional medication causes your uterus to contract and push the pregnancy tissue out of your body. These two medications work together to end a pregnancy.

Pharmacist tips for Mifepristone (Mifeprex)

pharmacist
  • Be sure to discuss with your healthcare provider about what to expect after you take mifepristone (Mifeprex). There can be some side effects such as cramping, nausea, and heavy bleeding.
  • You must follow up with your healthcare provider 1 to 2 weeks after you take mifepristone (Mifeprex). Your provider will need to examine you to make sure the medications worked and that there are no complications.
  • If you need to go to the emergency room or see a different provider for any reason during the process, make sure to let them know you're currently having a medical abortion.
  • Although mifepristone (Mifeprex) with misoprostol (Cytotec) works very well at ending a pregnancy, there's a small chance that it won't work. If this is the case, your healthcare provider will discuss with you about your options to complete the abortion. One possible option is through certain surgical procedures.
  • Let your healthcare provider know about all the medications you're taking, including over-the-counter (OTC) medications and supplements, so they can make sure mifepristone (Mifeprex) is safe for you to take. Certain medications, like carbamazepine (Tegretol), can affect how well mifepristone (Mifeprex) works. Other medications might raise your risk for side effects.
  • Let your healthcare provider know if you're currently breastfeeding when you're discussing plans for medical abortion. Mifepristone (Mifeprex) can pass into your breast milk, but we don't know the effects of this medication in breastfed babies. Mifepristone (Mifeprex) might not be the best option for you.

Common questions about Mifepristone (Mifeprex)

Mifepristone (Mifeprex) can stay in your system for a few days to a few weeks. This is an estimated time frame that's based on the half-life of mifepristone (Mifeprex), which is a measure of how long it takes your body to remove the medication from your system. Keep in mind that how fast the body can get rid of the medication from its system can vary from person to person.

After you take mifepristone (Mifeprex) and misoprostol (Cytotec), vaginal bleeding and cramping normally happens. You also might feel nauseous, dizzy, or have chills. These side effects typically start within the first several hours of taking misoprostol (Cytotec). More specifically, heavy bleeding (sometimes with clots and tissue) usually occurs 1 to 4 hours after taking misoprostol (Cytotec). This is why it's a good idea to find a quiet and comfortable place before you take the medication. Some symptoms get better in the days following the medical abortion, but bleeding and cramping might continue for a few weeks. In fact, some people have had heavy bleeding for about 2 days. But it's typical to see spotting (light bleeding) for 1 to 2 weeks and up to 1 month or longer. To prepare for your medical abortion, review the timeline of when to expect side effects, how to manage them, and when you should get medical help.

No, mifepristone (Mifeprex) is not a morning-after pill (or emergency contraception). Mifepristone (Mifeprex) is used for medical abortion, or ending a pregnancy that's already confirmed. Morning-after pills, like levonorgestrel (Plan B One-Step) and Ella (ullipristal), are used after you've had unprotected sex to prevent a pregnancy from happening in the first place.

Mifepristone (Mifeprex) is FDA approved for medical abortion when it's taken together with misoprostol (Cytotec) for pregnancies up to 10 weeks. But the National Abortion Federation (NAF) guidelines state that this combination of medications can also be used off-label to manage certain miscarriages (or pregnancy loss). Speak with your provider to find out more information about possibly using mifepristone (Mifeprex) to help with miscarriages.

Mifepristone (Mifeprex) is approved for medical abortion when it's taken together with misoprostol (Cytotec) for pregnancies up to 10 weeks. In addition, National Abortion Federation (NAF) guidelines recommend taking this combination regimen for medical abortion and don't mention using mifepristone (Mifeprex) alone. But the guidelines say that it's possible to use misoprostol (Cytotec) alone in certain situations, though this might cause more bleeding than taking the two medications together. Talk to your healthcare provider about the medical abortion plan that's right for you.

Mifepristone (Mifeprex) is taken together with misoprostol (Cytotec) to end a pregnancy. Most people will pass the pregnancy tissue and thus end the pregnancy within 2 to 24 hours of taking misoprostol (Cytotec). Before you start the medical abortion process, make sure you're in an appropriate and comfortable place when you take misoprostol (Cytotec), since it can cause cramps and vaginal bleeding. After taking the medications, you must follow up with your healthcare provider within 1 to 2 weeks to make sure the pregnancy has ended completely.

Mifepristone (Mifeprex) is used with misoprostol (Cytotec) for medical abortions for pregnancies up to 10 weeks. Mifepristone (Mifeprex) can be taken at any time of day. But it might be more important to consider when you take your misoprostol (Cytotec). You'll want to make sure to take misoprostol (Cytotec) at a time where you can find a quiet and comfortable place to get situated. This is because you can start having side effects, like cramping, nausea, and bleeding, within a few hours of taking that medication. Review the timeline of when you should take mifepristone (Mifeprex) and misoprostol (Cytotec), when to expect side effects, and how to manage them to prepare for your medical abortion.

Mifepristone (Mifeprex) requires a prescription from a healthcare provider. You can get mifepristone (Mifeprex) in certain U.S. states from certain clinics, provider's offices, and hospitals. It can also be delivered to your home through mail order from a certified (trained) provider. In January 2023, the FDA allowed mifepristone (Mifeprex) to be picked up at or mail-ordered through certified pharmacies. Mifepristone (Mifeprex) is used with misoprostol (Cytotec), which can be found at many pharmacies with a prescription from your provider. Discuss with your provider about the best way for you to get these two medical abortion medications.

Because of the risks of serious complications, mifepristone (Mifeprex) is only available through a restricted program called the Mifepristone Risk Evaluation and Mitigation Strategies (REMS) program. This program makes sure that you, your healthcare provider, and your pharmacy understand the serious risks of mifepristone (Mifeprex). Only certain healthcare providers who are certified under the Mifepristone REMS program are able to prescribe the medication. As of January 2023, only certain pharmacies that are also certified under this REMS program are able to provide mifepristone (Mifeprex). Visit the mifepristone (Mifeprex) website for more information.

Risks and warnings for Mifepristone (Mifeprex)

Mifepristone (Mifeprex) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Serious infection

Black Box WarningRarely, serious and sometimes life-threatening infections have happened after an abortion happens, including after taking mifepristone (Mifeprex). If you have a fever greater than 100.4ºF for more than 4 hours, severe stomach pain, or tenderness in the pelvic area during the days following your medical abortion, contact your healthcare provider or get emergency help right away. Also get medical attention right away if you experience stomach pain or discomfort, weakness, nausea, vomiting, or diarrhea for more than 24 hours after taking misoprostol (Cytotec). These all might be signs of a serious infection.

Serious vaginal bleeding

Black Box WarningVaginal bleeding is normal and expected during a medical abortion. But if it lasts for a long time and is extremely heavy (soaking through two thick, full-size sanitary pads per hour for two consecutive hours), then go to the emergency room right away. This can be a sign of an incomplete abortion, which needs to be immediately resolved to prevent shock.
