Quick Answer: What is medical abortion?
Medical abortion is a nonsurgical way to end an early pregnancy using two prescription medicines: mifepristone, which blocks progesterone, followed by misoprostol, which makes the uterus contract and empty. The combination is about 98% effective. Very heavy bleeding, a fever of 100.4°F (38°C) or higher lasting more than 4 hours, or severe pain needs prompt medical care. [1]
What the research says
The two-medicine regimen works for most people and serious problems are rare. A systematic review of 87 trials with 47,283 people found treatment failure in 4.8% and an ongoing pregnancy in 1.1%; only 0.3% were hospitalized and 0.1% needed a blood transfusion. (Raymond et al., Contraception, 2013) [2]
Telemedicine care performed as well as in-person care. In a national cohort of 52,142 medical abortions, treatment success was 98.8% with a telemedicine-hybrid model versus 98.2% with traditional in-person care, serious adverse events stayed at 0.02% to 0.04%, and 96% of people were satisfied with telemedicine. (Aiken et al., BJOG, 2021) [3]
Telehealth medication abortion was effective and safe. Among 6,034 abortions provided by telehealth, 97.7% were complete without further intervention, and 99.8% were not followed by a serious adverse event. (Upadhyay et al., Nature Medicine, 2024) [4]
Key takeaways
Medical abortion uses two medicines, mifepristone and then misoprostol, to end a pregnancy in its early stages. [1]
The combination is about 98% effective, and complications are rare. [1]
Bleeding and cramping usually start 1 to 4 hours after misoprostol, and the process takes about 2 to 6 hours. [1]
Heavier bleeding lasts 1 to 2 days and usually eases over 2 to 3 weeks. [1]
A follow-up visit or call within 2 to 5 weeks confirms the pregnancy has ended. [1]
There are no long-term health risks, and future pregnancies are not affected unless complications occurred. [1]
What is a medical abortion?
A medical abortion is a procedure that uses prescription pills, rather than surgery, to end a pregnancy in its early stages. It is also called a medication abortion. [1]
The most common regimen uses two pills taken in order:
Medical abortion is a first-trimester option. Later in pregnancy, a clinician may discuss a procedure instead, such as an in-clinic (aspiration) abortion or a dilation and curettage (D&C). [1]
Medical abortion is common. Over half of all abortions in the United States are medical abortions. [1]
Why is a medical abortion performed?
A medical abortion is performed for different personal and medical reasons, and the decision is highly personal. [1] Common reasons include:
Ending an unwanted pregnancy. [1]
Concern about passing on a congenital or inherited disease. [1]
A pregnancy that could be life-threatening to carry. [1]
Completing a miscarriage that has not passed on its own (a missed abortion). The same pills are used for this. [1]
A healthcare provider who knows your medical history can help you weigh your options. [1]
When can someone have a medical abortion?
Medical abortion with mifepristone and misoprostol is approved by the U.S. Food and Drug Administration (FDA) as safe and effective up to 10 weeks of pregnancy, and evidence shows it is also safe and effective beyond 10 weeks. [1] The regimen can be used up through 12 weeks for an at-home abortion. [1] You can read the FDA's own summary on its mifepristone information page.
Certified clinicians and pharmacies can provide the medicines in healthcare settings and by mail, which makes care by telehealth possible. [1]
Laws on medical abortion vary by location. In the United States, state law decides whether it is legal and, where it is, can set: [1]
What local law may control | Examples |
Who can prescribe | Some areas allow only physicians |
Type of visit | One or more in-person visits may be required; telemedicine may be banned |
What happens at the visit | A pregnancy ultrasound may be required |
Who should not have a medical abortion?
Medical abortion is not a safe option for everyone, so your provider will review your medical history first. [1]
Not a safe option if you… | Note |
Are too far along in pregnancy | — |
Are allergic to the medicines used | — |
Have an ectopic pregnancy (outside the uterus) | — |
Use long-term corticosteroids | — |
Have an intrauterine device (IUD) | Becomes an option once the IUD is removed |
Have a blood clotting disorder, significant anemia or chronic adrenal failure | — |
Don't have access to emergency care | — |

How do you prepare for a medical abortion?
Preparing for a medical abortion starts with an evaluation by a healthcare provider. The exact steps depend on where you have it. [1] Preparation may include:
How does a medical abortion work?
A medical abortion works in two steps: the first medicine stops the pregnancy, and the second empties the uterus. [1] Follow the instructions exactly as prescribed. [1]

Mifepristone (step 1) | Misoprostol (step 2) | |
Brand names | Mifeprex, RU-486 | Cytotec |
How it is taken | By mouth | Dissolved in the cheek (buccal) or placed in the vagina |
What it does | Blocks progesterone; the uterine lining thins and the pregnancy cannot stay attached | Makes the uterus contract, bleed and expel the pregnancy |
Timing | Taken first | Cheek form: 24 to 48 hours after mifepristone. Vaginal form: 0 to 48 hours after |

What happens during a medical abortion?
During a medical abortion, most of the effects begin shortly after the second pill, misoprostol. [1] You can expect:
How long does a medical abortion take?
A medical abortion takes about 2 to 6 hours after the second pill, although it can take longer. Plan to rest, and have someone you trust with you for care and comfort. [1]
Does medical abortion hurt?
Medical abortion pain feels most like strong period cramps, and the intensity differs from person to person. [1] A heating pad and over-the-counter pain relievers, most often NSAIDs such as ibuprofen, can help. [1] Ask your provider which pain reliever to use and when; taking one about 30 minutes before misoprostol may be suggested. [1]
What should you expect after a medical abortion?
After a medical abortion, vaginal bleeding and cramping are the main side effects. [1] The heaviest bleeding usually comes several hours after misoprostol, then period-like bleeding can continue for several days, and light to moderate bleeding may last several weeks. [1]

How long do you bleed after a medical abortion?
Bleeding after a medical abortion is usually heavier for 1 to 2 days and then lessens over 2 to 3 weeks. [1] The amount varies from person to person and depends on how far along the pregnancy was. [1] Wear sanitary pads until bleeding stops; pads help you see clots and judge blood loss so you can tell your provider. [1]
What happens at the follow-up appointment?
The follow-up after a medical abortion is a visit or call within 2 to 5 weeks to confirm the medicine worked. [1] Your provider may ask you to take a home urine pregnancy test, have lab work or have an ultrasound. [1]
How effective and safe is medical abortion?
Medical abortion with mifepristone and misoprostol is about 98% effective, and complications are rare. [1] Taking every medicine as prescribed matters, because skipping a dose or not following instructions can create health risks. [1]
What are the benefits of a medical abortion?
It can be done early, as soon as you know you are pregnant or learn of an early miscarriage. [1]
Passing the pregnancy may feel more natural than having a procedure. [1]
You can be at home, or somewhere that feels safe, for the cramping and bleeding. [1]
You can have the support people you choose with you. [1]
What are the risks of a medical abortion?
Risk | Detail |
Failure to end the pregnancy or retained pregnancy tissue | — |
Heavy bleeding that won't stop | Could lead to a need for a D&C |
Diarrhea and digestive pain | — |
Allergic reaction to the medicines | — |
Infection | Signs include an unpleasant vaginal odor, a fever of 100.4°F (38°C) or higher lasting more than 4 hours, or feeling very sick even without a fever |
Source: [1]
There are no long-term health risks associated with medical abortion. [1]
How long does recovery take after a medical abortion?
Recovery after a medical abortion varies, but most people feel better the day after the last pill and can return to normal activities within a day or two. [1] Listen to your body and avoid anything that causes pain. [1]
Milestone | Typical timing |
Feeling better | The day after the last pill |
Back to normal activities | Within 1 to 2 days |
Sex, tampons or anything in the vagina | Wait at least 2 to 3 weeks to prevent infection |
Able to get pregnant again | Within 2 weeks |
Period returns | 4 to 6 weeks (the first may be irregular) |

Recovery is not only physical. Feelings can range from relief to sadness, stress or guilt, and all of these are normal. [1] Speaking with a mental health professional, such as a therapist, can help, and your provider can recommend one. [1]
Does medical abortion affect future pregnancies?
Medical abortion should not affect future pregnancies unless there were complications. [1] Keep in mind that pregnancy is possible again within 2 weeks of the abortion. [1]
When should you call a doctor after a medical abortion?
You should contact your healthcare provider after a medical abortion if any of these warning signs appear. [1]
Warning signs that need a call to your provider. Image: rinnit.com
No bleeding 24 hours after taking misoprostol. [1]
Severe bleeding, meaning soaking more than two thick pads within an hour. [1]
Signs of infection: a fever of 100.4°F (38°C) or higher lasting more than 4 hours, foul-smelling vaginal discharge, or feeling very sick (weakness, nausea, vomiting or diarrhea) more than 24 hours after misoprostol, even without a fever. [1]
Severe abdominal or back pain. [1]
No period two months after the abortion. [1]
Symptoms of pregnancy that continue. [1]
