If your doctor has prescribed the mifepristone and misoprostol combination for a medical abortion, you probably have a dozen questions right now. How much do you take? When do you take the second pill? Can you take both on the same day? What if something feels wrong afterward?
This guide walks through exactly how to take mifepristone and misoprostol combination, the correct dosing and timing, and the signs that mean you should call your provider right away.
Quick answer: Mifepristone 200 mg is taken by mouth first. Misoprostol 800 mcg follows 24 to 48 hours later, most commonly held in the cheek pouches (buccal route) rather than simply swallowed. This is the FDA-approved regimen for pregnancy through 10 weeks (70 days) gestation.
This combination should only be used under the guidance of a licensed healthcare provider, after confirming the pregnancy is in the uterus and within the approved gestational window. Laws and access around this medication vary by country and by state, so check what’s legally available and permitted where you live before proceeding. Nothing here replaces a medical consultation.
Overview: How Mifepristone and Misoprostol Work Together
Mifepristone and misoprostol are the two medicines used together for medical abortion in early pregnancy. Mifepristone comes first and blocks the hormone that keeps a pregnancy going. Misoprostol follows a day or two later and empties the uterus. Used correctly, this two-step regimen is highly effective, with U.S. clinical trial data showing a complete abortion in roughly 97% of cases without needing a follow-up procedure, according to current FDA prescribing information. The rest of this guide walks through the dosing, timing, what to expect, and when to seek help.
Quick Facts: Mifepristone and Misoprostol Dosage Fact Sheet
| Medication 1 | Mifepristone, 200 mg, taken orally |
| Medication 2 | Misoprostol, 800 mcg (four 200 mcg tablets), most often buccal |
| Timing | Misoprostol taken 24 to 48 hours after mifepristone |
| Approved gestational limit (U.S.) | Through 10 weeks (70 days) since last period |
| Typical success rate | About 97% complete abortion without further procedure |
| Follow-up | Recommended 7 to 14 days after mifepristone |
| Prescription status | Prescription-only, requires a licensed provider |
A note on history: this wasn’t always the regimen. The original Mifeprex label, approved by the FDA in 2000, called for 600 mg of mifepristone followed by 400 mcg of oral misoprostol on an in-clinic visit, and only covered pregnancies through 49 days. The FDA updated the regimen in 2016 to the lower-dose, buccal-misoprostol version described in this guide, after years of research showed it worked just as well with fewer clinic visits.
Important: This Combination Does Not Treat an Ectopic Pregnancy
Before anything else, one warning needs to come first. Mifepristone and misoprostol are approved only for a pregnancy located inside the uterus. If you have severe or one-sided abdominal pain, pain in your shoulder tip, fainting, or sudden weakness at any point, this could signal an ectopic pregnancy and needs emergency medical attention right away, regardless of when you last took either medication.

What Is the Mifepristone and Misoprostol Combination? (MTP Kit Explained)
Mifepristone and misoprostol are two different medicines that work together to end an early pregnancy. This two-drug approach is often sold as a mifepristone and misoprostol tablets kit, sometimes called an MTP kit, and it’s approved for use through 10 weeks (70 days) of pregnancy, counted from the first day of your last menstrual period.
Mifepristone is a progesterone blocker. Progesterone keeps a pregnancy attached to the uterine wall, so once mifepristone blocks it, the pregnancy can no longer continue to grow. Misoprostol comes in next. It makes the uterus contract and pushes the pregnancy tissue out, similar to a heavy, crampy period.
Used alone, misoprostol works, but success rates are noticeably lower than the combination. That’s exactly why doctors prescribe the two together rather than picking just one.
A quick note on gestational age: it’s calculated from the first day of your last period, not from conception. If your periods are irregular or you’re unsure of your dates, your provider may use an ultrasound or exam to confirm how far along you are, since this affects which regimen is appropriate. An ultrasound isn’t automatically required for everyone; the World Health Organization notes that a physical exam and menstrual history are usually enough, and imaging is used mainly when dates are uncertain or another concern needs checking.
How to Take Mifepristone and Misoprostol Combination for Abortion: Step-by-Step
Here’s the regimen most providers follow, based on FDA-approved dosing.
Step 1: How to Take Mifepristone by Mouth (Day One)
You’ll take one 200 mg tablet of mifepristone by mouth, swallowed with water, just like any other pill. There’s no need to take it with food, though a light meal beforehand can help settle your stomach.
At this stage, you likely won’t notice much. Some women feel mild cramping or spotting, but many feel completely normal. That’s expected. Mifepristone is quietly cutting off the pregnancy’s hormonal support, and the real physical process begins once you take misoprostol.
If you vomit within an hour of taking mifepristone, call your provider. Depending on how soon after the dose it happened, you may need a replacement dose, so don’t just assume it will work anyway or take another tablet on your own.
Step 2: Best Time to Take Misoprostol After Mifepristone (Wait 24 to 48 Hours)
Best time to take misoprostol after mifepristone: wait at least 24 hours, and generally no more than 48 hours, before taking misoprostol. This interval gives mifepristone time to weaken the pregnancy’s attachment to the uterus before misoprostol triggers contractions.
Can I take mifepristone and misoprostol at the same time? Under the FDA-approved regimen, no, the instructions call for this 24-to-48-hour gap. Research on same-day (simultaneous) dosing is mixed: some studies have found it nearly as effective as the interval regimen, while at least one recent trial found a meaningfully lower success rate and a higher chance of the pregnancy continuing when both drugs were taken together. Given that mixed picture, don’t change the timing on your own; follow the interval your provider gave you unless they specifically tell you otherwise.
Can I take misoprostol after 24 hours of mifepristone? Yes. Taking misoprostol anywhere between 24 and 48 hours after mifepristone is the standard, expected approach.
What if more than 48 hours pass before I take misoprostol? Life doesn’t always cooperate with a schedule. A short delay beyond 48 hours doesn’t automatically mean the regimen won’t work, but don’t just guess and proceed on your own. Call your provider to confirm whether to continue as planned or adjust the next step.
Step 3: Misoprostol Dose and How to Take It (Day Two or Three)
Mifepristone and misoprostol dose: the standard dose is 800 mcg of misoprostol, usually four tablets of 200 mcg each.
How should misoprostol be taken? The route matters, and it isn’t the same as simply swallowing the pills:
- Buccal (most common for this regimen): place two tablets in each cheek pouch, between your cheek and gum, and leave them there for 30 minutes. Swallow whatever hasn’t dissolved afterward with water. This causes moderate nausea, more than the vaginal route, less than sublingual.
- Sublingual: place all four tablets under your tongue and let them dissolve for 30 minutes. Absorption is fast this way, which can make side effects, especially nausea, feel more intense than the other routes.
- Vaginal: tablets are inserted into the vagina, typically by the woman herself following her provider’s instructions. This route tends to cause the least nausea, though it may be less practical once bleeding has already started, since blood can affect absorption.
Your provider will tell you which route to use. Don’t switch routes on your own, since effectiveness and side effects vary between them. If you’ve been told to simply swallow the tablets whole with water rather than dissolve them buccally or sublingually, confirm that’s really what was intended, since that isn’t the standard method for this indication.
Before you take misoprostol, many providers recommend taking a pain reliever, such as ibuprofen, about 30 minutes beforehand, along with an anti-nausea medication if one has been prescribed. Taking these ahead of time, rather than waiting until cramping starts, tends to keep symptoms more manageable. Confirm the specific timing and medications with your provider.
Once you start taking misoprostol, follow through with the full dose, even if bleeding begins partway through. Stopping partway can leave the dose incomplete, which affects how well the regimen works.
How many doses of misoprostol should I take orally? Whichever route your provider prescribes, the total dose is still 800 mcg, taken as one round of four tablets. Whether a second round is needed afterward depends on two things: how far along the pregnancy is, and whether bleeding has started. Providers generally consider an additional dose if the pregnancy is close to the upper end of the approved window, or if there’s been no bleeding, clots, or tissue passed within 24 hours of the first round. Don’t decide this on your own; confirm with your provider first.
What to Expect After Taking Misoprostol
Misoprostol usually starts working within one to four hours. Everyone’s experience is a little different, but here’s the general pattern.
Bleeding and cramping. Strong cramping and heavy bleeding, often heavier than a typical period, with clots, usually begin a few hours after misoprostol. It can take up to 24 hours to start. Once it starts, the heaviest part usually lasts around six hours before easing. Pain relief like ibuprofen, a heating pad on your belly, a warm shower, or just changing position can all help with the cramping.
Passing the pregnancy tissue. This often happens within four to five hours, though it can take longer. It may look like a heavy clot or appear lighter in color. It’s safe to dispose of it the same way you would a pad, or flush it, though you can also handle it in whatever way feels right to you personally. It’s also completely normal not to notice any distinct tissue at all; that doesn’t mean the treatment isn’t working.
Other common symptoms. Chills, a low-grade fever, nausea, diarrhea, headache, and fatigue are all common in the first day or so and usually resolve within 24 to 48 hours. Breast tenderness can take a couple of weeks longer to fully settle.
What if I don’t bleed after taking misoprostol? No bleeding within 24 hours of taking misoprostol is not typical and should prompt a call to your provider. It doesn’t automatically mean the medication failed, but it needs to be checked rather than waited out.
Bleeding and spotting can continue on and off for one to two weeks, sometimes longer. Use pads rather than tampons while bleeding is heavy, since they make it easier to track how much you’re losing; tampons are generally fine again once the heavy bleeding has eased.
You can go back to your normal activities, including work, exercise, and sex, whenever you feel ready. There’s no set waiting period, it’s a matter of how your body feels.
How Do I Know the Abortion Worked?
This is one of the most common follow-up questions, and it deserves a direct answer:
- Cramping and heavy bleeding, followed by a gradual taper to lighter bleeding, is a good sign.
- Pregnancy symptoms like nausea and breast tenderness should ease over the following days.
- Home pregnancy tests can still show positive for around four weeks afterward, since the pregnancy hormone hCG takes time to clear. Testing too early can give a misleading result.
- Your provider will usually schedule a follow-up, generally within one to two weeks, which may involve an exam, blood test, ultrasound, or a phone check-in depending on their protocol.
- Ongoing pregnancy symptoms, no bleeding at all, or bleeding that doesn’t taper off are reasons to reach out before your scheduled follow-up.
Mifepristone and Misoprostol Tablets Uses
Beyond ending an early pregnancy, this same drug pairing is sometimes used off-label for managing early pregnancy loss (miscarriage) and, in certain clinical settings, for labor induction later in pregnancy. Dosing and timing differ for these situations, so everything in this guide is specific to medical abortion through 10 weeks gestation. Don’t apply this regimen to a different indication without your provider’s direction.
A note on the outer edge of the window: while the combination is approved through 70 days, some providers can still offer it up to 77 days (11 weeks) in certain cases. Beyond that point, a procedural abortion at a clinic is generally the option available. Whether this applies to you depends entirely on your provider’s assessment, not something to decide on your own.
Mifepristone and Misoprostol Dangers: Side Effects vs. Warning Signs
Common, expected effects
- Cramping
- Heavy bleeding with clots
- Nausea or vomiting
- Diarrhea
- Chills or a mild, short-lived fever
- Headache or dizziness
Call your provider or seek emergency care for
- Soaking through two or more thick pads per hour for two hours in a row
- Fever above 100.4°F (38°C) that lasts more than 24 hours after taking misoprostol
- Severe abdominal pain that doesn’t ease with over-the-counter pain relief
- Foul-smelling vaginal discharge
- Fainting, severe dizziness, or sudden weakness
- No bleeding at all within 24 hours of taking misoprostol
When Is This Combination Not Appropriate? (Misoprostol Contraindications)
Should not be used if you have
- A confirmed or suspected ectopic pregnancy
- Chronic adrenal failure
- Known allergy to mifepristone, misoprostol, or similar medications
- Porphyria
- An IUD still in place (it needs to be removed first)
Needs medical evaluation or extra caution if you have
- A bleeding disorder or you’re taking blood thinners
- Long-term corticosteroid therapy
- Uncertainty about how far along the pregnancy is
- A history of uterine scarring or prior uterine surgery
- You’re currently breastfeeding, or taking other medications or supplements (tell your provider about everything you’re taking beforehand, since some can interact with this regimen)
This distinction matters. Some of these rule the medication out entirely, while others simply mean your provider needs more information before treatment, not that the combination is automatically off the table.
Practical Tips Before You Start
Have pain relief on hand, such as ibuprofen, and take it ahead of misoprostol as your provider directs rather than waiting for cramping to start. Set aside the day you take misoprostol to stay home, near a bathroom, ideally with someone nearby. Stock up on pads for the heavier bleeding days; you can switch to tampons once it lightens. Keep your phone accessible and know in advance who to call and where to go if something feels wrong. And keep your follow-up appointment. Confirming the abortion is complete matters just as much as taking the pills correctly.
How You Might Feel Emotionally
The physical process gets most of the attention, but the emotional side matters too. Some people feel relief, some feel sadness, and many feel a mix of both within the same hour. All of that is normal. If you’re finding it hard to cope, talking to a counselor, a trusted friend, or a support line built for this kind of care can help. You don’t have to manage the emotional part alone, even if you’re handling the physical process at home.
Fertility After Mifepristone and Misoprostol
Ovulation can return quickly after a medical abortion, sometimes within two to three weeks, which means pregnancy is possible again before your next period arrives. If you don’t want to become pregnant right away, talk to your provider about starting contraception, since many methods can begin very soon after treatment.
Final Thoughts
Knowing how to take mifepristone and misoprostol combination correctly, mifepristone first, then misoprostol 24 to 48 hours later via the route your provider specifies, makes a real difference in how effective and comfortable the process is. Skipping the waiting period, guessing at the route, or ignoring warning signs can lower your chances of a complete abortion and raise the risk of complications.
If you’re considering this option, or you’ve already been prescribed the combination and still have questions, reach out to a licensed provider before you begin. The NFH Clinic team is available to answer questions and help you understand each step of the process.
Key Takeaways
- Mifepristone (200 mg, oral) comes first, followed by misoprostol (800 mcg, usually buccal) 24 to 48 hours later.
- Don’t take both medications at the same time or switch the misoprostol route on your own; the timing and method affect how well the regimen works.
- Take pain relief before misoprostol, not after cramping starts, and finish the full dose even if bleeding begins partway through.
- Cramping, bleeding, and passing tissue within a few hours of misoprostol is expected. No bleeding within 24 hours, vomiting soon after mifepristone, or any sign of an ectopic pregnancy all need a call to your provider.
- Keep your follow-up appointment, usually 7 to 14 days later, to confirm the abortion is complete.
- This regimen is approved for pregnancies through 10 weeks (70 days) gestation; anything beyond that needs a different protocol from your provider.
Frequently Asked Questions
How to Take Mifepristone and Misoprostol Combination Orally
Mifepristone, yes, it’s always swallowed by mouth. Misoprostol is different: for this specific regimen, it’s most often held in the cheek (buccal) rather than swallowed outright, since that route works better for ending a pregnancy than swallowing it whole does. Only take misoprostol by mouth if your provider has specifically told you to use that route.
When is misoprostol contraindicated?
Misoprostol shouldn’t be used if you have a known allergy to it or similar medications, a confirmed or suspected ectopic pregnancy, or an IUD still in place. It also calls for extra caution in people with bleeding disorders, uterine scarring, or chronic corticosteroid use. See the contraindications section above for the full list.
What are the dangers of mifepristone and misoprostol?
Used correctly and under medical supervision, serious complications are uncommon. The main risks are heavy bleeding, infection, and an incomplete abortion that needs further treatment. Knowing the warning signs, and calling your provider as soon as they show up, is what keeps this process safe.
How to Use Mifepristone Tablet for Abortion
Swallow one 200 mg tablet with water on day one. Misoprostol follows 24 to 48 hours later, using the route your provider specifies.
How to take misoprostol?
Most commonly, the tablets are placed in the cheek pouches (buccal) and left for 30 minutes. Sublingual and vaginal routes are also used depending on the protocol. Simply swallowing the tablets is not the standard method for this indication unless your provider specifically instructs it.
Can I use the RHAP mife-miso instructions I found online?
Clinical protocols like the Reproductive Health Access Project’s are a useful reference point, but dosing and timing should always be confirmed with your own provider, since regimens can differ slightly by country, clinic, and individual circumstances.
Is this combination safe?
Yes, when used correctly and under medical supervision, mifepristone and misoprostol are considered safe and effective for ending an early pregnancy. As with any medication, there are risks, which is why monitoring and follow-up matter.
What if misoprostol doesn’t work?
If bleeding and cramping don’t start, or the abortion isn’t complete, your provider may recommend an additional dose of misoprostol or a follow-up procedure.
