Medication abortion is commonly performed using medicines that cause a pregnancy to end and the uterus to empty. Depending on the medical circumstances and the regimen prescribed, medication abortion may involve mifepristone and misoprostol together or misoprostol alone.
This article focuses on how mifepristone and misoprostol work together and what someone may experience during the process.
What Medicines Are Used for a Medication Abortion?
There are two commonly discussed medication approaches:
-
Mifepristone followed by misoprostol
-
Misoprostol used without mifepristone in certain circumstances
The appropriate approach depends on factors such as pregnancy duration, medical history, local clinical practice, and the guidance of a qualified healthcare professional.

How Will I Know What to Do With Abortion Pills?
Before using abortion medication, you should receive instructions from a qualified healthcare professional.
Your clinician may discuss:
-
How far along the pregnancy is
-
Your medical history
-
Which medicines are appropriate
-
How and when to take the prescribed medication
-
Possible side effects
-
Follow-up care
-
Warning signs that require medical attention
Depending on the healthcare setting, consultation may take place in person or through an appropriate remote healthcare service.
Always follow the instructions provided specifically for you. Do not change the medication, dose, timing, or route of administration without professional guidance.
How Do Mifepristone and Misoprostol Work?
When the two medicines are used together, they have different roles.
Mifepristone blocks progesterone, a hormone that helps maintain pregnancy. Blocking progesterone causes changes that help the pregnancy separate from the uterine lining.
Misoprostol causes the uterus to contract. These contractions lead to cramping and bleeding and help the uterus expel pregnancy tissue.
The combination is highly effective for medication abortion during early pregnancy when used according to an appropriate medical regimen.
What Happens After Misoprostol?
After misoprostol is used, cramping and vaginal bleeding commonly occur.
The intensity and timing can vary. Some people experience strong cramps and heavy bleeding, while others have a less intense experience.
Blood clots and pregnancy tissue may pass during the process. After the pregnancy tissue passes, cramping and bleeding generally begin to decrease.
Because individual circumstances vary, your healthcare professional should explain what symptoms you should expect and what to do if they differ from the expected pattern.
How Is Misoprostol Administered?
Misoprostol can be administered through different routes depending on the prescribed regimen. Routes may include:
-
Buccal administration, where the medicine is placed between the cheek and gums
-
Sublingual administration, where the medicine is placed under the tongue
-
Vaginal administration
The correct route, dose, timing, and number of doses depend on the clinical situation and the regimen prescribed.
Do not choose an administration method or change a prescribed regimen on your own. Follow the exact instructions given by your doctor, nurse, or other qualified healthcare professional.
What Can I Take for Cramping or Nausea?
Cramping is an expected part of medication abortion because misoprostol causes the uterus to contract.
A healthcare professional can advise you about appropriate pain relief based on your medical history and other medications you take.
Some people may also experience nausea, vomiting, diarrhea, chills, dizziness, or tiredness.
If medication for pain or nausea is recommended or prescribed, use it according to the instructions provided.
How Do I Know If the Abortion Pill Worked?
Follow-up helps determine whether the medication abortion was successful.
Your healthcare professional may recommend a specific pregnancy test, blood testing, an ultrasound, or another form of follow-up depending on your circumstances.
A regular home pregnancy test can remain positive for some time after an abortion because pregnancy hormones do not disappear immediately. Therefore, testing too soon may not accurately show whether the abortion was successful.
Your healthcare provider can tell you when and how to complete follow-up testing.
What If the Abortion Does Not Work Completely?
Medication abortion is highly effective, but in some cases the pregnancy may continue or pregnancy tissue may remain in the uterus.
If this happens, a healthcare professional can discuss the available options. Depending on the circumstances, additional medication or an in-clinic procedure may be recommended.
Do not take additional medication without speaking with your healthcare provider.
What If There Is No Bleeding?
Bleeding generally occurs after misoprostol, but the timing can vary.
If you have no bleeding within 24 hours after using misoprostol, contact your healthcare professional for advice.
Do not assume that taking additional medication is appropriate without receiving medical guidance.
When Should I Seek Medical Care?
Although serious complications are uncommon, it is important to understand warning signs.
Contact a healthcare professional if you experience symptoms that concern you, particularly severe or worsening abdominal pain, unusually heavy bleeding, persistent fever, fainting, or other symptoms that your healthcare provider has identified as requiring urgent attention.
If you believe you may have a medical emergency, seek emergency medical care.
How Soon Can Pregnancy Occur Again?
Fertility can return quickly after an abortion, sometimes before the next menstrual period.
If you do not want another pregnancy, discuss contraception with your healthcare professional. They can explain when different contraceptive methods can be started and which options may be appropriate for you.
