Mifepristone, also known as RU-486, is a synthetic steroid compound that serves as an antiprogestin medication. It is primarily used for medical abortion in combination with Misoprostol. The drug works by blocking the activity of progesterone, a hormone crucial for maintaining pregnancy. By doing so, Mifepristone initiates the process of abortion, leading to the detachment of the embryo from the uterine wall and the induction of uterine contractions to expel the pregnancy. Besides its use in medical abortion, Mifepristone has shown potential in treating several medical conditions, including Cushing’s syndrome and certain tumors.
Important things to know about Mifepristone:
1. Medical Abortion: Mifepristone, when used in combination with Misoprostol, is an effective and safe option for non-surgical medical abortion during early pregnancy (up to 10 weeks). The medication regimen is typically administered under the guidance and supervision of healthcare professionals.
2. Progesterone Blocker: Mifepristone is an antiprogestin, meaning it blocks the action of progesterone, a hormone crucial for sustaining pregnancy. By doing so, it disrupts the pregnancy, leading to the embryo’s detachment from the uterine wall.
3. Usage for Cushing’s Syndrome: Mifepristone has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of hyperglycemia (high blood sugar levels) in adults with endogenous Cushing’s syndrome who have type 2 diabetes or glucose intolerance and are not candidates for surgery or have not responded well to surgery.
4. Emergency Contraception: Mifepristone may also be used as an emergency contraceptive if administered within a specific time frame after unprotected intercourse. However, its effectiveness for this purpose is generally lower than dedicated emergency contraceptive methods.
5. Off-Label Uses: Mifepristone is sometimes used off-label for medical conditions such as uterine fibroids, induction of labor, and treatment of some types of breast cancer. However, such use is not approved by regulatory authorities and requires careful evaluation by a healthcare professional.
6. Medical Supervision: The administration of Mifepristone for any purpose should be done under the supervision of a qualified healthcare provider. The drug’s use and dosage should be tailored to each individual’s specific medical history and condition.
7. Side Effects: Mifepristone can cause side effects, including but not limited to nausea, vomiting, diarrhea, abdominal pain, and vaginal bleeding or spotting. Serious complications are rare but may include excessive bleeding or infection, which is why medical supervision is crucial.
8. Incomplete Abortion: In some cases, medical abortion using Mifepristone and Misoprostol may not be successful in fully terminating the pregnancy. If an incomplete abortion occurs, a surgical procedure may be necessary to complete the process.
9. Contraindications: Mifepristone is contraindicated in certain medical conditions, such as ectopic pregnancy (a pregnancy outside the uterus), chronic adrenal failure, bleeding disorders, and certain conditions where the use of anticoagulants is required.
10. Mental Health Considerations: Medical abortion can have emotional and psychological effects on some individuals. Counseling and support services should be available to those undergoing the procedure to address any potential mental health concerns.
It’s important to recognize that Mifepristone, though widely used and considered safe when administered appropriately, is a potent medication with potential risks and complications. Therefore, it should only be used under proper medical supervision and guidance. If you or someone you know is considering Mifepristone for any purpose, it is essential to consult a healthcare professional to discuss the individual’s medical history and determine the most appropriate course of action.
Mifepristone, also known as RU-486, is a synthetic steroid compound that serves as an antiprogestin medication. It is primarily used for medical abortion in combination with Misoprostol. The drug works by blocking the activity of progesterone, a hormone crucial for maintaining pregnancy.

Besides its use in medical abortion, Mifepristone has shown potential in treating several medical conditions, including Cushing’s syndrome and certain tumors.
Medical abortion using Mifepristone is a well-established and effective method for terminating early pregnancies up to 10 weeks gestation. It is usually administered in combination with Misoprostol, a prostaglandin medication that helps induce uterine contractions and complete the abortion process. This combination has been proven to be safe and effective, making it a popular choice for individuals seeking a non-surgical abortion option.
Apart from its role in medical abortion, Mifepristone has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of hyperglycemia in adults with endogenous Cushing’s syndrome who have type 2 diabetes or glucose intolerance and are not candidates for surgery or have not responded well to surgery. By blocking the action of cortisol, a hormone produced in excess in Cushing’s syndrome, Mifepristone helps regulate blood sugar levels in affected individuals.
In certain situations, Mifepristone can be used as an emergency contraceptive if administered within a specific time frame after unprotected intercourse. However, it is essential to note that dedicated emergency contraceptive methods, such as copper intrauterine devices or emergency contraceptive pills containing levonorgestrel, are more effective and should be the preferred choice in such cases.
While Mifepristone is primarily used for medical abortion and treatment of Cushing’s syndrome, it is occasionally prescribed off-label for other purposes. Some healthcare providers may use it to manage uterine fibroids or to induce labor in certain situations. Additionally, there have been studies investigating its potential for the treatment of certain types of breast cancer, but this use is not yet approved by regulatory authorities.
As with any medication, the use of Mifepristone should be carefully supervised by a qualified healthcare provider. The drug’s dosage and administration should be tailored to the individual’s specific medical history and condition. While Mifepristone is generally well-tolerated, it can cause side effects, including nausea, vomiting, diarrhea, abdominal pain, and vaginal bleeding or spotting. In rare cases, serious complications such as excessive bleeding or infection may occur, underscoring the importance of medical supervision during its use.
It is crucial for individuals considering Mifepristone for medical abortion or any other purpose to be aware of its contraindications. The medication should not be used in cases of ectopic pregnancy (a pregnancy outside the uterus), chronic adrenal failure, bleeding disorders, or in individuals who require anticoagulant therapy. Proper screening and evaluation by a healthcare professional are essential before initiating treatment.
Beyond the physical aspects, medical abortion can have emotional and psychological effects on some individuals. It is important for healthcare providers to offer counseling and support services to those undergoing the procedure to address any potential mental health concerns.
In summary, Mifepristone is a valuable medication used primarily for medical abortion in combination with Misoprostol. It is also approved for the treatment of hyperglycemia in certain cases of endogenous Cushing’s syndrome. While generally safe and effective when used appropriately, Mifepristone should only be administered under the guidance of qualified healthcare professionals. Individuals considering its use should be informed about potential risks, side effects, and contraindications before making any decisions. Seeking proper medical care and support during this process is essential to ensure the well-being of the individual undergoing treatment.
