RU486: Approval Status and Important Considerations - Obstetrics and Gynecology

More Info

RU486, also known as mifepristone, is a medication primarily used for medical abortion and is often combined with another medication called misoprostol. In the United States, mifepristone was approved by the Food and Drug Administration (FDA) in 2000 for use in terminating early pregnancies, specifically up to 10 weeks gestation. The approval came after extensive clinical trials that demonstrated its safety and efficacy when used under medical supervision.

When considering the use of RU486, there are several important factors and considerations to keep in mind:
1. Eligibility: Mifepristone is indicated for women who are within the first 10 weeks of pregnancy. It is essential to confirm the duration of the pregnancy through appropriate medical evaluations, such as an ultrasound.

2. Medical Supervision: The use of RU486 should always be conducted under the supervision of a qualified healthcare provider. This is crucial for ensuring that the procedure is safe and that the patient receives appropriate follow-up care.

3. Dosage and Administration: The typical regimen involves taking mifepristone orally, followed by misoprostol taken 24 to 48 hours later. The misoprostol induces contractions to expel the pregnancy. It is important to follow the prescribed dosage and timing to ensure the effectiveness of the treatment.

4. Side Effects: Common side effects of mifepristone include cramping, bleeding, nausea, vomiting, diarrhea, and fatigue. While these are generally mild to moderate, it is essential to be aware of them and to contact a healthcare provider if they become severe or if there are any concerns.

5. Potential Complications: Although serious complications are rare, they can occur. These may include heavy bleeding, infection, or incomplete abortion, which may require additional medical intervention. Patients should be informed about the signs of complications, such as severe abdominal pain, fever, or excessive bleeding, and should seek medical attention if they experience these symptoms.

6. Emotional Support: The decision to terminate a pregnancy can be emotionally challenging. It is important for patients to have access to counseling and support services to help them cope with their feelings and to discuss any concerns they may have about the procedure.

7. Legal Considerations: The legal status of mifepristone can vary by state. Some states have enacted laws that impose additional restrictions on its use, including mandatory waiting periods or counseling. It is important to be aware of the laws in your area regarding medical abortion.

8. Follow-Up Care: After taking mifepristone and misoprostol, a follow-up appointment with a healthcare provider is typically recommended to ensure that the abortion is complete and to monitor the patient's recovery.

In summary, RU486 (mifepristone) is an FDA-approved medication for medical abortion, but its use requires careful consideration and medical supervision. Patients should be informed about the procedure, potential side effects, and the importance of follow-up care. If you have further questions or concerns about RU486, it is advisable to consult with a healthcare provider who can provide personalized information and support.
