RU486: Pregnancy Risks and Considerations After Use

After taking RU486..?

Hello doctor: I would like to ask, after taking RU486 in November 2004, how long will it take before I can get pregnant? If I do not get my period in January 2005 (assuming I am pregnant), what problems could this cause? If I am indeed pregnant, will the child be able to be born? Will there be any issues?

Ning, 20~29 year old female. Ask Date: 2005/01/25

Dr. Dai Qihan reply Obstetrics and Gynecology

The use of RU486 is only effective for the current pregnancy.
If you confirm a pregnancy in January, you should be mindful of uterine contractions to avoid miscarriage.

RU486, also known as mifepristone, is a medication that has been approved for use in medical abortions. It works by blocking the hormone progesterone, which is necessary for the maintenance of pregnancy. When considering the use of RU486 and its implications for future pregnancies, there are several important factors to keep in mind.

First and foremost, after taking RU486, it is generally recommended to wait at least one menstrual cycle before attempting to conceive again. This allows the body to return to its normal hormonal balance and ensures that any potential residual effects of the medication have diminished. While some women may conceive shortly after using RU486, it is advisable to consult with a healthcare provider to discuss individual circumstances and any potential risks.

If you find yourself missing your period shortly after taking RU486, it is important to take a pregnancy test to determine whether you are pregnant. If you are indeed pregnant after having taken RU486, there are several considerations to keep in mind. Research indicates that while there may be a risk of complications, many women have gone on to have healthy pregnancies and deliveries after using RU486. However, there is also a possibility of congenital abnormalities, particularly if the medication was taken during the early stages of pregnancy.
The concern regarding the health of the fetus is valid, as some studies have suggested a potential association between the use of RU486 and certain birth defects. However, it is crucial to note that the majority of studies have not found a direct causal link between RU486 and significant teratogenic effects. In fact, the risk of congenital anomalies appears to be similar to that of the general population when the medication is used as directed.

If you suspect that you might be pregnant after taking RU486, it is essential to seek medical advice promptly. A healthcare provider can perform an ultrasound to assess the viability of the pregnancy and determine the best course of action. If the pregnancy is confirmed, the provider will discuss the potential risks and benefits of continuing the pregnancy, taking into account your medical history and any previous use of RU486.

In summary, while it is possible to conceive after using RU486, it is advisable to wait at least one menstrual cycle before trying to become pregnant again. If you miss your period shortly after taking the medication, it is important to take a pregnancy test and consult with a healthcare provider for further evaluation. The risks associated with a pregnancy following the use of RU486 can vary, and a healthcare professional can provide personalized guidance based on your specific situation. Always prioritize open communication with your healthcare provider to ensure the best outcomes for your reproductive health.
