Effects of Intercourse After Taking RU486: What You Need to Know

After taking the first dose of RU486?

I would like to ask if having unprotected intercourse on the same day after taking the first dose of the medication will have any effects.
Is there a possibility of becoming pregnant again?

Dear Fei Fei,
Since you were still in a state of pregnancy at the time of receiving the first dose, there is no possibility of becoming pregnant again immediately.
However, if your partner does not use condoms or any form of contraception after the medication-induced abortion is complete, there is still a chance of becoming pregnant.
I recommend that you discuss a birth control plan with your obstetrician-gynecologist.
Using condoms by the male partner, or the female partner using oral contraceptives or an intrauterine device (IUD), are all effective methods.

More Info

RU486, also known as mifepristone, is a medication used for medical abortion. It works by blocking the hormone progesterone, which is necessary for the pregnancy to continue. When taken in combination with another medication called misoprostol, it can effectively terminate an early pregnancy. Understanding the effects of intercourse after taking RU486 is crucial for those considering this option.

When a person takes RU486, it is typically the first step in a two-part regimen for a medical abortion. After taking RU486, it is recommended to wait for a certain period before engaging in sexual intercourse. The primary reason for this recommendation is that the medication is designed to terminate a pregnancy, and engaging in sexual activity shortly after taking it could lead to confusion regarding the effectiveness of the abortion process.

If intercourse occurs after taking RU486 but before the follow-up medication (misoprostol) is administered, there is a potential risk of becoming pregnant again. This is because RU486 does not provide immediate contraception; it only works to terminate an existing pregnancy. Therefore, if ovulation occurs and sperm is present, there is a possibility of a new pregnancy.

It is important to note that the timing of the follow-up medication is critical. Misoprostol is usually taken 24 to 48 hours after RU486, and it induces contractions to expel the pregnancy tissue. If sexual intercourse occurs after taking RU486 but before misoprostol, the effectiveness of the abortion may not be fully realized until the follow-up medication is taken and the body has expelled the pregnancy.

In summary, having intercourse after taking RU486 can potentially lead to a new pregnancy if it occurs before the follow-up medication is taken and if ovulation has not yet been suppressed. It is advisable to consult with a healthcare provider for personalized guidance and to discuss the timing of sexual activity in relation to the medical abortion process. Additionally, using contraception during this time is highly recommended to prevent unintended pregnancies.

In conclusion, if you have taken RU486 and are considering sexual intercourse, it is essential to understand the implications and risks involved. Always consult with a healthcare professional for advice tailored to your specific situation and to ensure that you are fully informed about the process and any necessary precautions.
