Introduction

After taking mifepristone, the endometrium undergoes necrosis and degeneration, and the cervical os becomes relaxed. Most people do not experience significant vaginal bleeding after taking this medication alone. However, some individuals who are particularly sensitive to the drug or who already have slight bleeding upon admission may experience bleeding after taking it. The absence of bleeding after medication is normal. In most cases, bleeding and expulsion of the gestational sac occur after taking misoprostol.

Mife refers to mifepristone. It is normal not to experience bleeding on the second day after taking mifepristone. You should continue taking the medication as instructed to terminate the pregnancy and must not stop the medication arbitrarily. Also, monitor for the expulsion of the gestational sac. Detailed explanation is as follows:

Mifepristone is a progesterone receptor antagonist, typically used in combination with misoprostol for medical abortion. After taking mifepristone, the uterine decidua undergoes necrosis and degeneration, and the cervix becomes relaxed. Most individuals who take only this single medication do not experience significant vaginal bleeding. However, some people who are particularly sensitive to the drug or who already had slight bleeding upon hospital admission may experience bleeding after taking the medication.

Not experiencing bleeding after taking the medication is considered normal. Bleeding and expulsion of the gestational sac usually occur after taking misoprostol.

It is recommended to continue taking the medication as directed. After completing the course, observe whether the gestational sac has been expelled and be sure to follow up with a post-abortion checkup.

How long does it take for mifepristone to take effect after taking the medication?

Mifepristone is a progesterone receptor antagonist commonly used for medical termination of pregnancy. It works by inhibiting the progesterone's maintenance effect on the endometrium, leading to endometrial shedding, thereby preventing further embryonic development and ultimately resulting in expulsion from the body. Typically, within 24 to 48 hours after taking the medication, intermittent uterine contractions and vaginal bleeding occur, indicating that the drug is taking effect.
