A medication abortion usually begins to respond around 2 hours after taking misoprostol on day 3, and a few pregnant women don’t respond for several days or may never respond. Medication abortion requires two medications, one is Mifepristone and the other is Misoprostol. Generally, mifepristone is taken on the 1st day under the guidance of a professional gynecologist, continued once on the 2nd day, and misoprostol on the 3rd day, and reactions to the medication abortion, such as abdominal pain, vaginal bleeding, and discharge of the pregnancy, may occur in about 2 hours. A few pregnant women are not sensitive to the medicinal properties of mifepristone and misoprostol, and may have a medication abortion reaction after a few days or may never have a reaction. Therefore, it is important to observe the changes after taking medication for abortion. Once abnormalities are detected, such as excessive vaginal bleeding, which may easily lead to hemorrhage, it is recommended to go to a regular hospital as soon as possible to take emergency treatment measures in a timely manner.
