After taking Misoprostol generally two hours before eating is more appropriate. Usually, Misoprostol is used for medical abortion, which requires three days of medication, with Mifepristone on the first two days and Misoprostol on the third day. Misoprostol can cause contractions and expel the embryo sac in about an hour after taking it. Doctors and nurses need to observe the expulsion of the embryo and the vaginal bleeding during this process. When there is any abnormality in the expulsion of the embryo sac, or when there is more vaginal bleeding, additional medication is needed to make the expulsion of the embryo better. If you eat too early at this time, it will affect the absorption of the medicine and the observation effect, so it is more appropriate to eat after the whole process of medical abortion is completed.
