Misoprostol is often used together with Mifepristone to terminate early pregnancy in women within 49 days of menopause. It usually takes effect about 2-4 hours after taking the drug, and about 80% of women expel the chorion and fetal sac within 6 hours after taking the drug, and about 10% of women expel the chorion and fetal sac within 7 days after taking the drug. Misoprostol tablets are sex hormone drugs that have the effect of softening the cervix, enhancing uterine tone and uterine contractions. Women may experience abdominal pain, vaginal bleeding and other symptoms after taking it. Some patients may experience adverse reactions such as nausea, vomiting, headache, dizziness and weakness. Therefore, misoprostol tablets must be taken under the supervision of a specialist. In addition, patients must fast for 2 hours after taking the drug to avoid affecting its effectiveness. The patient must go to the gynecology department of the hospital for a review 8-15 days after taking the medicine to ensure complete outflow of embryonic tissue, and abortion must be performed to terminate the pregnancy if the drug abortion fails.
