Misoprostol tablets are inserted into the posterior fornix of the vagina after evacuation. Misoprostol tablets can cause the uterus to become excited, so Misoprostol tablets are usually inserted to strengthen the uterine contraction ability and reduce postoperative vaginal bleeding after the cleansing surgery. When inserting misoprostol tablets, first wash your hands, put on a sterile finger cuff and send the misoprostol tablets down the vagina to the deepest part of the vagina, i.e. the posterior vaginal fornix. This is because the medication is best absorbed in the posterior vaginal fornix, where a good therapeutic effect can be achieved. Abdominal pain may occur after the insertion of misoprostol, which is normal and nothing to worry about. After inserting misoprostol tablets into the back of the vaginal fornix after purging, you should try to avoid strenuous exercise, so as to prevent the drug from slipping off and affecting the therapeutic effect. If the abdominal pain is not relieved for a long time, you can go to the hospital for examination.
