If there is no gynecological inflammation in the examination on the same day, the IUD can be removed, but if there is a gynecological infection that cannot be removed, it has to be treated before the IUD can be removed. The best time for women to remove the IUD is 3-7 days after menstruation, avoid sexual intercourse and go to the hospital for routine examination of leukorrhea, ultrasound and electrocardiogram. If the presence of gynecological inflammation and infection is ruled out through examination, the ring can be removed directly on the same day. However, if there is inflammation, such as vaginitis, pelvic inflammatory disease or cervicitis, the IUD can not be removed for the time being, and it should be removed only after the inflammation is stabilized and cured, so as to avoid infection and aggravation of the condition caused by removing the IUD during the period of inflammation. After the removal of the IUD, we should pay attention to hygiene, prohibit coitus within 2 weeks, take metronidazole, amoxicillin and other drugs to prevent infections as prescribed by the doctor, and avoid douching inside the vagina.
