The large amount of bleeding after medical abortion needs to be treated according to the different reasons. If the bleeding is caused by incomplete miscarriage or intrauterine infection, it is recommended to carry out ultrasound examination to determine the location of the residue, and to carry out clearance surgery as soon as possible to completely clear out the residue in the uterine cavity to avoid repeated heavy bleeding. If the bleeding is caused by intrauterine infection, it is recommended to take anti-infective drugs orally or intravenously for anti-infective treatment, commonly used anti-infective drugs include cephalosporins, ofloxacin, tinidazole, etc. In addition to symptomatic treatment, you can also take hemostatic drugs such as Yunnan Baiyao and Uterine Blood Tablet, which can effectively relieve the heavy bleeding.
