Intravenous anti-inflammatory drugs, such as antibiotics, are mainly used to prevent infection and are generally performed for high-risk painless abortion patients, while low-risk or normal painless abortion patients can simply take oral anti-inflammatory drugs and motherwort granules after the procedure, without the need for IV treatment.
