Does metronidazole during breastfeeding affect the child?

Patient's question:

30 years old
Breastfeeding, with a 3-month-old daughter.
How much metronidazole dosage would be harmful to the daughter, causing "blood disorders and neurological disorders"? I was prescribed a 3-day infusion for endometritis yesterday, with 2 bottles of 100ml metronidazole each day. The hospital doctor said it would not affect the child, so I continued breastfeeding after the infusion yesterday. Is there any risk? Should I temporarily stop breastfeeding? Thank you!

Doctor's answer:

Hello: Considering the situation you mentioned, generally after taking medication during breastfeeding, it is usually sufficient to stop medication for one week before resuming breastfeeding for the baby.
Advice: It is recommended that you clearly inform your doctor to ensure they select a medication with minimal impact on the baby. If it is a cephalosporin antibiotic, it is generally sufficient to stop medication for three days. Additionally, drink more water to help dilute the medication and promote its early excretion from the body. Also, make sure to express the milk during the period of stopping breastfeeding to prevent clogged milk.
