Usually breastfeeding after at least 72 hours between levofloxacin shots, when the residual levofloxacin content is basically undetectable in the breast milk, you can breastfeed normally. Levofloxacin is a quinolone drug and is generally not recommended for use during breastfeeding, as this drug will enter the baby’s body through breast milk and may cause the baby’s cartilage and ligaments to develop poorly. However, if you need to treat the disease by levofloxacin, it is recommended to breastfeed three days after the injection of levofloxacin, because the complete metabolism of levofloxacin in the body takes about 72 hours, 72 hours after the body of levofloxacin drug content in the mother’s body is basically metabolized, and generally will not be entered into the baby’s body through the breast milk. It is recommended that patients who need to be treated with levofloxacin should follow the doctor’s instructions to strictly use the drug, and it is not recommended to blindly use the drug on their own.
