Is Amdinocillin safe while breastfeeding?
Here is what LactMed, the Drugs and Lactation Database published by the U.S. National Institute of Child Health and Human Development (NICHD), reports about Amdinocillin. The text below is quoted from that source — it is not our own verdict.

“No published information” means the studies do not exist yet — not that Amdinocillin is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
