Is Prothionamide 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 Prothionamide. The text below is quoted from that source — it is not our own verdict.
Summary of use during breastfeeding
Prothionamide (protionamide) is not approved for marketing in the United States by the U.S. Food and Drug Administration, but is available in other countries. No information is available on the use of prothionamide during breastfeeding. International sources consider breastfeeding to be acceptable during prothionamide use, but mothers should receive 100 mg of pyridoxine daily and the breastfed infant should receive pyridoxine 1 to 2 mg/kg once daily. Monitor the breastfed infant for gastrointestinal disturbances.[1]

“No published information” means the studies do not exist yet — not that Prothionamide 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.
