Is Pretomanid 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 Pretomanid. The text below is quoted from that source — it is not our own verdict.
Summary of use during breastfeeding
No information is available on the use of pretomanid during breastfeeding, although the estimated dose for a breastfed infant is low. If pretomanid is required by the mother, it is not a reason to discontinue breastfeeding, but until more data become available, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.

Levels in milk
Maternal Levels. Using a computed milk-to-plasma ratio of 0.89, one group of authors estimated that a fully breastfed infant would receive a pretomanid dosage of 1.02 mcg/kg daily with a standard maternal dose of 200 mg daily.[1] However, the authors used a nonstandard milk volume in their calculation. Using the standard 150 mL/kg daily, the estimated infant dosage would be 0.83 mcg/kg daily.
Infant Levels. Relevant published information was not found as of the revision date.
“No published information” means the studies do not exist yet — not that Pretomanid 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.
