Pretomanid Levels and Effects while Breastfeeding

Summary of Use during Lactation

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.

Drug Levels

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.
