Drug Levels and Effects
Summary of Use during Lactation
No information is available on the clinical use of posaconazole during breastfeeding. Because posaconazole is more than 98% bound to plasma proteins, the amount in milk is likely to be low. However, there is no published experience with posaconazole during breastfeeding, so an alternate drug may be preferred, especially while nursing a newborn or preterm infant.
