Sodium Phenylbutyrate Levels and Effects while Breastfeeding

Summary of Use during Lactation

No information is available on the clinical use of sodium phenylbutyrate or the combination of sodium phenylbutyrate and taurursodiol during breastfeeding. Both sodium phenylbutyrate and taurursodiol are highly protein bound and therefore unlikely to enter milk in clinically important amounts. If sodium phenylbutyrate with or without taurursodiol is required by the mother, it is not a reason to discontinue breastfeeding. Until more data become available, these products should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant. Monitoring the breastfed infant for neurotoxicity (excessive sedation, vomiting) during maternal therapy may be advisable.
