Answer by DrLact: About PA-94 usage in lactation

Limited information from an old study indicates that maternal doses of PA-94 of 1 gram daily produce moderate levels in milk. If PA-94 is required by the mother, it is not a reason to discontinue breastfeeding, especially if the infant is older than 2 months. Exclusively breastfed infants should be monitored if this drug is used during lactation, possibly including measurement of serum levels to rule out toxicity if there is a concern.
