Prilocaine

No information is available on the use of prilocaine during breastfeeding. Based on the low excretion of other local anesthetics into breastmilk, a single dose of prilocaine injected during breastfeeding, such as for a dental procedure, is unlikely to adversely affect the breastfed infant. However, an alternate drug may be preferred, especially while nursing a newborn or preterm infant. Topical application of prilocaine to the mother is unlikely to affect her breastfed infant if it is applied away from the breast. Only water-miscible cream or gel products should be applied to the breast because ointments may expose the infant to high levels of mineral paraffins via licking.[1]
