Benzocaine Levels and Effects while Breastfeeding

Summary of Use during Lactation

Topical benzocaine has not been studied during breastfeeding, but is unlikely to affect her breastfed infant if it is applied away from the breast. Benzocaine should not be applied to the breast or nipple, because the infant may ingest the drug during nursing and it has been associated with severe methemoglobinemia in children under 2 years of age.[1]
