At latest update, relevant published data on excretion into breast milk were not found. Topical anesthetics (intended for dermatological or oral use) when properly used, show limited systemic absorption which is practically nil, with nil or non-significant systemic levels in the plasma and breast milk. Benzocaine may induce appearance of methemoglobinemia and systemic toxicity if absorbed. Avoid use on the breast, otherwise, in case of use on the nipple, let it be done after a feed and wipe it out by thoroughly washing with water before the next feed. Do not apply creams, gels and other products that would contain paraffin (mineral oil) to avoid absorption by the infant since it is a hydrocarbon-derived substance.
