Tetracaine use while Breastfeeding

Summary of Use during Lactation

No information is available on the use of tetracaine during breastfeeding. Based on the low excretion of other local anesthetics into breastmilk, a single dose of injected tetracaine 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 tetracaine 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]
