Not risky for breastfeeding or infant.
Strong-acting topical anesthetic used in local dermatological, ophthalmologic, oropharyngeal and urological anesthesia. Its use in epidural anesthesia is very rare.
Since the last update we have not found any published data on its excretion in breast milk.
Topical anesthetics (dermatological and stomatological preparations) when well applied have very low systemic absorption so that levels in plasma and, therefore, in breastmilk are zero or insignificant. Absorption is possibly greater if applied to inflamed skin.
The low cutaneous absorption, the rapid hydrolysis of tetracaine in the plasma and its rapid elimination (AEMPS 2014, Galderma 2012) contribute to the fact that after the application of cutaneous topical tetracaine the plasma levels are undetectable or very low (AEMPS 2014, Galderma 2012, Ogden 2008, Terndrup 1992, Mazumdar 1991).
Therefore, it can be considered compatible with breastfeeding (Briggs 2017, Galderma 2012, Schaefer 2007 p632).
It should not be applied over large areas or for prolonged periods to minimize systemic absorption.
Do not apply to the breast to prevent the infant from ingesting it; if necessary, apply after a feed and clean thoroughly with water before the next one.
We do not have alternatives for Тетракаин since it is relatively safe.
Suggestions made at e-lactancia are done by APILAM´s pediatricians and pharmacists, and are based on updated scientific publications.
It is not intended to replace the relationship you have with your doctor but to compound it.
Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.
Thank you for helping to protect and promote breastfeeding.
