Very Low Risk for breastfeeding

Safe. Compatible.
Not risky for breastfeeding or infant.

Anesthetic drugs for topical use, both dermatological and odontological, have almost nil absorption when properly used. Do not apply on breast. Otherwise, do it after having nursed, and cleanse it thoroughly with water before next feeding.


We do not have alternatives for Tetracaine 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.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

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.

José María Paricio, founder of e-lactancia.
