Sodium Fluoride

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Sodium fluoride is an essential element for the development of bones and teeth.  It is used in oral or topical administration to prevent dental caries and intravenously in parenteral nutrition solutions. 

Fluoride is found in breast milk and there is little relationship of its concentration with the amount of fluoride ingested by the mother, the passage of fluoride from plasma to milk being limited (Campus 2014, Sever 2007, Koparal 2000, Opinya 1991, Spak 1983), which protects infants from a possible excess of fluoride ingested by the mother. (Valdez 2019, Opinya 1991)

WHO essential drug list: compatible with breastfeeding in doses used as a nutritional supplement. (WHO-UNICEF 2002)


We do not have alternatives for Sodium Fluoride since it is relatively safe.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

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.
