Sodium Chloride

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Sodium chloride or common salt is used in oral or intravenous solutions for hydration, eye and bladder irrigations, skin or wound cleansing, as a diluent for parenteral administration of other drugs, as nose drops and nasal irrigations, in rinse for oral hygiene and in nutritional products as a source of electrolytes and water.

Sodium is a fundamental element in the body. Breast milk contains sodium (15 mg/100 ml= 6.5 mEq/L) in lower concentration than in blood plasma (320 mg/100 ml = 139 mEq/L). (Lawrence 2016 p 120)

Daily intake should not exceed 2g sodium = 5g salt. (Mind 2021, Hall 2010)

Excess maternal sodium intake does not result in elevated levels of sodium in milk. Sodium is excreted in milk by a controlled mechanism independent of maternal serum levels. (Lawrence 2016 p354, Yereman 1987)

We do not have alternatives for Sodium Chloride 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.

José María Paricio, founder of e-lactancia.
