Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Pharmacokinetic data (high volume of distribution and molecular weight) would explain the minimal excretion into breast milk mentioned in two older reports.

Due to a poor oral bioavailability, appearance in the infant's plasma from ingested milk is regarded as nil or scanty, except in premature infants or during the immediate neonatal period who may show an increased intestinal absorption.


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

Suggestions made at e-lactancia are done by APILAM team, 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.
