Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

A broad-spectrum anthelmintic and antiprotozoal. Indicated in the treatment of systemic helminthiases: echinococcosis and neurocysticercosis (Taenia solium), as well as in intestinal infestations by pinworms, ascarids and other nematodes. Oral administration in single or daily doses over three days.

Its low intestinal absorption (Pérez 2009) explains why it is excreted in breastmilk in clinically insignificant amounts (Abdel 2009) and no problems have been reported in infants whose mothers were taking it. (Dhonukshe 2005)

Its very low oral bioavailability prevents transfer to infant plasma via breastmilk, except in premature babies and the immediate neonatal period when there may be increased intestinal permeability.

Taking albendazole does not alter milk production. (Mofid 2021)

It has very low toxicity (Pérez 2009). It has been used in children under one year of age. (Tianyi 2018, Echazú 2017)

Expert authors and the WHO consider its use during breastfeeding to be probably safe (and even indicated to prevent iron deficiency anemia and maternal malnutrition). (Hale 2017 p34, Mofid 2017, Schaefer 2007 p670, Mahadevan 2006, Allen 2002)

We do not have alternatives for Albendazole 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.
