Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Used as systemic treatment of onchocercosis, strongyloidiasis, filariasis and scabies (Pérez 2009, Prescrire 2002). Oral administration. Topically it is used in the treatment of pediculosis capitis. Used experimentally in the treatment of the COVID-19 coronavirus. (Vallejos 2020)

Its pharmacokinetic data (high molecular weight and high protein binding) explain the small excretion in breast milk, without clinical relevance for the infant. (Rodari 2020, Ogbuokiri 1993)

No problems have been observed in infants whose mothers were taking it. (Porto 2003, Ogbuokiri 1994 y 1993)

Expert authors consider the use of this medication safe during breastfeeding. (Anderson 2020)

We do not have alternatives for Ивермектин 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.
