Hydrogen Peroxide

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

An oxidizing agent which is used as a disinfectant, antiseptic, deodorant and for hair bleaching.

At latest update relevant published data were not found on excretion into breast milk.

It is found naturally in breastmilk (Al-Kerwi 2005) and can be produced by certain lactobacilli. (Martin 2006).

Because of the small dose used and poor absorption into plasma of most topical dermatologic preparations, it is unlikely a significant excretion into breast milk.

Do not apply it on the breast to prevent ingestion by the infant; otherwise, do it just after a meal and clean the nipple thoroughly with water before the next feed.


We do not have alternatives for Hydrogen Peroxide 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
