Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

On last update relevant published data concerning breastfeeding were not found.

Pharmacokinetic data suggest that excretion into breast milk would be significant. However, it is considered safe for treatment of parasite infections like Amebiasis in children, with a dosage for children weighing over 5 kg that has been established by the manufacturer.

It is a medication included in a same group and similar properties of Metronidazole.


We do not have alternatives for Secnidazole 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.
