Safe substance and/or breastfeeding is the best option.

Antibiótico derivado de la rifamicina, no aborbible, utilizado por vía oral para tratar determinadas diarreas y afecciones intestinales.

A fecha de última actualización no encontramos datos publicados en relación con la lactancia pero su falta casi absoluta de absorción intestinal (< 1%) y su elevado peso molecular hacen muy improbable su paso a leche. Por otra parte sus posibles efectos secundarios son leves y casi limitados a molestias abdominales.


We do not have alternatives for リファキシミン 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.
