Since the last update we have not found any published data on its excretion in breast milk.

Its pharmacokinetic characteristics (lelevated molecular weight and very high plasma protein binding: EMA 2019, AEMPS 2019, Smolders 2019) make it very unlikely its excretion into breast milk in significant amounts

Possible side effects are rare and mild.

  • Maternal Hepatitis C Infection (Safe substance and/or breastfeeding is the best option.)
  • Pibrentasvir (Fairly safe. Mild or unlikely adverse effects. Compatible under certain circumstances. Follow-up recommended. Read Commentary.)

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.
