Hepatitis C virus NS5A protein inhibitor.
Used in combination with glecaprevir in the treatment of chronic hepatitis C virus infection.
Oral administration in a daily dose for 8 to 16 weeks.

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.

See below the information of these related products:

  • Glecaprevir (Possibly safe. Probably compatible. Mild risk possible. Follow up recommended. Read the Comment.)
  • Maternal Hepatitis C Infection ( Safe. Compatible. Minimal risk for breastfeeding and infant.)

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.
