Ursodeoxycholic Acid

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Biliary salt that appears in low amount in the serum because it is absorbed to the portal circulation and completely excreted into biliary duct.

Excreted into breast milk in non-significant amount with no side-effects being observed among infants of treated mothers.

Medication that has been used for treatment of newborns and older infants.


We do not have alternatives for Ursodeoxycholic Acid 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.
