Chenodeoxycholic Acid (CDCA)

Low Risk

Possibly safe. Probably compatible. Mild risk possible. Follow up recommended. Read the Comment.

It is a natural bile acid present in human bile. It suppresses the hepatic synthesis and secretion of cholesterol and inhibits the intestinal absorption of cholesterol. It is an epimer of ursodeoxycholic acid. It is used for the treatment of primary biliary cirrhosis and the dissolution of gallstones. Oral administration one to three times a day.

At the date of the last update we did not find any published data on its excretion in breast milk, but since it is an epimer of ursodeoxycholic acid, compatible with breastfeeding, similar pharmacokinetics are to be expected.

It is a bile salt that partially epimerizes to ursodeoxycholic acid that appears in very low levels in the serum (and breast milk) because it is delivered to portal circulation and completely excreted by the liver through the bile duct.

It has been used as a dietary supplement in neonates and children with inborn errors of bile acid synthesis.

Bile salts are found in breast milk in small amounts (Forsyth 1983). Altered bile acid ratios in breast milk have been linked to prolonged jaundice from breastfeeding. (Forsyth 1990)

The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

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.
