Very Low Risk for breastfeeding

Safe. Compatible.
Minimal risk for breastfeeding and infant.

R Isomer of Lansoprazole with similar pharmacokinetics.

At latest update, relevant information on excretion into breast milk was not found.

Due to a high serum-protein-binding capacity, excretion of Lansoprazole into breast milk is non-significant.

Since it's neutralized by the acid pH of stomach, capsules with enteric coated granules are used. Because of this, it is thought that the small quantity of Lansoprazole that may reach the breast milk would be neutralized by infant's stomach. In addition, absorption is greatly decreased by the presence of food.

Both Omeprazole and Pantoprazole pertain to the same chemical group with similar pharmacokinetics that are excreted in non-significant amount into the breast milk.

Medication that has been used for treatment of newborn and premature infants.

Hyperprolactinemia and galactorrhea have been reported by the use of such medication, though some authors have failed to show the same findings.
