The limited information available suggests that, at the doses normally used, this substance reaches a low concentration in breast milk, so it is not expected to cause adverse effects on the baby. Using data from a single observation, could be concluded that the infant would receive 0.14% of the dose given to the mother.
Given that is risky to generalize data from a single patient, it is recommended to replace pantoprazole with an alternative drug best documented.
Warning of the manufacturer:
No information on the excretion of pantoprazole in breast milk. Pantoprazole should be used only if the benefit to the mother is considered greater than the potential risk to the fetus or infant.
