Effects on Lactation and Breastmilk

A retrospective claims database study in the United States found that users of proton pump inhibitors had an increased risk of gynecomastia.[1]

The Spanish pharmacovigilance system found one case of a 90-year-old man who developed gynecomastia associated with rabeprazole reported during the time period of 1982 to 2006. The reaction occurred after 32 days of therapy and resolved after discontinuation of the drug.[2]
