Possible Effects on Lactation

One case of elevated serum prolactin and galactorrhea was reported in a 21-year-old man. When omeprazole was substituted for lansoprazole, the serum prolactin decreased to the normal range and galactorrhea ceased.[1]

A 13-year-old girl with a recent history of bilateral galactorrhea and hyperprolactinemia from omeprazole and domperidone on separate occasions was given lansoprazole to prevent gastrointestinal irritation following intravenous diclofenac for a severe headache. After 3 days of lansoprazole therapy, she again developed galactorrhea and an elevated serum prolactin that returned to normal a week after discontinuing lansoprazole.[2]
