Possible Effects on Lactation:


Galactorrhea has been reported with prochlorperazine.[1] Hyperprolactinemia appears to be the cause of the galactorrhea.[2][3][4] The hyperprolactinemia is caused by the drug's dopamine-blocking action in the tuberoinfundibular pathway.[5] The prolactin level in a mother with established lactation may not affect her ability to breastfeed.
