Fluphenazine Levels and Effects while Breastfeeding
Summary of Use during Lactation
There is no published experience with fluphenazine during breastfeeding. Very limited long-term follow-up data indicate no adverse developmental effects when other phenothiazines are used alone. Because of the lack of published experience with fluphenazine during breastfeeding, other antipsychotic agents may be preferred, especially wile nursing an newborn or preterm infant. Monitor the infant for drowsiness and developmental milestones, especially if other antipsychotics are used concurrently.

Effects on Lactation and Breastmilk
Phenothiazines cause galactorrhea in 26 to 40% of female patients. Hyperprolactinemia appears to be the cause of the galactorrhea. The hyperprolactinemia is caused by the drug's dopamine-blocking action in the tuberoinfundibular pathway.
Fluphenazine elevates serum prolactin similar to other phenothiazines and has caused galactorrhea. The elevation is related to serum levels and lasts 2 to 4 weeks with the depot injectable formulation. The maternal prolactin level in a mother with established lactation may not affect her ability to breastfeed.
