Drug Levels and Effects

Summary of Use during Lactation

A safety scoring system finds ziprasidone possible to use cautiously during breastfeeding.[1] Because there is little published experience with ziprasidone during breastfeeding, other antipsychotic agents are preferred, especially while nursing a newborn or preterm infant.

Drug Levels

Maternal Levels. In one woman, ziprasidone was started at 9 days postpartum (dosage not stated, but presumably at a low dose and titrated upward). Serum and milk concentrations were obtained 10 minutes before the morning dose every day for 16 days. By day 7 of therapy, the patient was taking 80 mg of ziprasidone twice daily. Ziprasidone was not detectable in milk until day 10 of therapy when the milk concentration was 11 mcg/L; thereafter, the milk concentrations were not quantifiable (<10 mcg/L).[2]

Infant Levels. Relevant published information was not found as of the revision date.

Effects in Breastfed Infants

A woman took ziprasidone 40 mg and citalopram 60 mg daily throughout pregnancy and postpartum. She breastfed extensively, except for occasional formula feedings by others. At 6 months of age, a pediatrician found the infant to be healthy with normal growth and development.[3]

Effects on Lactation and Breastmilk

Prolactin elevation has occurred during ziprasidone treatment,[4-9] and galactorrhea has been reported, often in adolescents.[6-11] However, prolactin elevation might be more transient and less severe than with phenothiazines.[12-14] The prolactin level in a mother with established lactation may not affect her ability to breastfeed.
