Drug Levels and Effects:

Summary of Use during Lactation:

Because there is no published experience with ziprasidone during breastfeeding, other antipsychotic agents are preferred.

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).[1]

Infant Levels.

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

Effects in Breastfed Infants:

A woman took ziprasidone 40 mg andcitalopram60 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.[2]

Possible Effects on Lactation:

Prolactin elevation and galactorrhea has occurred during ziprasidone treatment.[3][4][5][6] However, prolactin elevation might be more transient and less severe than with phenothiazines.[7][8][9] The prolactin level in a mother with established lactation may not affect her ability to breastfeed.
