Is Ziprasidone safe while breastfeeding?
Here is what NIH LactMed, the U.S. National Library of Medicine's authority on medicines and breastfeeding, reports about Ziprasidone. This is a summary of that source — not our own verdict.
Effects on the breastfed infant
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 ] Patients enlisted in the National Pregnancy Registry for Atypical Antipsychotics who were taking a second-generation antipsychotic drug while breastfeeding (n = 576) were compared to control breastfeeding patients who were not treated with a second-generation antipsychotic (n = 818). Of the patients who were taking a second-generation antipsychotic drug, 60.4% were on more than one psychotropic. A review of the pediatric medical records, no adverse effects were noted among infants exposed or not exposed to second-generation antipsychotic monotherapy or to polytherapy.[ 4 ] The number of women taking ziprasidone was not reported.
Effects on milk supply
Prolactin elevation has occurred during ziprasidone treatment,[ 5 - 10 ] and galactorrhea has been reported, often in adolescents.[ 7 - 12 ] However, prolactin elevation might be more transient and less severe than with phenothiazines.[ 13 - 15 ] The prolactin level in a mother with established lactation may not affect her ability to breastfeed. Patients enlisted in the National Pregnancy Registry for Atypical Antipsychotics who were taking a second-generation antipsychotic drug while breastfeeding (n = 576) were compared to control breastfeeding patients who had primarily diagnoses of major depressive disorder and anxiety disorders, most often treated with SSRI or SNRI antidepressants, but not with a second-generation antipsychotic (n = 818). Among women on a second-generation antipsychotic, 60.4% were on more than one psychotropic compared with 24.4% among women in the control group. Of the women on a second-generation antipsychotic, 59.3% reported ever breastfeeding compared to 88.2% of women in the control group. At 3 months postpartum, 23% of women on a second-generation antipsychotic were exclusively breastfeeding compared to 47% of women in the control group.[ 4 ] The number of women taking ziprasidone was not reported.
Levels in milk
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.
