Cautions

Pregnancy and Lactation

  • There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, during pregnancy; healthcare providers are encouraged to register patients by contacting the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or online at http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry
  • Neonates exposed to antipsychotic drugs, during the third trimester are at risk for extrapyramidal and/or withdrawal symptoms, following delivery; overall available data from published epidemiologic studies of pregnant women have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes; there are risks to mother associated with untreated schizophrenia or bipolar I disorder and with exposure to antipsychotics, during pregnancy
  • There is a risk to the mother from untreated schizophrenia or bipolar I disorder, including increased risk of relapse, hospitalization, and suicide
  • Schizophrenia and bipolar I disorder are associated with increased adverse perinatal outcomes, including preterm birth; it is not known if this is a direct result of illness or other comorbid factors
  • Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder have been reported in neonates exposed to the drug, during the third trimester of pregnancy; these symptoms have varied in severity; monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately; some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. 

Lactation

  • Limited data from a published case report indicate the presence of drugs in human milk; although there are no reports of adverse effects on a breastfed infant exposed to the drug via breast milk, there are reports of excess sedation, irritability, poor feeding, and extrapyramidal symptoms (tremors and abnormal muscle movements) in infants exposed to other atypical antipsychotics through breast milk
  • There is no information on the effects of drugs on milk production; developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for drug and any potential adverse effects on the breastfed child from the drug or mother’s underlying condition
  • Infants exposed to the drug should be monitored for excess sedation, irritability, poor feeding, and extrapyramidal symptoms (tremors and abnormal muscle movements).
