ailable data from published epidemiologic studies of pregnant women exposed to risperidone have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes (see DATA). There are risks to the mother associated with untreated schizophrenia and with exposure to antipsychotics, including PERSERIS, during pregnancy (see CLINICAL CONSIDERATIONS).
Oral administration of risperidone to pregnant mice caused cleft palate at doses 3 to 4 times the maximum recommended human dose (MRHD) of 16 mg/day with maternal toxicity observed at 4 times the MRHD based on mg/m2 body surface area. Risperidone was not teratogenic in rats or rabbits at doses up to 6 times the MRHD based on mg/m2 body surface area. Increased stillbirths and decreased birth weight occurred after oral risperidone administration to pregnant rats at 1.5 times the MRHD based on mg/m2 body surface area. Learning was impaired in offspring of rats when the dams were dosed at 0.6 times the MRHD and offspring mortality increased at doses 0.1 to 3 times the MRHD based on mg/m2 body surface area.
Subcutaneous administration of the delivery system to pregnant rats and rabbits during the period of organogenesis caused developmental toxicity that included post-implantation loss, decreased number of live fetuses, decreased fetal weight and fetal malformations (external, skeletal, and visceral), at doses that are 52 (rat) and 43 (rabbit) times the delivery system amount present in 120 mg risperidone subcutaneous injectable suspension based on mg/m2 body surface area. These effects could be attributed to NMP an excipient in the delivery system based on information in the published literature (see DATA). Subcutaneous administration of the delivery system to pregnant and lactating rats had no effect on embryo/fetal and postnatal development at doses up to 17 times the delivery system amount present in 120 mg risperidone subcutaneous injectable suspension based on mg/m2 body surface area.
The estimated background risks of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Clinical Considerations
Disease-associated maternal and/or embryo/fetal risk
There is a risk to the mother from untreated schizophrenia, including increased risk of relapse, hospitalization, and suicide. Schizophrenia is associated with increased adverse perinatal outcomes, including preterm birth. It is not known if this is a direct result of the illness or other comorbid factors.
Fetal/neonatal adverse reactions
Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder have been reported in neonates who were exposed to antipsychotic drugs, including risperidone, 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.
