Pregnancy-Lactation

Pregnancy There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, including risperidone, during pregnancy Healthcare professionals 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/ Infertility Based on the pharmacologic action of risperidone, treatment may result in an increase in serum prolactin levels, which may lead to reversible reduction in fertility in females of reproductive potential 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 reported in neonates who were exposed to antipsychotic drugs, including risperidone, during the third trimester of pregnancy; symptoms varied Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately Lactation Limited data from published literature reports the presence of risperidone and its metabolite, 9- hydroxyrisperidone, in human breast milk at relative infant dose ranging between 2.3 and 4.7% of the maternal weight-adjusted dosage Reports of sedation, failure to thrive, jitteriness, and extrapyramidal symptoms (tremors and abnormal muscle movements) in breastfed infants exposed to risperidone Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for the drug, and any potential adverse effects on the breastfed infant from the drug or from the underlying maternal condition

Potentially Fatal: Risperidone may enhance the hypotensive effect of certain antihypertensives.

Mechanism of Action

Risperidone is an atypical antipsychotic. Its activity is mediated through a combination of dopamine (D2) and serotonin (5-HT2) receptor antagonism. It also exhibits affinity to adrenergic (alpha1 and alpha2) and histamine (H1) receptors. It is less likely to cause extrapyramidal effects than conventional antipsychotics.
