Special Population Considerations

Pregnancy

  • There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, including INVEGA TRINZA, during pregnancy
  • Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery

Nursing Mothers

  • It is not known whether INVEGA TRINZA is excreted in human breast milk

Pediatric Use

  • Safety and effectiveness of INVEGA TRINZA in patients less than 18 years of age have not been established
  • Use of INVEGA TRINZA is not recommended in pediatric patients because of the potential longer duration of an adverse event compared to shorter-acting products

Geriatric Use

  • Clinical studies of INVEGA TRINZA did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects
  • This drug is known to be substantially excreted by the kidney and clearance is decreased in patients with renal impairment
