Long-Term Effects

  • See “What Are Side Effects Associated with Using Lumateperone?”


  • Geriatric patients with dementia-related psychosis who are treated with antipsychotic drugs are at increased risk of death
  • Geriatric patients with dementia who were treated with antipsychotics had a higher incidence of stroke and transient ischemic attacks, including fatal stroke
  • Monitor all antidepressant-treated patients for any indication of clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of drug therapy, and at times of dosage changes; counsel family members or caregivers of patients to monitor for changes in behavior and to alert the healthcare provider; consider changing the therapeutic regimen, including possibly discontinuing therapy, in patients whose depression is persistently worse, or who are experiencing suicidal thoughts or behaviors
  • Neuroleptic malignant syndrome (NMS), a potentially fatal symptom complex, is reported with the administration of antipsychotic drugs; if NMS is suspected, immediately discontinue lumateperone and provide intensive symptomatic treatment and monitoring
  • Tardive dyskinesia, a syndrome consisting of potentially irreversible, involuntary, dyskinetic movements, may develop in patients treated with antipsychotic drugs; risk appears to be highest among elderly individuals, especially women, but it is not possible to predict which patients are likely to develop the syndrome
  • May cause metabolic changes, including hyperglycemia, diabetes mellitus, dyslipidemia, and weight gain
  • Leukopenia and neutropenia were reported with antipsychotic agents, including lumateperone; agranulocytosis was reported with other agents in the class
  • May cause orthostatic hypotension and syncope; risk is greatest during initial dose administration
  • Antipsychotics, including lumateperone, may cause somnolence, postural hypotension, and motor and sensory instability, which may lead to falls and, consequently, fractures and other injuries
  • May cause seizures; risk is greatest with a history of seizures or with conditions that lower seizure threshold
  • It May cause somnolence and has the potential to impair judgment, thinking, and motor skills
  • May disrupt the body’s ability to reduce core body temperature; strenuous exercise, exposure to extreme heat, dehydration, and anticholinergic medications may contribute to an elevated core body temperature
  • Esophageal dysmotility and aspiration reported with antipsychotic drug use

    • CYP3A4 inhibitors
      • Strong inhibitors: Reduce lumateperone dose to 10.5 mg/day
