BOXED WARNING: "Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Aripiprazole tablets are not approved for the treatment of patients with dementia-related psychosis." The boxed warning also covers increased suicidality risk: "Antidepressants increased the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term studies." Contraindicated in patients with a history of hypersensitivity, which has "ranged from pruritus/urticaria to anaphylaxis." Other key warnings include cerebrovascular adverse events (stroke, TIA), neuroleptic malignant syndrome, tardive dyskinesia, metabolic changes (hyperglycemia, dyslipidemia, weight gain), orthostatic hypotension, and seizures.
Aripiprazole tablets are indicated for "schizophrenia" and "treatment of Tourette's Disorder," among other approved uses (including bipolar disorder and adjunctive treatment of MDD per the full label). Adult schizophrenia dosing typically starts at "10 or 15 mg/day administered on a once-a-day schedule."
