Oral route (Capsule)

Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Cariprazine is not approved for the treatment of patients with dementia-related psychosis. Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric and young adult patients in short-term studies. Closely monitor all antidepressant-treated patients for clinical worsening, and for the emergence of suicidal thoughts and behaviors. The safety and effectiveness of cariprazine have not been established in pediatric patients.

The most frequently reported adverse effects were extrapyramidal symptoms, akathisia, nausea, vomiting, somnolence, and restlessness.[Ref]

Nervous system

During 6-week schizophrenia placebo-controlled trials, 17% of patients reported extrapyramidal symptoms, excluding akathisia and restlessness in the treatment group. This led to study discontinuation in 0.3% of patients. Akathisia occurred in 11% of patients, leading to study discontinuation of 0.5%.

In 3-week bipolar mania placebo-controlled trials, 28% of patients given this drug experienced extrapyramidal symptoms, excluding akathisia and restlessness. This led to study discontinuation in 1% of patients. Akathisia occurred in 20% of patients, leading to study discontinuation of 2%.[Ref]

Hyperglycemia/Diabetes Mellitus: In long-term, open label studies in patients with schizophrenia or bipolar disorder, 4% of patients with normal baseline hemoglobin A1c developed elevated levels (HbA1c 6.5% or higher). In short-term trials, the number of patients with shifts from normal fasting glucose (less than 100 mg/dL) to high (greater than 126 mg/dL) and borderline (100 to less than 126 mg/dL) levels were similar to placebo-treated patients.

Dyslipidemia: In the 3-week placebo controlled bipolar mania and 6-week placebo controlled schizophrenia trials, the shifts in fasting total cholesterol, LDL, HDL, and triglycerides were similar in treatment and placebo groups.
