Cariprazine (brand Vraylar) is an second-generation antipsychotic (SGA) that preferentially targets dopamine D3 receptors, supporting efficacy across schizophrenia and bipolar disorder mood states. This profile emphasizes its role in schizophrenia, bipolar I mania/mixed episodes, bipolar depression, and adjunctive major depressive disorder (MDD; clinical depression) as add-on therapy to antidepressants.

- Cariprazine mechanism of action combines D3/D2 partial agonism with 5-HT1A partial agonism and 5-HT2A antagonism, making it a close comparator to aripiprazole and brexpiprazole while offering stronger D3 affinity.
- Clinicians leverage cariprazine for negative-symptom improvement and bipolar depression coverage. Long-lived metabolites demand slow titration and careful monitoring for akathisia and GI upset; metabolic impact is moderate.
- The compare view, the cariprazine evidence feed, and the cariprazine print page can support shared decision-making and counseling; the schizophrenia hub and bipolar disorder hub link to broader care pathways.

- Bipolar I manic/mixed episodes (adults) (FDA 2015)
- Bipolar I depression (adults) (FDA 2019)
Dosing & Formulations
Oral capsules (cariprazine hydrochloride / cariprazine HCl): 1.5 mg, 3 mg, 4.5 mg, 6 mg; blister and bottle packaging. Schizophrenia: start 1.5 mg once daily; increase to 3 mg on day 2; adjust by 1.5–3 mg increments at ≥2-week intervals to 1.5–6 mg/day (max 6 mg).
Read more
- Bipolar I mania/mixed: initiate 1.5 mg once daily, increase to 3 mg on day 2, then titrate by 1.5 mg increments up to 6 mg/day.
- Bipolar I depression: 1.5 mg once daily for at least 14 days; may increase to 3 mg/day based on response.
- Adjunctive major depressive disorder (clinical depression): start 1.5 mg once daily with an antidepressant; may increase to 3 mg/day (max 3 mg/day).
- Label recommends halving the dose with strong CYP3A4 inhibitors; coadministration with strong CYP3A4 inducers is generally avoided; not recommended in severe hepatic impairment.
- Long effective half-life (up to 1–3 weeks for metabolites) means dose changes or missed doses manifest gradually; waiting several weeks before further adjustments is common.
Monitoring & Risks
Boxed warning: Increased mortality in elderly patients with dementia-related psychosis (antipsychotic class warning). Boxed warning: Suicidal thoughts and behaviors in children, adolescents, and young adults treated with antidepressants (applies to adjunctive MDD indication).
Read more
- Akathisia: Occurs in up to 20% depending on dose; most frequent cause of discontinuation.
- Extrapyramidal symptoms (EPS): Overall 6–10%, predominantly akathisia and tremor.
- Nausea: Approximately 10% of patients.
- Somnolence: Around 10% across indications.
Drug Interactions
Strong CYP3A4 inhibitors (ketoconazole, clarithromycin) increase exposure; label recommends reducing cariprazine dose by half and monitoring for akathisia or sedation. Strong CYP3A4 inducers (rifampin, carbamazepine, St. John’s wort) substantially lower exposure; coadministration is generally avoided.

- Moderate CYP3A4 inhibitors often warrant slower titration and closer monitoring.
- Additive CNS depression with alcohol, benzodiazepines, or opioids.
- May blunt efficacy of dopamine agonists (e.g., levodopa); this combination is often avoided when dopaminergic therapy is needed.
Practice Notes
Long-lived metabolites mean clinical response to dose changes can be delayed; allowing several weeks before adjusting again is common. Patients and caregivers can be advised on early akathisia; clinicians often manage it with dose adjustments, beta-blockers, or benzodiazepines.

- Low impact on QTc, but a baseline ECG is often considered in patients with cardiac risk or polypharmacy.
- Once-daily dosing at a consistent time (with or without food) helps maintain steady exposure.
- Metabolic monitoring typically includes baseline, 12 weeks, then annually.
- Comparing dopamine partial agonists via the compare view can help tailor negative-symptom or bipolar depression strategies.
