- Cariprazine 1.5 mg PO on Days 1 and 3 (no dose on Day 2)
- From Day 4 onward, administer 1.5 mg PO qDay, then increased to a maximum of 3 mg/day
- When CYP3A4 inhibitor is discontinued, cariprazine dosage may need to be increased
Coadministration with CYP3A4 inducers
- Coadministration has not been evaluated and is not recommended because the net effect on active drug and metabolites is unclear
Hepatic impairment
- Mild-to-moderate (Child-Pugh score 5-9): No dosage adjustment required

- Closely monitor all antidepressant-treated patients for clinical worsening, and for the emergence of suicidal thoughts and behaviors
- Safety and effectiveness of cariprazine has not been established in pediatric patients
Contraindications
Hypersensitivity to cariprazine
Cautions
Antipsychotic drugs increase the all-cause risk of death in elderly patients with dementia-related psychosis; a higher incidence of stroke and TIA, including fatal stroke, was also observed (see Black Box Warnings)
Hypersensitivity reactions reported ranging fom rash, pruritus, urticaria, and events suggestive of angioedema (eg, swollen, tongue, lip swelling, face edema, pharyngeal edema, facial swelling)
Neuroleptic malignant syndrome reported; monitor for hyperpyrexia, muscle rigidity, delirium, and autonomic instability; other signs include increased CPK, myoglobinuria (rhabdomyolysis), and acute renal failure; if NMS is suspected, immediately discontinue treatment
Tardive dyskinesia, a potentially irreversible, involuntary, dyskinetic movement syndrome, may develop in patients treated with antipsychotics
Adverse effects may first appear several weeks after initiating treatment, as drug and metabolite levels accumulate; monitor for extrapyramidal symptoms or akathisia
Leukopenia and neutropenia reported; agranulocytosis (including fatal cases) reported with other atypical antipsychotics; discontinue cariprazine in patients with absolute neutrophil count <1000/mm³ and follow WBC until recovery
May cause orthostatic hypotension and syncope; caution in patients vulnerable to hypotension (eg, elderly, dehydration, hypovolemia, concomitant antihypertensive drugs, cardiovascular or cerebrovascular disease)
May cause seizures; risk is greatest with history of seizures or conditions that lower seizure threshold
Body temperature dysregulation reported; may disrupt ability to reduce core body temperature; caution with strenuous exercise, exposure to extreme heat, dehydration, and coadministration with anticholinergic medications
Esophageal dysmotility and aspiration reported with antipsychotic drug use
May cause somnolence with potential to impair judgment or thinking; may cause postural hypotension, motor and sensory instability, which may lead to falls and, consequently, fractures or other injuries; for patients with diseases, conditions, or medications that could exacerbate these effects, complete fall risk assessments when initiating antipsychotic treatment and recurrently for patients on long-term antipsychotic therapy
Drug interactions overview
- Coadministration with a strong CYP3A4 inhibitor increases the exposures of cariprazine and its major active metabolite, didesmethylcariprazine (DDCAR), compared to use of cariprazine alone (see Dosage Modifications)
- Effect of CYP3A4 inducers on the exposure of cariprazine has not been evaluated, and net effect is unclear
Metabolic changes
- Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, reported; assess fasting plasma glucose before or soon after initiation of antipsychotic medication, and monitor periodically
- Lipids alteration has occurred; obtain a fasting lipid profile at baseline and monitor periodically during treatment before or soon after initiation of antipsychotic medication
- Weight gain observed; monitor weight at baseline and frequently thereafter
Suicidal thoughts or behaviors
- Pooled analyses of placebo-controlled trials of antidepressive drugs showed an increased risk of suicidal thoughts or behavior in patients aged ≤24 yr taking these drugs for any indication; monitor for emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior
- Inform patients, their caregivers, and families of the increase the risk of suicidal thoughts and behavior; advise to be alert for the emergence or worsening of signs and symptoms
Pregnancy
Pregnancy
Neonates exposed to antipsychotic drugs during third trimester of pregnancy are at risk for extrapyramidal symptoms or withdrawal symptoms after delivery; these complications vary in severity, with some being self-limited and others requiring ICU support and prolonged hospitalization
Pregnancy exposure registry
- Report exposure during pregnancy to the National Pregnancy Registry for Atypical Antipsychotics 1-866-961-2388 OR, http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/
Animal data
- Administration in pregnant rats during organogenesis at doses 0.2 to 3.5 times maximum recommended human dose caused fetal developmental toxicity at all doses, including reduced body weight, decreased male anogenital distance, and skeletal malformations of bent limb bones, scapula, and humerus
- Decreased postnatal survival, birth weight, and post-weaning body weight was also observed
Lactation
Unknown if distributed in human breast milk
Present in rat milk
Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for the drug, and any potential adverse effects on the breastfed infant from the drug or from the underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Precise mechanism by which cariprazine works for schizophrenia or bipolar disorder is unknown
Efficacy could be mediated through a combination of partial agonist activity at central dopamine (D2) and serotonin 5-HT1A receptors
Forms 2 major metabolites, desmethyl cariprazine (DCAR) and didesmethyl cariprazine (DDCAR), that have in vitro receptor binding profiles similar to the parent drug
Absorption
Peak plasma time: 3-6 hr (cariprazine)
Mean concentrations of DCAR and DDCAR are ~30% and 400%, respectively, of cariprazine concentrations by the end of 12-week treatment
Distribution
Protein bound: 91-97% (parent drug and metabolites)
Metabolism
Active metabolites: Desmethyl cariprazine (DCAR) and didesmethyl cariprazine (DDCAR) are pharmacologically equipotent to cariprazine
Extensively metabolized by CYP3A4 to DCAR and DDCAR
Metabolized to a lesser extent by CYP2D6 to DCAR and DDCAR
DDCAR is metabolized by CYP3A4 to a hydroxylated metabolite
Elimination
Half-life: 2-4 days (cariprazine); 1-3 weeks (DDCAR)
Excretion, cariprazine 12.5 mg/day: Urine (21%); [1.2% unchanged]
Administration
Instructions
Take orally with or without food
Discontinuation
- Decline in plasma concentrations of active drug and metabolites may not be immediately reflected in patients’ clinical symptoms
- Plasma concentration declines by 50% in ~1 week
- There are no systematically collected data to address switching patients from cariprazine to other antipsychotics or concomitant administration with other antipsychotics
Storage
Store at controlled room temperature (20-25ºC [68-77ºF]); excursions permitted between 15-30ºC (59-86ºF)
Protect 3- and 4.5-mg capsules from light to prevent potential color fading
