2 DOSAGE AND ADMINISTRATION
2.1 General Dosing Information VRAYLAR is given orally once daily and can be taken with or without food. Because of the long half-life of cariprazine and its active metabolites, changes in dose will not be fully reflected in plasma for several weeks Prescribers should monitor patients for adverse reactions and treatment response for several weeks after starting VRAYLAR and after each dosage change
The optimal dosing strategy for adjusting Vraylar (cariprazine) involves:
- Starting with a dose of 1.5 mg orally once daily
- Increasing the dose in 1.5 mg or 3 mg increments based on clinical response and tolerability
- Monitoring patients for adverse reactions and treatment response for several weeks after starting Vraylar and after each dosage change
- Considering dosage modifications when concomitantly taking strong or moderate CYP3A4 inhibitors, as outlined in Tables 1 and 2 1
- Key considerations:
- The long half-life of cariprazine and its active metabolites means that changes in dose will not be fully reflected in plasma for several weeks
- Dosages above 6 mg daily do not confer increased effectiveness sufficient to outweigh dose-related adverse reactions
- Concomitant use of Vraylar and a CYP3A4 inducer is not recommended
From the Research
Adjusting Vraylar (cariprazine) should always be done under the supervision of a healthcare provider who prescribed it, with a recommended dose range of 1.5-6 mg/d for the treatment of schizophrenia and acute treatment of manic or mixed episodes associated with bipolar I disorder, as supported by the most recent study 2. The optimal dosing strategy for adjusting Vraylar (cariprazine) involves gradual dosage adjustments, starting at 1.5 mg once daily and potentially increasing to 3-6 mg daily. Key considerations for dosage adjustments include:
- The patient's response to the medication
- Tolerability of side effects
- The presence of comorbid conditions or concomitant medications that may interact with cariprazine
- Regular monitoring of the patient's condition and adjustment of the dose as needed Common side effects that might prompt dose adjustments include:
- Restlessness
- Weight changes
- Drowsiness
- Akathisia
- Extrapyramidal symptoms It is essential to maintain regular appointments with the healthcare provider, report any concerning symptoms, and continue taking the medication as prescribed until directed otherwise. The most recent study 2 provides evidence for the efficacy and safety of cariprazine in the treatment of schizophrenia and bipolar disorder, with a significant decrease in PANSS scores and YMRS scores, and a low risk of metabolic complications. Additionally, a study 3 found that cariprazine had a favorable risk-benefit profile for the treatment of bipolar depression, with a number needed to treat (NNT) of 10 for response and 11 for remission, and a number needed to harm (NNH) of 51 for discontinuation due to an adverse event. Overall, the evidence suggests that cariprazine is a effective and safe treatment option for schizophrenia and bipolar disorder, with a favorable risk-benefit profile.
