2.3 Recommended Dosage in Manic or Mixed Episodes Associated with Bipolar I Disorder The starting dosage of VRAYLAR is 1.5 mg orally once daily. Increase the dosage to 3 mg orally once daily on Day 2. The recommended dosage range is 3 mg to 6 mg orally once daily. Depending upon clinical response and tolerability, further dose adjustments can be made in 1.5 mg or 3 mg increments. The maximum recommended dosage is 6 mg orally once daily.

From the Research
Yes, you can increase the dose of Vraylar (cariprazine) 1.5mg in a patient with bipolar 1 disorder after 4 weeks if needed, as the recommended dose range for Vraylar in bipolar disorder is 1.5-6mg once daily, with 3mg being a common target dose 2. When increasing the dose, it's best to do so gradually, such as moving from 1.5mg to 3mg daily. Before increasing, evaluate the patient's current symptom control and any side effects they may be experiencing.
Key Considerations
- Common side effects include akathisia, extrapyramidal symptoms, and weight gain, which should be monitored 3.
- The full therapeutic effect of Vraylar may take several weeks to manifest due to its long half-life and the time needed to reach steady-state concentrations, so a 4-week assessment period is appropriate.
- If increasing the dose, continue to monitor the patient closely for both improved efficacy and potential side effects.
- Cariprazine works as a partial agonist at dopamine D2/D3 receptors with preferential binding to D3 receptors, which may contribute to its effectiveness in treating both manic and depressive symptoms in bipolar disorder.
Monitoring and Adjustments
- Regularly assess the patient's response to treatment and adjust the dose as needed to achieve optimal efficacy while minimizing side effects.
- Consider the results of the study by 2, which found that early improvement with cariprazine may predict eventual treatment response in bipolar I disorder.
- Be aware of the potential for weight gain, particularly at higher doses, as noted in the study by 4.
