| DOSAGE AND ADMINISTRATION
Maintenance Treatment: Efficacy was demonstrated with SAPHRIS in a maintenance trial in patients with schizophrenia. The starting dose in this study was 5 mg twice daily with an increase up to 10 mg twice daily after 1 week based on tolerability. While there is no body of evidence available to answer the question of how long the schizophrenic patient should remain on SAPHRIS, patients should be periodically reassessed to determine the need for maintenance treatment.
Monotherapy: The recommended starting dose of SAPHRIS, and the dose maintained by 90% of the patients studied, is 10 mg twice daily. The dose can be decreased to 5 mg twice daily if warranted by adverse effects or based on individual tolerability.
In controlled monotherapy trials, the starting dose for SAPHRIS was 10 mg twice daily. On the second and subsequent days of the trials, the dose could be lowered to 5 mg twice daily, based on tolerability, but less than 10% of patients had their dose reduced. The safety of doses above 10 mg twice daily has not been evaluated in clinical trials.
Adjunctive Therapy: The recommended starting dose of SAPHRIS is 5 mg twice daily when administered as adjunctive therapy with either lithium or valproate. Depending on the clinical response and tolerability in the individual patient, the dose can be increased to 10 mg twice daily. The safety of doses above 10 mg twice daily as adjunctive therapy with lithium or valproate has not been evaluated in clinical trials.
Maintenance Treatment: While there is no body of evidence available to answer the question of how long the bipolar patient should remain on SAPHRIS, whether used as monotherapy or as adjunctive therapy with lithium or valproate, it is generally recommended that responding patients be continued beyond the acute response. If SAPHRIS is used for extended periods in bipolar disorder, the physician should periodically re-evaluate the long-term risks and benefits of the drug for the individual patient.
