Fanapt must be titrated slowly from a low starting dose to avoid orthostatic hypotension due to its alpha-adrenergic blocking properties. Recommended starting dose: 1 mg twice daily. Increases to reach the target dose range of 6 to 12 mg twice daily may be made with daily dosage adjustments to 2 mg twice daily, 4 mg twice daily, 6 mg twice daily, 8 mg twice daily, 10 mg twice daily, and 12 mg twice daily on days 2, 3, 4, 5, 6, and 7, respectively. Efficacy has been demonstrated in a dose range of 6 to 12 mg twice daily. The maximum recommended dose is 12 mg twice daily (24 mg/day). Doses above 24 mg/day have not been systematically evaluated in the clinical trials.
