For adults, the manufacturer recommends a Banzel starting dose of 200 mg twice a day, but you and your doctor may choose to start more slowly or more rapidly to fit your particular needs. Dosing can be increased by adding an extra 200 (or 400) mg twice a day every two days, to a maximum of 1600 mg twice a day (3200 mg per day total).

Children will usually be started at doses of approximately 10 mg/kg/day administered in two equally divided doses. Dosing can increase by adding additional 10 mg/kg amounts every two days, until the child is taking 45 mg/kg/day or a maximum of 3200 mg/day, divided into two doses each day.
