Initial oral dose range for Valbenazine is 1-2 mg once daily to three times daily, up to what maximum bid dose?

Initial oral dose range for Valbenazine is 1-2 mg once daily to three times daily, up to what maximum bid dose?

• A. 1-2 mg OD-TID up to 4 mg BID
• B. 10-20 mg QD
• C. 0.5 mg BID
• D. 50 mg QD

Answer: (A)

Understanding dose titration and how per-dose limits translate to twice-daily dosing. Valbenazine is started at a low dose and can be titrated upward from once daily to three times daily as tolerated. When you switch to twice-daily dosing, the per-dose ceiling is 4 mg. So the maximum you can take per administration is 4 mg, giving up to 8 mg in a day if taken twice daily. This aligns with starting at 1–2 mg once daily (up to three times daily) and then using a 4 mg per-dose maximum for BID dosing. The other options don’t fit this pattern: they propose doses that are either too high for a per-dose ceiling or don’t reflect the BID titration concept.
