Which dosing description matches a low-dose quetiapine regimen mentioned?

• A. 5-10 mg daily; increase by 1 mg/day to max 8 mg
• B. 1-2 mg daily; increase by 0.5 mg/day to max 4 mg
• C. 2-3 mg daily; increase by 1 mg/day to max 6 mg/day
• D. 10 mg daily; increase by 2 mg/day to max 20 mg

Answer: (C)

Low-dose regimens aim for very small starting doses with slow, cautious titration to minimize side effects while watching for how the patient responds. Starting at 2–3 mg daily and increasing by 1 mg each day to a maximum of 6 mg daily embodies that approach: the dose stays in a tiny range, allowing gradual assessment of tolerability and effect, and keeps the risk of sedation, blood pressure drop, or QT prolongation low. The other plans either start at higher doses, jump by larger amounts, or cap at a level that isn’t consistent with a truly low-dose, slow-tade approach, so they don’t reflect the same careful escalation intended by a low-dose regimen.
