Quetiapine starting dose is which of the following?

• A. 25 mg/day
• B. 50 mg/day
• C. 75 mg/day
• D. 100 mg/day

Answer: (B)

Quetiapine is started at a low dose to balance achieving a therapeutic effect with minimizing sedative and blood pressure–lowering side effects. For the extended-release form commonly used in bipolar disorder and schizophrenia, the typical starting dose is 50 mg taken once daily. This amount provides some initial symptom control while allowing gradual uptitration by small steps (often 50 mg per day) to reach the desired therapeutic range, with tolerability monitored along the way. Lower starting doses like 25 mg are more characteristic of the immediate-release form and its tendency toward more pronounced early sedation, while higher starting doses (75–100 mg) raise the risk of dizziness, orthostatic hypotension, and excessive sedation without added early benefit. So 50 mg per day is the best starting dose in this context.
