What is the starting dose for Quetiapine?

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

Answer: (A)

Quetiapine is started at a very low dose to balance getting some antipsychotic benefit with minimizing early side effects like sedation and dizziness. The usual starting regimen for schizophrenia is 25 mg twice daily, which totals 50 mg per day. This small amount lets you begin addressing symptoms while keeping tolerability high, and it can be gradually increased over the first week or two toward a therapeutic range as needed. From there, doses are typically stepped up to reach an effective daily total (often in the range of several hundred milligrams, tailored to the patient’s response and tolerability). Starting at 50 mg/day also aligns with the goal of reducing adverse effects early in treatment, compared with jumping to higher initial doses. The other options are less appropriate as starting doses because 25 mg/day alone is usually not enough to produce antipsychotic effect, while 75 mg/day or 100 mg/day begin at a level that can increase side effects before efficacy is fully established.
