Which antipsychotic has a starting dose of 50 mg/day?

• A. Asenapine
• B. Quetiapine
• C. Clozapine
• D. Lurasidone

Answer: (B)

Starting doses of antipsychotics are chosen to balance how well the drug works with how well a patient tolerates it. Different medicines and formulations have different initial amounts and titration schedules. Quetiapine has two formulations to consider. The extended‑release form is commonly started at 50 mg once daily, with gradual increases up to a typical range of 300–800 mg per day as needed. This makes 50 mg/day a standard starting point for the ER version in schizophrenia. The immediate‑release form, by contrast, usually starts lower (for example, around 25 mg twice daily) and is titrated more slowly. Other antipsychotics generally do not start at 50 mg per day: asenapine typically begins at 10 mg twice daily; clozapine starts much lower (around 12.5 mg daily, then titrated) due to safety considerations; lurasidone commonly starts around 40 mg daily with food. So, the starting dose of 50 mg/day is characteristic of quetiapine when using the extended‑release formulation.
