Quetiapine is an atypical antipsychotic with a good safety profile permitting its administration beyond the maximum dose of 800 mg/day. We report the case of a patient with a resistant schizophrenia treated with high doses of quetiapine (up to 2000 mg/day) combined with drug monitoring and with favourable therapeutic response and tolerance.
