| Level of Agitation | Haloperidol | Risperidone* | Olanzapine | Quetiapine |
| Mild | 0.5 - 2 mg/d | 0.5 - 1 mg/d | 2.5 - 5 mg/d | 25 - 50 mg bid |
| Moderate | 2 - 5 mg/d | 1 - 3 mg/d | 5 - 10 mg/d | 50 - 150 mg bid |
| Severe | 5 - 10 mg/d | 3 - 6 mg/d | 10 - 20 mg/d | 150 - 300 mg bid |
★Doses of risperidone should be titrated at the rate of 1-2 mg/d because of the risk of orthostatic hypotension.
In older or frail patients, antipsychotic dosages for mild levels of agitation are often sufficient and avoid adverse effects.
