Elderly

As with other antipsychotics and antidepressants, quetiapine 50 mg should be used with caution in the elderly, especially during the initial dosing period. The rate of dose titration of quetiapine 50 mg may need to be slower, and the daily therapeutic dose lower, than that used in younger patients. The mean plasma clearance of quetiapine was reduced by 30% to 50% in elderly patients when compared to younger patients. Elderly patients should be started on 50 mg/day. The dose can be increased in increments of 50 mg/day to an effective dose, depending on the clinical response and tolerability of the individual patient.
