Olanzapine - How long does it take olanzapine to work?Thanks?

In 2004, nearly 25 percent of the elderly nursing home population received antipsychotics, with most receiving atypicals; males were more likely than females to receive them.

One year after the 2005 Food and Drug Administration (FDA) advisory warning, no state had actually changed its prior authorization policy in response to limit the use of atypicals in dementia. However, a more recent study concluded that the FDA advisory decreased the use of atypical antipsychotics in the U.S., especially among elderly dementia patients.

In 2003–2004, antipsychotics were prescribed in only 1 percent of overall mental health visits by children and adolescents, with most (99 percent) of these visits involving prescribing of atypicals.

Male children/adolescents were more likely than females to be prescribed atypical antipsychotics. Risperidone was the atypical most commonly prescribed to children.

At one large acute-care psychiatric hospital, quetiapine was used extensively for off-label conditions, and in a variety of off-label doses: only a quarter of patients had one of the diagnoses for which quetiapine is approved, and only a third received quetiapine in a standing dose regimen. Depression and substance-use disorders were found to be the most common associated diagnoses.

Atypicals are frequently prescribed to treat PTSD in the U.S. Department of Veterans Affairs (VA) health system."
