Antipsychotic medications are registered for the use in psychosis, mania and agitation. the aim of our study was to assess the off-label use of atypical antipsychotics (AA) at the Crisis Intervention Unit (CIU).

Hospital records of 280 patients that were treated at the CIU in year 2007 were included to the observational study. Patients were screened for diagnosis (ICD-10), gender, age, suicidal behaviour and for prescribed psychotropic medications. Off-label use of atypical antipsychotics for diagnoses other than psychosis was evaluated.

Most hospitalised patients suffered for stress related disorders: adjustment disorder F43.2 (34%), acute stress disorder F 43.0 (2%), mixed anxiety-depression disorder F41.2 (19%), depression (24%), anxiety disorders (4%) and other disorders (17%). Patients were treated with antidepressants (92%), benzodiazepines (55%), hypnotics (44%) and mood stabilising drugs (9%) during their stay at the CIU. at discharge from hospital benzodiazepines (31%) and hypnotics (12%) were prescribed in lower percentages. 51% of patients received AA at least once during their stay at the CIU, 49% received AA for off-label use and it was prescribed for most of the hospital stay (for 87% of the time). Average daily CPU at admission to the hospital was 107.52 and at the discharge it was 100.33. No significant differences were noted among the different diagnoses for off-label AA use.

Atypical antipsychotics are widely used for indications other than psychosis, even though the long-term effects of their use are not yet known and safety issues remain to be examined further.
