Several national guidelines recommend continuous use of antipsychotic medication after a psychotic episode in order to minimize the risk of relapse. However some studies have identified a subgroup of patients who can obtain remission of psychotic symptoms while not being on antipsychotic medication for a long period of time. This study investigated the long-term outcome and characteristics of patients in remission of psychotic symptoms with no use of antipsychotic medication at the 10-year follow-up.

The study was a cohort study including 496 patients diagnosed with schizophrenia spectrum disorders (ICD 10: F20 and F22-29). Patients were included in the Danish OPUS Trial and followed up 10 years after inclusion, where patient data was collected on socio-demographic factors, psychopathology, level of functioning and medication.

Among the patients, 30% had remission of psychotic symptoms at the time of the 10-year follow up with no current use of antipsychotic medication. This favorable outcome was associated with female gender, high GAF-F score, participation in the labor market and absence of substance abuse.

Results from several RCTs advise against discontinuation of antipsychotic medication, but our results from the 10-year follow-up indicate that a subgroup do obtain long-term remission while not being on antipsychotic medication. Hence, guidelines on antipsychotic medication do not pay sufficient attention to patients who discontinue antipsychotic medication and are still able to obtain remission of psychotic symptoms.
