Study Arms (2)

Therapeutic Drug Monitoring

EXPERIMENTAL

Physicians receive dosing advice based on measured blood levels of risperidone and 9-OH-risperidone.

Other: Therapeutic Drug MonitoringOther: Risperidone plasma level

Care As Usual

ACTIVE COMPARATOR

Physician decides on possible dosing changes without receiving advice based on blood levels.

Other: Risperidone plasma level

Interventions

Physician receives dosing advice based on risperidone plasma level.

Therapeutic Drug Monitoring

Plasma levels of risperidone and 9-OH risperidone are measured in a Dried Blood Spot.
