The development of severe tardive dystonia after short-term use of low-dose Fluspirilen is described. A 39-year-old woman was treated with Fluspirilen IM by her family doctor for reactive depression. She did received no other neuroleptic agents and no risk factors for the development of tardive dyskinesia (e.g. old age or organic brain damage) were present. For the first time a relation between short-term monotherapy with Fluspirilen and tardive dyskinesia appears highly probable. The use of Fluspirilen for the treatment of psychogenic disturbances should therefore be considered carefully.
