Drug-induced akathisia and suicidal tendencies in psychotic patients.

Five patients, while being treated with high potency antipsychotic drugs developed akathisia and tended towards committing suicide as a consequence of the inner agitation and restlessness they were suffering. Upon discontinuation of the respective medication or switching to low potency drugs, as well as addition of anti-parkinson drugs or benzodiazepines, the akathisia and suicidal tendencies abated. Clinicians ought to be aware of suicidal impulses emerging in patients suffering from akathisia. By prompt recognition and treatment of akathisia such suicidal tendencies and attempts can be prevented.
