Antidepressants and violence: Problems at the interface of medicine and law

Abstract

Recent regulatory warnings about adverse behavioural effects of antidepressants in susceptible individuals have raised the profile of these issues with clinicians, patients, and the public. We review available clinical trial data on paroxetine and sertraline and pharmacovigilance studies of paroxetine and fluoxetine, and outline a series of medico-legal cases involving antidepressants and violence. Both clinical trial and pharmacovigilance data point to possible links between these drugs and violent behaviours. The legal cases outlined returned a variety of verdicts that may in part have stemmed from different judicial processes. Many jurisdictions appear not to have considered the possibility that a prescription drug may induce violence. The association of antidepressant treatment with aggression and violence reported here calls for more clinical trial and epidemiological data to be made available and for good clinical descriptions of the adverse outcomes of treatment. Legal systems are likely to continue to be faced with cases of violence associated with the use of psychotropic drugs, and it may fall to the courts to demand access to currently unavailable data. The problem is international and calls for an international response. © 2006 Healy et al.
