title: Deliberate self-harm and antidepressant drugs. Investigation of a possible link.
abstract: BACKGROUND
  It is not clear if the frequency of deliberate self-harm (DSH) is the same in patients taking different pharmacological classes of antidepressant drugs.
  
  
  OBJECTIVE
  To compare the frequency of DSH in patients who had been prescribed a tricyclic antidepressant (TCA) or a selective serotonin reuptake inhibitor (SSRI) prior to the DSH event.
  
  
  METHODS
  This was a prospective study in 2776 consecutive DSH cases attending an accident and emergency department. The incidence of DSH in TCA-treated cases and SSRI-treated cases is expressed as number of DSH events per 10 000 prescriptions of each antidepressant.
  
  
  RESULTS
  Significantly more DSH events occurred following the prescription of an SSRI than that of a TCA (P<0.001). The occurrence of DSH was highest with fluoxetine and lowest with amitriptyline.
  
  
  CONCLUSIONS
  Merely prescribing safer-in-overdose antidepressants is unlikely to reduce the overall morbidity from DSH.
