title: Citalopram-induced bleeding due to severe thrombocytopenia.
abstract: BACKGROUND
  In case reports and observational studies, serotonin reuptake-inhibitors (SSRIs) have been linked to an increased risk of bleeding, possibly due to platelet dysfunction as a consequence of serotonin-uptake blockade into platelets.
  
  
  OBJECTIVE
  The authors propose that bleeding as a result of SSRI use may also be caused by other mechanisms.
  
  
  METHODS
  Here, the authors report on a 32-year-old woman with hemorrhages resulting from severe drug-induced immune thrombocytopenia after 4 weeks of citalopram therapy.
  
  
  RESULTS
  After withdrawal of citalopram and treatment with platelet concentrates and prednisolone, the patient recovered completely.
  
  
  CONCLUSIONS
  As this case report shows, drug-induced immune thrombocytopenia may present another possible mechanism for bleeding in SSRI-treated patients.
