title: Selective serotonin reuptake inhibitors and risk of hemorrhagic stroke.
abstract: OBJECTIVE
  Selective serotonin reuptake inhibitors (SSRI) are widely prescribed. Several reports have observed an increased bleeding risk associated with SSRI use, which is hypothesized to be secondary to their antiplatelet effect.
  
  
  METHODS
  We tested the hypothesis that SSRIs increase the risk for or potentiate the risk of hemorrhagic stroke associated with antiplatelets and anticoagulants.
  
  
  RESULTS
  In multivariate analysis, we found no increased risk associated with SSRI use for intracerebral hemorrhage (odds ratio=1.1, 95% CI: 0.7 to 1.8; P=0.63) or subarachnoid hemorrhage (odds ratio=0.6, 95% CI: 0.4 to 1.0; P=0.054). In addition, potentiation of risk with warfarin or antiplatelets was not observed.
  
  
  CONCLUSIONS
  Further studies with larger populations would be needed to exclude a small increase in intracranial hemorrhage risk with SSRI use.
