Background and Purpose - 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.
