AbstractBackground There is concern that selective serotonin reuptake inhibitors ( SSRI s) substantially increase bleeding risk in patients taking anticoagulants. Methods and Results We studied 737 patients taking SSRI s in the ROCKET AF (Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared With Vitamin K Antagonism for Prevention of Embolism and Stroke Trial in Atrial Fibrillation) trial of rivaroxaban compared with warfarin for the prevention of stroke/systemic embolism in patients with atrial fibrillation. These patients were propensity score matched 1:1 to 737 patients not taking SSRI s. The primary outcome measure was major and nonmajor clinically relevant bleeding events, the principal safety outcome in ROCKET AF . Over a mean 1.6 years of follow-up, the rate of major/ nonmajor clinically relevant bleeding was 18.57 events/100 patient-years for SSRI users versus 16.84 events/100 patient-years for matched comparators, adjusted hazard ratio ( aHR ) of 1.16 (95% confidence interval [CI], 0.95-1.43). The aHR s were similar in patients taking rivaroxaban ( aHR 1.11 [95% CI, 0.82-1.51]) and those taking warfarin ( aHR 1.21 [95% CI, 0.91-1.60]). For the rarer outcome of major bleeding, the aHR for SSRI users versus those not taking SSRI s was 1.13 (95% CI, 0.62-2.06) for rivaroxaban; for warfarin, the aHR was higher, at 1.58 (95% CI , 0.96-2.60) but not statistically significantly elevated. Conclusions We found no significant increase in bleeding risk when SSRI s were combined with anticoagulant therapy, although there was a suggestion of increased bleeding risk with SSRI s added to warfarin. While physicians should be vigilant regarding bleeding risk, our results provide reassurance that SSRI s can be safely added to anticoagulants in patients with atrial fibrillation .
