| Summary: | Background: Selective serotonin reuptake inhibitors (SSRIs) are among the most commonly prescribed antidepressants and are generally considered safe. However, emerging data suggest a potential association with intracranial hemorrhage (ICH), especially among elderly patients and those on anticoagulation. Methods: We conducted a retrospective pharmacovigilance analysis using data from the U.S. Food and Drug Administration’s Adverse Event Reporting System (FAERS). Reports up to May 2025 listing an SSRI (sertraline, fluoxetine, paroxetine, escitalopram, citalopram, or fluvoxamine) as a suspect or interacting drug and involving an ICH event were included. Disproportionality was assessed using reporting odds ratios (RORs) with 95% confidence intervals. Results: Among 226 eligible ICH cases, sertraline (30.5%), paroxetine (28.8%), and fluoxetine (27.9%) were most frequently implicated. Sertraline showed a strong signal for cerebral hemorrhage (ROR = 4.97), while fluoxetine was associated with subarachnoid hemorrhage (ROR = 4.51). Sertraline had a pronounced signal among patients aged >60 years (ROR = 7.92) and in combination with anticoagulants (ROR = 9.56). Fluoxetine was underrepresented in elderly cases. Given the very small number of fluvoxamine-related cases (n = 2), interpretation should be cautious due to limited statistical power. Gender-stratified analyses showed female predominance in sertraline-related ICH and male predominance for paroxetine. Citalopram demonstrated a potentially protective profile with inverse association with cerebral hemorrhage. Conclusions: This study highlights significant differences in ICH reporting patterns across SSRIs, modified by patient age, gender, and co-medication. These findings underscore the need for individualized SSRI prescribing, particularly in patients receiving anticoagulant therapy particularly in elderly patients and those receiving anticoagulant therapy, where sertraline and fluoxetine may pose increased risk. |
