Abstract

Purpose: In response to a large trial, the World Health Organization broadened their recommendation on tranexamic acid to be used for post-partum hemorrhage. A 2013 French periodic safety update report warned of an abnormally high rate of renal cortical necrosis associated with tranexamic acid and other drugs for severe post-partum hemorrhage. We aimed to identify the reporting incidence of adverse thrombo-embolic events among women in child-bearing age who received tranexamic acid, with a focus on renal vascular and ischemic conditions. Methods: We analyzed individual case safety reports (ICSRs) on renal vascular and ischemic conditions, pulmonary thrombotic and embolic conditions, and peripheral embolism and thrombosis from the database of the World Health Organization – Uppsala Monitoring Centre (WHO-UMC). ICSRs were restricted to reports including tranexamic acid as a suspected drug, sex reported as female, and reported age between 18 and 44 years. Reporting odds ratios (RORs) and 95% confidence intervals (95% CIs) were calculated by comparing ICSRs on tranexamic acid to all other drugs in VigiBase. Results: Within 2245 included ICSRs on tranexamic acid, we identified 29 reports of adverse renal vascular and ischemic conditions, 42 reports of pulmonary thrombotic and embolic conditions, and 41 reports of peripheral embolism and thrombosis. RORs were statistically significant by 32.6-fold (32.62, 95% CI: 22.50–47.29), 2.5-fold (2.52, 95% CI: 1.85–3.42), and 2.7-fold (2.67, 95% CI: 1.96–3.64), respectively, when compared to any other drug within VigiBase. Conclusion: Tranexamic acid might bear an increased risk for renal ischemic adverse drug events in women of child-bearing age.
