Analysis of the Safety Profile of Commonly Used Procoagulants Using the FDA Adverse Event Reporting System

Conclusions:Our analysis found that the rate of reports of death and MI were higher with rFVIIa than other procoagulants, while reports of ischemic stroke and intracranial hemorrhage were more common with PCCs. rFVIIa has been associated with cardiovascular before, a finding reiterated by our study. There are notable limitations of this type of analysis, including the reliance on the accurate reporting of adverse events to the FDA, possibility of duplications of reports in the FAERS database, and the importance of not conflating correlation with causation as it relates to these events. The association between rFVIIa and increased death may be due to rFVIIa's history of off-label use in trauma patients and other patient groups at higher risk for mortality. While 4PCC may be the procoagulant of the present, it does not have a perfect safety profile, and further study is needed to better characterize the complications of 4PCC and ensure that it is used in such a way as to not under- or over-treat the condition.DisclosuresNo relevant conflicts of interest to declare.
