Trends in copper versus hormonal intrauterine device breakage reporting within the United States' Food and Drug Administration Adverse Event Reporting System

Contraception, 118, 109909, 2023

Abstract

Objective

To examine trends in national reporting of broken intrauterine devices (IUDs).

Study design

We enumerated IUD device "breakage" reports in the Food and Drug Administration Adverse Event Reporting System from inception (1998) until February 2022. We explored associations of breakage with IUD type (copper versus hormonal), year reported, reporter (consumer versus clinician), and patient characteristics (age and weight).

Results

We identified 4144 breakage reports for copper versus 2140 for hormonal IUDs. Among the 170,215 adverse events reported, breaks were disproportionately reported for copper (9.6%) versus hormonal (1.7%) IUDs.

Conclusion

National pharmacovigilance data suggests disproportionate breakage in copper versus hormonal IUDs though the true prevalence of breaks cannot be calculated from this dataset.
