Purpose To describe the characteristics of adverse event reporting in the United States (US) Food and Drug Administration Adverse Event Reporting System (FAERS) before and after the outbreak of the COVID‐19 pandemic. Methods We included all FAERS reports from the US and Canada from November 7, 2019 to July 15, 2020 and divided the study period into three equal time intervals (pre‐pandemic, first pandemic, second pandemic). We focused on methotrexate, a broadly used drug unrelated to COVID‐19, and (hydroxy)chloroquine, another broadly used drug implicated in COVID‐19 treatment. Using descriptive statistics, we compared reporting characteristics before and after the COVID‐19 outbreak. Results During the study period, 366 998 cases (60% female, median age: 59 years) were submitted to FAERS. The daily median number of reports (1796 in the pre‐pandemic, 1810 in the second pandemic time interval) and other characteristics remained stable. The daily median number of reports for methotrexate decreased from 28 in the pre‐pandemic to 15 in the second pandemic time interval, with no considerable differences in other characteristics. The daily median number of reports for (hydroxy)chloroquine increased slightly from 1 in the pre‐pandemic to 3 in the second pandemic time interval, while there were also changes in the demographics of cases and an increase in the proportion of cases reported by health professionals. Conclusions The overall reporting to FAERS did not change after the outbreak of the COVID‐19 pandemic. However, some stimulated reporting was observed for (hydroxy)chloroquine, highlighting the need for caution when conducting pharmacovigilance analyses with substances related to COVID‐19.
