Important caveats

FAERS report counts are a reporting signal, not a clinical assertion of causation. Higher report volumes correlate with: larger treated populations, established manufacturer pharmacovigilance infrastructure, sicker patient populations (specialty biologics for serious disease will always attract more reports than common over-the-counter agents), and reporter familiarity with the reporting workflow.

The paid FAERS Signal Surveillance product adds the disproportionality analysis (Information Component, Empirical Bayes Geometric Mean, Proportional Reporting Ratio) that normalizes these confounders and surfaces emerging signal against the FAERS baseline. See the product page.
