Most-Reported Reactions

Counts of the reactions most often cited in FAERS submissions that named Enbrel. Inclusion here does not establish causation - submitters describe what was observed, not what was confirmed. One submission can list several reactions, so the totals exceed the report count.

Severity Outcomes

Severity flags recorded across the 592,885 FAERS submissions that named Enbrel. Each bar shows the count of those reports carrying that flag. A single case can carry more than one (a hospitalization that became life-threatening, for example), so these bars are independent rates - they don't sum to 100%. Inclusion of a case under any flag does not establish that the drug caused the outcome.
