What people report to the FDA about omega-3-acid ethyl esters

The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 2,164 reports naming omega-3-acid ethyl esters, and the FDA flagged 71% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:

  • product odour abnormal175 reports
  • diarrhoea104 reports
  • nausea97 reports
  • chest pain92 reports
  • malaise78 reports
  • dyspnoea68 reports
  • fatigue68 reports
  • abdominal discomfort63 reports

Read these as a signal, not a rate. A report does not mean omega-3-acid ethyl esters caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label section above.
