What people report to the FDA about INTERFERON ALFA-2B
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 1,349 reports naming INTERFERON ALFA-2B — the active ingredient in Intron A, and the FDA flagged 92% 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:
- fatigue95 reports
- anaemia93 reports
- pyrexia87 reports
- nausea85 reports
- malaise69 reports
- thrombocytopenia64 reports
- diarrhoea63 reports
- decreased appetite60 reports
Read these as a signal, not a rate. A report does not mean INTERFERON ALFA-2B 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.
