What people report to the FDA about DARATUMUMAB

The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 17,983 reports naming DARATUMUMAB — the active ingredient in Darzalex, and the FDA flagged 94% 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:

plasma cell myeloma1,739 reports
neutropenia1,203 reports
pneumonia1,185 reports
thrombocytopenia800 reports
diarrhoea705 reports
pyrexia690 reports
fatigue671 reports
anaemia657 reports

Read these as a signal, not a rate. A report does not mean DARATUMUMAB 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.
