What people report to the FDA about ASPARAGINASE
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 9,790 reports naming ASPARAGINASE — the active ingredient in Elspar, and the FDA flagged 97% 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:
- febrile neutropenia1,108 reports
- neutropenia569 reports
- pyrexia555 reports
- sepsis445 reports
- vomiting352 reports
- pneumonia340 reports
- bacterial infection332 reports
- thrombocytopenia323 reports
Read these as a signal, not a rate. A report does not mean ASPARAGINASE 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.
