What people report to the FDA about LARONIDASE
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 865 reports naming LARONIDASE — the active ingredient in Aldurazyme, and the FDA flagged 64% 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:
- pyrexia129 reports
- inappropriate schedule of product administration61 reports
- cough54 reports
- pneumonia54 reports
- fatigue51 reports
- malaise46 reports
- covid-1944 reports
- dyspnoea42 reports
Read these as a signal, not a rate. A report does not mean LARONIDASE 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.
