What people report to the FDA about PARATHYROID HORMONE
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 4,546 reports naming PARATHYROID HORMONE — the active ingredient in Natpara, and the FDA flagged 59% 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:
- recalled product901 reports
- hypocalcaemia790 reports
- blood calcium decreased707 reports
- paraesthesia368 reports
- muscle spasms362 reports
- headache258 reports
- blood calcium increased213 reports
- nausea206 reports
Read these as a signal, not a rate. A report does not mean PARATHYROID HORMONE 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.
