What people report to the FDA about technetium tc-99m sulfur colloid kit
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 40 reports naming technetium tc-99m sulfur colloid kit, and the FDA flagged 23% 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:
- radioisotope scan abnormal10 reports
- urticaria8 reports
- erythema5 reports
- procedural complication4 reports
- pruritus3 reports
- rash3 reports
- anaphylactic reaction2 reports
- asthenia2 reports
Read these as a signal, not a rate. A report does not mean technetium tc-99m sulfur colloid kit 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 section above.
