What people report to the FDA about SAMARIUM SM-153 LEXIDRONAM PENTASODIUM
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 1 reports naming SAMARIUM SM-153 LEXIDRONAM PENTASODIUM — the active ingredient in Quadramet, and the FDA flagged 100% 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:
- blood pressure increased1 reports
- haemolysis1 reports
- intestinal obstruction1 reports
- leukocytosis1 reports
- malignant neoplasm progression1 reports
- respiratory alkalosis1 reports
- small intestinal obstruction1 reports
Read these as a signal, not a rate. A report does not mean SAMARIUM SM-153 LEXIDRONAM PENTASODIUM 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.
