[Insulin intoxications caused by falsified semaglutide].
Editor's note
This two-case report speaks directly to peptide-market safety: two people without diabetes or obesity injected semaglutide obtained without a prescription and presented in a coma with severe hypoglycemia, low potassium and hypothermia — caused, on investigation, not by semaglutide but by synthetic insulin contaminating or substituting the product. The authors underscore the clinical logic: semaglutide monotherapy is not associated with significant hypoglycemia in healthy people, so the profound low blood sugar (requiring up to two days of continuous glucose infusion) pointed to a falsified product. This is a vivid illustration of the risk of buying peptides outside regulated supply chains, where quality controls are absent. As a case report it establishes occurrence, not frequency. The actionable point is provenance: falsified 'semaglutide' can contain dangerous undeclared drugs, and regulators should be notified promptly.
Plain-language abstract
This report describes two people who became severely ill after injecting semaglutide they had bought without a prescription, outside the regular healthcare system. Neither had diabetes or obesity. Both arrived at the hospital in a coma with dangerously low blood sugar, low potassium and low body temperature. Testing showed the cause was not semaglutide itself but synthetic insulin — meaning the product was fake or contaminated. The doctors point out that semaglutide on its own does not usually cause serious low blood sugar in healthy people, which was the clue that something else was in the injection. The patients needed up to two days of continuous sugar infusion to recover. The key message is that illegally obtained, unregulated 'semaglutide' can contain hidden, life-threatening substances because it lacks proper quality control, and that health authorities should be told so they can stop these falsified products from spreading. This is a report of two cases, so it shows the danger exists rather than how common it is.
