Swissmedic issues warning against falsified and misleading “GLP-1” weight loss products
Bern, 26.08.2025 — Swissmedic issues warning about the increasing number of falsified, misleading or unauthorised weight loss products currently on offer that make reference to GLP-1 active substances. Such preparations may contain untested, undeclared or harmful substances, and may also be of insufficient quality or contain the incorrect dosage. The use of these products carries significant health risks. Furthermore, “slimming preparations” are now also being sold as nutritional supplements in addition to illegal weight-loss injections. These use misleading names, make fraudulent use of the Swissmedic logo or carry invented quality marks with the aim of deliberately deceiving consumers.
