  • Counterfeit reported

Counterfeit weight loss injection medicines, such as Ozempic, have already been found in Australia, Belgium, IrelandAzerbaijan, Egypt, Iraq, Jordan, Lebanon, Nigeria, Turkey, Uzbekistan, Russia, Germany, Austria, the U.K and the United States.

On June 15, 2023 Ozempic maker Novo Nordisk warned that a fake version of the diabetes drug had been found in the U.S. The counterfeit injection pen, which contained insulin instead of semaglutide, was reportedly purchased at a retail pharmacy.

In December 2023, U.S. Food and Drug Administration announced that it had seized "thousands of units" of counterfeit Ozempic, and shared images of the relevant products.

These confirmed fakes are happening alongside an uptick in black market, unauthorized sales of Ozempic and its sister drugs, Wegovy and Rybelsus, on social media platforms and online marketplaces, according to a recent report from the National Association of Boards of Pharmacy, "RogueRX Activity Report: Injectable Weight Loss Drugs: How Illegal Online Drug Sellers Are Taking Advantage of Patients".

Did you know there are less than 100 safe online pharmacies for Americans to buy from? There are tens of thousands of unlicensed dangerous ones operating online. Learn how to spot them.

Are you worried about whether your Ozempic is genuine? These are Novo Nordisk's tips for how to tell.
