FDA warns about fake Ozempic in U.S. supply chain. “Novo Nordisk, the maker of Ozempic and the weight loss drug Wegovy, told the FDA on April 3 that counterfeit 1-milligram injections were being distributed outside its authorized supply chain in the U.S., the agency said in a news release. That means it likely entered the market through unofficial means, like unauthorized distributors or resellers.”
