PLAINSBORO, N.J., December 21, 2023 – At Novo Nordisk, patient safety is a top priority, and we are committed to supporting the active fight against counterfeit Novo Nordisk products and other illegal activity in the market.

Novo Nordisk has become aware of several thousand units of Ozempic® (semaglutide) injection 1 mg determined to be outside the Novo Nordisk authorized supply chain. Product that contains lot number NAR0074 and serial number, 430834149057, as pictured below, are counterfeit and should not be used.

FDA has issued an alert on this counterfeit product, and Novo Nordisk is working with FDA to identify and investigate any further potential counterfeit semaglutide injectable products found in the U.S.

To date there have been five adverse events reported from this lot, all of which have been categorized as non-serious, and are consistent with the adverse event profile of authentic Ozempic® product. It is not clear, at this time, if these incidents included legitimate product or the counterfeit product.

FDA and Novo Nordisk are testing the seized product and do not yet have conclusive information about the drugs’ identity, quality, or safety.

Analyses and testing of the product is underway. Visual examination confirms that needles from these samples are counterfeit. Accordingly, Novo Nordisk cannot confirm their sterility, which may present an increased risk of infection for patients who use the counterfeit product. However, additional testing is needed to definitively determine product composition.

Additional counterfeit components are the labeling on the pen, the accompanying literature, and the carton.

Semaglutide.com is available as a resource hub for US consumers, healthcare providers, and retailers to provide information about responsible use of semaglutide, including how to spot a counterfeit product.
