PLAINSBORO, N.J., April 14, 2025 /PRNewswire/ -- Novo Nordisk has become aware of several hundred units of Ozempic^® (semaglutide) injection 1 mg distributed outside the Novo Nordisk authorized supply chain in the US.

The seized counterfeit products feature lot number PAR0362 and illegitimate serial numbers beginning with the first eight digits 51746517 (illustrated above). Lot number PAR0362 is an authentic lot number. Only when both the lot number is coupled with the eight digits 51746517, is it counterfeit and should not be used.

As the investigation continues, further analyses, including extensive visual examination and chemical testing of the seized, counterfeit product is underway. Accordingly, neither Novo Nordisk nor FDA can confirm the contents or quality of the counterfeit product, which may present a safety risk for patients who use the counterfeit product.
