FDA warns consumers not to use counterfeit Ozempic (semaglutide) found in U.S. drug supply chain


[12/21/2023] FDA continues to investigate counterfeit Ozempic (semaglutide) injection 1 milligram (mg) in the legitimate U.S. drug supply chain and has seized thousands of units of the product. The agency advises wholesalers, retail pharmacies, health care practitioners and patients to check the product they have received and not distribute, use, or sell products labeled with lot number NAR0074 and serial number 430834149057 as pictured below. Some counterfeit products may still be available for purchase.

FDA and Novo Nordisk (manufacturer of Ozempic) are testing the seized products and do not yet have information about the drugs’ identity, quality, or safety.

Additionally, analysis found the needles from the samples are counterfeit. Accordingly, the sterility of the needles cannot be confirmed, which presents an increased risk of infection for patients who use the counterfeit products. Based on analyses completed to date, other confirmed counterfeit components within the seized products are the pen label, accompanying health care professional and patient information, and carton. 

FDA is aware of five adverse events from this lot, none of which are serious and are consistent with known common adverse reactions to authentic Ozempic, which are nausea, vomiting, diarrhea, abdominal pain and constipation.

FDA recommends retail pharmacies only purchase authentic Ozempic through authorized distributors of Novo Nordisk and review the photographs and information to confirm the legitimacy of their shipments. Patients should only obtain Ozempic with a valid prescription through state-licensed pharmacies and check the product before using for any signs of counterfeiting.

FDA takes reports of possible counterfeit products seriously and works closely with other federal agencies and the private sector to help protect the nation’s drug supply. FDA’s investigation is ongoing, and the agency is working with Novo Nordisk to identify, investigate, and remove further suspected counterfeit semaglutide injectable products found in the U.S.

Health care professionals and consumers should report adverse events or side effects related to the use of this product to FDA’s MedWatch Safety Information and Adverse Event Reporting Program:

Entities, including online sellers, selling counterfeit and/or tampered medicines should be reported to FDA. Suspected counterfeit products may be reported to FDA by calling your local FDA consumer complaint coordinator or by reporting it directly at report suspected criminal activity

Retailers and patients may also contact Novo Nordisk customer care at 1-800-727-6500 Monday through Friday from 8:30 a.m. to 6 p.m. ET with questions or concerns.
