FDA Alert: More Counterfeit Ozempic found in U.S. Supply Chain
Summary:
Issued: December 5, 2025
Medicine Name: Ozempic (semaglutide)
Reason for Warning: FDA recently seized dozens of units of counterfeit Ozempic in the legitimate supply chain.
FDA Alert
The FDA has seized multiple batches of counterfeit Ozempic 1 mg injections that entered the U.S. drug supply chain. The most recent counterfeit products are labeled with the lot number PAR1229, a number that also corresponds to the authentic product. These counterfeit pens can be identified by the placement of the EXP/LOT text on the left side of the expiration date and lot number (authentic pens place this text above the date and lot number).
Counterfeit Ozempic raises serious safety concerns because the FDA does not yet know the identity, quality, sterility, or safety of the seized products. Previous investigations (2023–2025) found additional counterfeit lots, including PAR0362 and NAR0074, with issues such as fake components and non-sterile needles that increase infection risk. Adverse events, none of which have been linked to the counterfeit units so far, should be reported through FDA MedWatch.
