Counterfeit and compounded injected diabetes and obesity treatments — twin threats to American patients

Patients in the United States and around the world who are seeking Ozempic, Mounjaro, Wegovy or Zepbound are encountering a dangerous array of counterfeits as well as compounded semaglutide or tirzepatide falsely marketed as the real thing.

According to a recent report from the National Association of Boards of Pharmacy, these sales are happening alongside an uptick in black market sales of Ozempic and related drugs made with semaglutide, liraglutide, and tirzepatide on social media platforms and online marketplaces.

These unregulated, injected products are a serious threat to patient health.

Fakes in the U.S. and worldwide

Counterfeit Ozempic has been reported in dozens of countries since 2023, including the United States. Many of these fakes are relabeled insulin pens, which can be very dangerous; they have caused hospitalizations for hypoglycemia in the U.S. and Austria.

In June 2023 Ozempic maker Novo Nordisk warned that a fake version of the diabetes drug had been found in the U.S. The counterfeit injection pen, which contained insulin instead of semaglutide, was reportedly purchased at a retail pharmacy.

Unfortunately, this wasn't just one pen. In December 2023, the U.S. Food and Drug Administration announced that it had seized "thousands of units" of counterfeit Ozempic, and shared images of the relevant products. At that time, FDA had not finished testing the contents of the pens, but had identified that the needles accompanying them were counterfeit.

Because the sterility of the needles cannot be confirmed, they present an increased risk of infection for patients using the fake products.

Compounded injectables

All kinds of clinics, medical spas and wellness-oriented businesses are selling Wegovy, Mounjaro and their sister drugs lately, and most of them are doing it online. Generally, though, these sites aren't selling genuine, FDA-approved Wegovy.

They're selling compounded versions of their active ingredients, semaglutide and tirzepatide.

Compounding pharmacies are permitted to make compounded substitutes for Ozempic, Wegovy, Mounjaro and Zepbound if they are in shortage. However, compounded drugs are not as safe as commercially-marketed ones because the FDA does not review them for effectiveness or quality. It's also more difficult to find the source of problems with compounded medicines, since they aren't tracked as part of the DSCSA.

There are reasons to be wary of these compounded injectables:

If you are taking compounded versions of these drugs, please heed the FDA's advice. Only use compounded drugs if FDA-approved medicines are unavailable; buy these medicines from licensed pharmacies or outsourcing facilities with a prescription from a licensed health care provider; and be alert to unexpected side effects that could be the result of unregulated ingredients.
