Is compounded semaglutide the same as Ozempic?
No. Compounded semaglutide is not FDA-approved, so the FDA has not reviewed its safety, effectiveness or quality, while Ozempic (semaglutide) is an FDA-approved medicine. The FDA has told sellers not to call compounded versions generic or the same as approved drugs, and it warns that some contain different salt forms.
What is the difference between compounded semaglutide and Ozempic?
The FDA says compounded drugs “are not FDA approved,” which means “the agency does not review compounded drugs for safety, effectiveness or quality before they are marketed.”1
They are not generics either. The FDA says compounded drugs are not the same as generic drugs, which do go through FDA approval.2
Ozempic is an FDA-approved injection made by Novo Nordisk. Its US label covers type 2 diabetes, plus lowering heart and kidney risks in adults with type 2 diabetes.5 Wegovy is the semaglutide brand approved for weight.
Can compounded semaglutide contain something different?
Yes. The FDA warns that some products sold by compounders may be salt forms, semaglutide sodium or semaglutide acetate, which it calls “different active ingredients.”1
It has also received reports of side effects, “some requiring hospitalization,” that may be linked to dosing errors with compounded injectable semaglutide.1 As of May 31, 2026, the FDA had 990 adverse-event reports associated with compounded semaglutide.1

Why is the FDA warning sellers?
On March 3, 2026, the FDA sent 30 warning letters to telehealth companies, for claims implying their compounded products were the same as FDA-approved ones, and for branding them with the telehealth company’s own name, which implies it made them.2
A month earlier, on February 6, 2026, the FDA said it would restrict the ingredients used in mass-marketed compounded GLP‑1s. It said companies may not claim these products are “generic versions or the same as drugs approved by FDA” or “clinically proven”.3
The semaglutide shortage ended on February 21, 2025, and pharmacies may no longer regularly make copies of approved products, apart from narrow exceptions.4 The FDA’s advice is to get a prescription and fill it at a state-licensed pharmacy.1 How to choose a provider safely is in Guide 7.
