Compounded Semaglutide: What It Is, and Why the FDA Has Issued Repeated Warnings
Compounded versions of semaglutide became widely available during brand-name shortages. Here's how they differ from FDA-approved products and what the regulatory record says.

'Compounded' semaglutide refers to versions of the drug prepared by compounding pharmacies rather than manufactured by Novo Nordisk. Compounding is legal in certain circumstances — traditionally to fill an individual prescription that isn't available commercially — and U.S. law allows compounding of a drug's active ingredient during an FDA-declared shortage.
Why compounded versions spread
Semaglutide products were on the FDA's drug shortage list for extended periods between 2022 and 2024, which opened the door for compounding pharmacies and telehealth platforms to offer compounded semaglutide, often at lower prices than brand-name Ozempic or Wegovy.
What regulators have said
The FDA has published multiple advisories about adverse events tied to compounded semaglutide, including dosing errors linked to the use of semaglutide salt forms (such as semaglutide sodium or semaglutide acetate) that have not been shown to be safe or effective, and are not the same active ingredient found in FDA-approved products.
The agency has also warned about counterfeit semaglutide entering the supply chain, in some cases through outlets that did not go through legitimate compounding channels at all. Once the FDA removed semaglutide injection products from the shortage list, the legal basis for most large-scale compounding narrowed significantly.
What this means for consumers
If a product is offered as 'semaglutide' outside of a pharmacy dispensing a prescription written against an FDA-approved product or a legitimate, state-licensed compounding pharmacy, treat the sourcing claims with skepticism. Questions worth asking before use: Is this dispensed by a licensed pharmacy? Is it tied to an actual prescription from a clinician who evaluated you? Is the active ingredient and concentration disclosed with a certificate of analysis?
