An evidence-aware overview of compounded semaglutide, how it differs from FDA-approved semaglutide products and what consumers should verify.
Definition
Compounded semaglutide is a patient-specific preparation made by a compounding pharmacy under applicable compounding rules. It is not an FDA-approved finished drug product.
It is not simply 'generic Wegovy'
A compounded preparation should not be represented as an FDA-approved generic equivalent. FDA has specifically warned about misleading equivalence claims.
Dosing-error concern
FDA has reported adverse events, including some hospitalizations, associated with dosing errors involving compounded injectable semaglutide.
