The widespread popularity of semaglutide has led to a common misconception that all products containing the active ingredient are interchangeable. In reality, the landscape of semaglutide products is complex, comprising different FDA-approved brands and unregulated compounded versions. Understanding the key distinctions is essential for patient safety and effective treatment.
Understanding Semaglutide Brands
FDA-approved semaglutide products, such as Ozempic®, Wegovy®, and Rybelsus®, are manufactured by Novo Nordisk. These brands use the same active ingredient but are approved for different conditions and come in varying formulations and dosages.
- Ozempic®: A once-weekly injectable approved for Type 2 diabetes to improve blood sugar control and reduce cardiovascular risks. While sometimes used off-label for weight loss, its approved dosage differs from Wegovy®.
- Wegovy®: A once-weekly injectable specifically approved for chronic weight management in eligible adults and adolescents. It uses higher doses than Ozempic® and is prescribed alongside diet and exercise. Its indication also includes reducing the risk of cardiovascular events in certain overweight or obese adults.
- Rybelsus®: A daily oral tablet approved for adults with Type 2 diabetes. As the first oral GLP-1 receptor agonist, it requires specific administration instructions, such as taking it on an empty stomach.
Concerns with Compounded Semaglutide
Compounded semaglutide is not FDA-approved, and its safety, purity, and effectiveness are not guaranteed. The FDA has clarified that compounding pharmacies can no longer produce copycat versions once drug shortages are resolved. Risks associated with compounded semaglutide include:
- Ingredient Variations: Compounded versions may use different semaglutide salts not evaluated by the FDA.
- Lack of Oversight: They do not undergo the rigorous testing required for FDA-approved medications.
- Potential for Errors: There is a higher risk of incorrect dosing or contamination due to variable formulations.
Key Distinctions
Significant differences exist between FDA-approved brands and compounded versions regarding formulation, administration, dosage, consistency, and quality control. Inactive ingredients can also differ, which is important for individuals with allergies.
Semaglutide Product Comparison

Conclusion
While FDA-approved semaglutide products share the same active ingredient, they have distinct uses, formulations, and dosages. Compounded versions are unregulated and pose safety concerns.
