From the Guidelines
Compounded Wegovy is not recommended as a safe or effective alternative to FDA-approved Wegovy (semaglutide) for weight management due to concerns over quality, purity, and dosing. Wegovy is a prescription medication approved for chronic weight management that contains semaglutide, a GLP-1 receptor agonist that helps regulate appetite and food intake, as seen in the STEP trials which examined the efficacy of semaglutide 1. The FDA has specifically warned against using compounded versions of semaglutide, noting they have not been evaluated for safety, effectiveness, or quality.
Some key points to consider when evaluating the use of compounded Wegovy include:
- The potential for quality, purity, or dosing issues with compounded medications
- The lack of FDA evaluation for safety, effectiveness, or quality of compounded semaglutide
- The availability of FDA-approved options like Wegovy, Saxenda, or Zepbound, which have undergone rigorous testing for safety and efficacy 1
- The importance of speaking with a healthcare provider to determine the most appropriate medication based on specific health needs and insurance coverage
It's also important to note that GLP-1 receptor agonists, such as semaglutide, have been shown to decrease the risk of CVD events in adults with overweight or obesity without diabetes, as seen in a meta-analysis 1. Therefore, using FDA-approved medications like Wegovy can provide not only effective weight management but also potential cardiovascular benefits.

From the Research
Compounded Wegovy
- Compounded medications, such as compounded Wegovy, are prepared by compounding pharmacies to meet individual patients' needs that cannot be met by FDA-approved brand name or generic medications 2.
- The safety of compounded medications, including compounded Wegovy, can be a concern due to lesser regulatory oversight, which may lead to contamination or inaccurate potency 2.
- Compounded Wegovy should be prescribed only when an FDA-approved medication cannot be used, and the benefits outweigh the risks 2.
Semaglutide and Obesity
- Semaglutide, the active ingredient in Wegovy, has been shown to be effective in weight loss and improving cardiometabolic risk factors in adults with obesity 3, 4, 5.
- Semaglutide has demonstrated the largest weight loss of any obesity medication to date, with reductions of approximately 15% of initial weight at 68 weeks 5.
- The use of semaglutide for obesity treatment has been recommended by regulatory agencies, including the National Institute for Health and Care Excellence, for a maximum treatment duration of 2 years 4.
Safety and Efficacy
- The most common adverse events associated with semaglutide are gastrointestinal, including nausea and diarrhea, which are typically transient and mild-to-moderate in severity 3, 4.
- Semaglutide has also been associated with more serious adverse events, including pancreatitis, diabetic retinopathy, and severe allergic reactions 4.
- Further studies are needed to assess the long-term health benefits and safety of semaglutide for obesity treatment 4, 6.
