The U.S. Food and Drug Administration (FDA) has issued important updates regarding GLP-1 receptor agonists, such as semaglutide (Ozempic®, Wegovy®) and tirzepatide (Mounjaro®, Zepbound®). These medications have gained widespread use for weight management, but concerns regarding their availability, safety, and the risks of compounded versions have led to increased regulatory oversight. The experts at DeanSilverMD.com are here to break down these updates, clarify what they mean for patients, and offer guidance on safe and effective weight loss strategies.
GLP-1 Drug Availability: What Has Changed?
In recent years, the popularity of GLP-1 drugs has led to significant supply shortages. However, the FDA has now confirmed that:
- Semaglutide supply issues have been resolved as of February 21, 2025.
- Tirzepatide shortages were officially resolved in December 2024.
While these updates are promising, localized supply disruptions may still occur as the distribution process normalizes. Patients should check with their healthcare providers and pharmacies to confirm availability before making any changes to their treatment plan.
The Risks of Compounded GLP-1 Medications
During previous shortages, many patients turned to compounded versions of semaglutide and tirzepatide. While compounding pharmacies serve an important role in healthcare, compounded GLP-1 medications are not FDA-approved and present certain risks:
- Dosing inconsistencies that can lead to underdosing or overdosing.
- Potential contamination due to lack of rigorous FDA oversight.
- Use of unauthorized salt forms (e.g., semaglutide sodium, semaglutide acetate), which have not been studied for safety or efficacy.
As supply stabilizes, the FDA is moving to restrict compounded versions and recommends transitioning back to FDA-approved GLP-1 medications whenever possible. The agency has received 455+ reports of adverse events related to compounded semaglutide and 320+ reports concerning compounded tirzepatide, underscoring the importance of using regulated medications.
FDA’s Enforcement Timeline for Compounded GLP-1 Drugs
To ensure a smooth transition, the FDA has temporarily allowed continued compounding under the following conditions:
- For state-licensed pharmacies and physicians (503A compounding): Compounded semaglutide is permitted until April 22, 2025.
- For outsourcing facilities (503B compounding): Compounded semaglutide is permitted until May 22, 2025.
After these dates, FDA enforcement against unauthorized compounding of GLP-1 drugs is expected to increase. Patients using compounded versions should consult their healthcare provider to discuss a transition plan.
How to Approach Weight Loss Safely and Effectively
While GLP-1 medications can be a helpful tool, they should be part of a comprehensive, medically guided weight loss strategy. Our wellness team at DeanSilverMD.com recommends the following evidence-based approach:
1. Prioritize Metabolic Health
GLP-1 medications work by regulating blood sugar and reducing appetite, but long-term success requires metabolic optimization. This includes:
- Balanced macronutrient intake (protein, healthy fats, and complex carbohydrates).
- Avoiding processed foods and excess sugar to stabilize insulin levels.
- Staying hydrated to support cellular function and digestion.
2. Maintain Lean Muscle Mass
Weight loss should not come at the expense of muscle loss, as this can slow metabolism and decrease overall strength. To preserve lean body mass:
- Incorporate resistance training at least 3–5 times per week.
- Ensure adequate protein intake (0.8–1.2g per pound of body weight).
- Get sufficient sleep to support muscle recovery and hormone regulation.
3. Address Underlying Health Issues
Many individuals struggling with weight loss have underlying health conditions that impact metabolism, such as:
- Thyroid dysfunction (e.g., hypothyroidism)
- Hormonal imbalances (e.g., insulin resistance, low testosterone)
- Chronic inflammation
Addressing these issues through lab testing and personalized medical guidance can optimize weight loss outcomes and improve overall health.
4. Monitor Cardiovascular and Digestive Health
GLP-1 medications can have effects on the heart and gastrointestinal system. Common side effects include:
- Nausea, vomiting, and diarrhea
- Heart palpitations or changes in heart rate
- Electrolyte imbalances
If you experience persistent or severe symptoms, consult your healthcare provider immediately. Proper monitoring ensures that these medications support health rather than cause unintended complications.
5. Be Cautious About Counterfeit GLP-1 Drugs
The FDA has issued warnings about counterfeit versions of Ozempic and other GLP-1 medications circulating in the market. These fake drugs may:
- Contain incorrect or harmful ingredients.
- Have too much, too little, or no active ingredient at all.
- Be sold illegally online without proper regulation.
To protect yourself, always obtain medications through a licensed healthcare provider and a verified pharmacy.
The Role of the FDA in Ensuring Safe and Effective Treatments
The FDA’s recent clarifications on GLP-1 drug availability and compounded versions reflect its commitment to balancing accessibility with safety. The agency will continue to:
- Monitor the national supply of GLP-1 medications.
- Investigate reports of adverse events linked to compounded and counterfeit drugs.
- Enforce regulations to protect patient safety.
Final Thoughts: The Future of GLP-1 Medications in Weight Management
The increasing availability of FDA-approved GLP-1 medications is a positive step for individuals seeking safe, effective, and medically supervised weight loss. However, these drugs should be seen as one component of a holistic health strategy that includes proper nutrition, physical activity, and medical oversight.
