Important Current Status Update: As of March 19, 2025, the FDA has ended enforcement discretion for compounded tirzepatide.

Key Takeaways

Compounded tirzepatide is no longer available as of March 2025 due to FDA enforcement policy changes
The FDA determined the tirzepatide shortage has been resolved, ending the legal basis for most compounding
Very limited exceptions may exist for specific medical needs under strict conditions
Only FDA-approved commercial versions (Mounjaro or Zepbound) are now legally available for most patients

Can Tirzepatide Be Compounded?

Pharmaceutical compounding is the art and science of creating personalized medications tailored to meet specific patient needs. This practice has been around for centuries and continues to play a vital role in modern healthcare.

During the shortage period (2022-2025), tirzepatide could be compounded. The FDA allowed compounding tirzepatide when commercial products were unavailable due to shortage conditions. This involved creating customized versions of the medication in compounding pharmacies with adjustments in dosage, form, or ingredients that might not be available in commercial products like Mounjaro or Zepbound.

Current Status: The FDA has officially determined that the shortage of tirzepatide injection products is now resolved as of December 19, 2024. With the shortage resolved, the legal basis for most compounding has ended. There are still exceptions available for compounding but are rare.

What is compounded Tirzepatide?

During the shortage period, compounded tirzepatide was a customized version of tirzepatide, the active ingredient in medications like Mounjaro and Zepbound. It was created by licensed pharmacists in compounding pharmacies to meet specific patient needs when commercially available products were unavailable.

Compounded tirzepatide typically contained:

Tirzepatide: The active ingredient that may support weight loss efforts
A diluent: A substance used to dissolve the tirzepatide
Potentially other ingredients: Depending on the specific formulation

Some compounded versions included additional ingredients like vitamin B12, leading to products labeled as “compounded tirzepatide with B12.”

Key Differences From Commercial Tirzepatide

The differences between compounded and commercial tirzepatide are significant:

Regulatory oversight: Commercial tirzepatide products are FDA-approved, while compounded versions were not
Quality control: FDA-approved medications undergo stringent quality control processes that were not required for compounded drugs
Clinical evidence: FDA-approved products have extensive clinical trial support, while compounded formulations lacked this evidence
Manufacturing standards: Commercial products are manufactured under strict FDA Good Manufacturing Practice standards

Is Compounded Tirzepatide Safe?

Quality and Safety Issues: Experts have highlighted the potential risks associated with compounded GLP-1 receptor drugs like tirzepatide. These risks include variability in drug potency, contamination, and other safety concerns.

FDA’s Safety Position: While compounded medications are regulated and inspected to some extent, they do not go through the same rigorous testing and quality assurance as FDA-approved drugs. As Peter Ax, founder and CEO of UpScriptHealth, stated, “When you purchase a drug that is compounded, there’s inherently more risk compared to one manufactured in an FDA-approved facility”.

What This Means for Patients

If You Were Previously Using Compounded Tirzepatide:

If you relied on compounded Tirzepatide, you’ll need to discuss alternative options with your healthcare provider. You may need to switch to an FDA-approved GLP-1 and GIP medication.

Important Steps to Take:

Consult with your healthcare provider about FDA-approved alternatives
Discuss insurance coverage options for commercial products
Review potential cost-saving programs offered by manufacturers
Explore patient assistance programs if cost is a concern

Cost Considerations: For many, compounded versions were more affordable. Brand-name GLP-1 and GIP medications can be expensive. However, both Eli Lilly and Novo Nordisk now offer direct-pay programs and manufacturer coupons that may help reduce costs.

Current FDA-Approved Options

Available FDA-Approved Tirzepatide Products:

Mounjaro® (tirzepatide): FDA-approved for type 2 diabetes management
Zepbound® (tirzepatide): FDA-approved specifically for chronic weight management

Both products have undergone extensive clinical trials demonstrating safety and efficacy, are manufactured under strict FDA oversight, and have consistent quality control standards.

Very Limited Exceptions That May Still Exist

Rare Circumstances Where Compounding Might Still Be Permitted:

Pharmacies may still compound tirzepatide under Section 503A if a physician determines a patient requires a significant modification, such as an alternative formulation due to an allergy. However, this justification must be explicitly documented on the prescription.

Important Requirements for Any Exception:

Must involve significant medical necessity
Requires detailed physician documentation
Cannot be “essentially a copy” of commercial products
Must meet strict quality and safety standards

Conclusion

The era of widely available compounded tirzepatide has ended as of March 2025, following the FDA’s determination that the drug shortage has been resolved. This development serves as a reminder of the importance of regulatory oversight in ensuring drug quality and patient safety.

Key takeaways:

Compounded tirzepatide is no longer legally available for most patients
FDA-approved products (Mounjaro® and Zepbound®) are now the primary options
Very limited exceptions may exist for specific medical circumstances
Professional medical guidance is essential for transitioning to approved alternatives
