The FDA has proposed excluding semaglutide, tirzepatide, and liraglutide from the 503B compounding bulks list — a move that would end access to affordable, compounded GLP-1 medications for millions of Americans. Physicians and patients have until June 30, 2026 to submit public comments.
On April 30, 2026, the FDA proposed to exclude semaglutide (Ozempic/Wegovy), tirzepatide (Mounjaro/Zepbound), and liraglutide (Victoza/Saxenda) from the 503B Bulks List. This list determines which drugs can be compounded in large quantities by outsourcing facilities.
The FDA's stated rationale is that these drugs are no longer in shortage. However, this ignores the critical role that compounding pharmacies play in providing affordable, accessible, and customized doses to patients who cannot afford or tolerate brand-name formulations.
If this proposal is finalized, millions of patients who rely on compounded GLP-1 medications for obesity, type 2 diabetes, and cardiovascular disease management could lose access to affordable treatment.
Brand-name GLP-1 medications cost $900–$1,400/month. Compounded versions are often 80–90% less expensive, making them accessible to patients without insurance coverage.
Compounding pharmacies provide customized doses and formulations for patients with specific medical needs that commercial products cannot address.
503B outsourcing facilities operate under strict FDA oversight and Current Good Manufacturing Practice (CGMP) standards, with an established safety record.
