FDA Proposes Permanent 503B Compounding Ban for Semaglutide, Tirzepatide & Liraglutide
Verified May 8, 2026: On April 30, FDA proposed permanently removing semaglutide, tirzepatide, and liraglutide from the 503B outsourcing bulk list — forever, not just during shortage enforcement. Public comment closes June 29, 2026. If finalized, no 503B pharmacy could bulk-compound these GLP-1 drugs in the future, even if a new shortage is declared. 503A patient-specific compounding under medical-necessity remains unaffected.
