For contextual class comparisons, the eMC SmPCs for semaglutide (Wegovy/Ozempic) and tirzepatide (Mounjaro) provide authoritative information on hypersensitivity and injection site reactions associated with approved GLP-1-based agents, and are relevant reference points for clinicians managing similar symptoms in patients receiving retatrutide in a trial setting
During shortages of Wegovy, Ozempic, Mounjaro, and Zepbound, the FDA exercised temporary enforcement discretion , allowing compounding pharmacies to help meet patient demand. Once manufacturing stabilized: Semaglutide injection products were removed from the FDA Drug Shortage List Tirzepatide injection products were formally declared resolved Compounding reverted to pre-shortage federal and state limits Broad, shortage-based compounding is no longer allowed in 2026
