Unopened semaglutide pens should be stored in the refrigerator at 36F to 46F (2C to 8C)

These therapies aim to enhance WL and improve metabolic outcomes by engaging multiple hormonal pathways, with preclinical and early-phase clinical trials supporting their potential as next-generation obesity treatments [16,17,18,19,20,21,22,23]
