Brand-name injectable drugs like Ozempic, Wegovy, Mounjaro, and Zepbound, despite their high cost (about $800-$1,000 per month) and limited insurance coverage for weight loss, have become billion-dollar sellers due to their effectiveness in weight loss, blood sugar control, and heart disease risk reduction. The FDA resolved a 2022 shortage of the active ingredient in Mounjaro and Zepbound, but patents on semaglutide and tirzepatide extend until 2033 and 2036, respectively, preventing generic versions. Non-brand alternatives, including dietary supplements and compounded drugs, pose risks due to lack of regulation and testing. Compounding pharmacies offer custom versions but are less regulated than commercial manufacturers. Peptide companies exploit loopholes to sell unapproved versions, often without prescriptions, leading to potential health hazards. Eli Lilly and Novo Nordisk have introduced lower-priced alternatives, and future market entrants may further reduce costs.
