Wegovy and Zepbound are still hard to get. Knockoff versions from Noom, Ro, and others are filling in the gaps.

The U.S. Food and Drug Administration said Eli Lilly’s diabetes and weight-loss drugs marketed as Zepbound and Mounjaro are no longer in shortage signaling that the company has succeeded in expanding manufacturing.

A key study used in securing FDA approval for Wegovy as a lifetime medication for weight loss was based on patients using the drug continuously for about a year and 4 months and then stopping. It found that about two-thirds regained the weight they lost. A similarly designed study had comparable results for tirzepatide (Zepbound).

The San Francisco telehealth company had capitalized on the shortage by making copycat versions of popular brand-name GLP-1 medications. Shares of Hims & Hers Health fell almost 10% today following an announcement from the U.

A surge of alternatives to newly popular weight-loss drugs is facing its biggest test yet after the FDA warned companies against skirting regulatory standards to put them on the market now that shortages are waning.
