The FDA has declared an end to the shortage of Novo Nordisk’s blockbuster drug semaglutide, threatening the ability for compounding pharmacies to make copies of Ozempic and Wegovy.

The U.S. Food and Drug Administration said on Friday there was no longer a shortage of Novo Nordisk's popular weight-loss and diabetes drugs, Wegovy and Ozempic, a declaration that will curtail widespread sales of cheaper copies made by compounding pharmacies.
