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.

In December, the FDA declared that shortages of treatments Zepbound and Mounjaro from another drugmaker, Eli Lilly and Co., also had been resolved. Zepbound is approved to treat obesity and Mounjaro is approved for diabetes. They use the same active ingredient, tirzepatide.

The FDA’s decision will threaten the ability of compounding pharmacies to make far cheaper, unbranded versions of the injections over the next few months.
