As of October 2, 2024, the FDA determined that the shortage of tirzepatide injection has been resolved. Tirzepatide is a glucagon-like peptide 1 (GLP-1) medication. It is the active ingredient in Mounjaro®, which is approved for the treatment of type 2 diabetes mellitus, and Zepbound®, which is approved for use in weight management. With increased demand, these commercially available tirzepatide products have been in shortage since 2022. The manufacturer recently confirmed that they have increased product availability and manufacturing capacity and are now prepared to meet the present and projected demand. However, there may still be disruptions in local supply as the products move from the manufacturer to distributors and pharmacies. Other GLP-1 medications, such as Ozempic®, Wegovy® and Trulicity®, are still in shortage.
During the shortage of commercially available GLP-1 medications, some compounding pharmacies have been able to legally produce unbranded versions of these drugs that contain the same active ingredients to help meet patient demand. However, the FDA highlights that compounded drugs are not approved by their agency. There are also legal restrictions on making compounded versions of FDA-approved drugs, and compounded drugs must meet conditions to quality for exemptions, namely sections 503A and 503B of the Federal Food, Drug and Cosmetic (FD&C) Act. As shortages resolve, production of compounded versions will likely be discontinued.
