There are many drugs on the market created in a myriad of ways with some manufacturing processes less regulated, and therefore more dangerous, than others. One such method is called human drug compounding. Compounding occurs when a licensed physician or person under the supervision of a licensed pharmacist combines ingredients to form a medication designed for a specific patient. Compounded drugs can be incredibly important: they fill the gap for patients requiring specific strengths or dosages not available on the commercial market, they can remove allergens from drugs for patients with allergies, and they can change the form of the medication for patients that may have unique needs. It is also possible to create compound versions of the drugs on the FDA’s drug shortages list if the drug meets certain requirements.
However, compounded drugs also come with a great risk: they are not FDA-approved. The Food and Drug Administration (FDA) is tasked with protecting the public health by approving drugs based on safety, efficacy, and security standards. The FDA has a robust drug approval process through which most drugs in the U.S. must pass, but compounded drugs are not subject to this process. This means that a compounded drug may not meet quality or safety standards as a traditional commercially marketed drug would.
One recent area where compounded drugs have become increasingly popular: GLP-1 drugs. A GLP-1, or glucagon-like peptide-1, is a hormone that is naturally produced in the body. Companies have figured out how to develop GLP-1s into drugs, initially to treat type 2 diabetes and more recently for weight management.
In a statement by the FDA released on February 6, 2026, the FDA announced it intended to take “decisive steps to restrict” the active ingredients of GLP-1s that are intended to be used in non-FDA approved compounded drugs in order to “safeguard consumers from drugs for which the FDA cannot verify quality, safety, or efficacy,” as the selling of non-FDA approved drugs is a violation of the Federal Food, Drug, and Cosmetic Act. The statement also addressed misleading advertising and marketing of companies claiming that their non-FDA approved compounded drugs were simply generic versions of FDA-approved drugs.
Hims & Hers, referenced in the letter, has been in the headlines recently. Novo Nordisk, maker of the Wegovy pill and injections, has filed a lawsuit against Hims & Hers, a telehealth provider, for marketing compounded versions of its drugs, claiming patent infringement. Recent statements by Novo Nordisk’s general counsel for global legal, IP, and security called into question the safety and risks associated with Hims & Hers products, referring to the lack of FDA regulation for compounded drugs. This is not the first legal and regulatory issue faced by a GLP-1 manufacturer. In 2024, Eli Lilly’s weight loss drugs Zepbound and Mounjaro had their active ingredient tirzepatide regularly compounded before the FDA took it off the drug shortages list. The problems are likely just beginning. Between 2019 and 2024, Medicare Part D claims increased from 4.8 million to 21.8 million for GLP-1s. In addition to Novo Nordisk’s patent suit, there is also ongoing multidistrict litigation against Novo Nordisk and Eli Lilly by patients alleging loss of eyesight from their weight loss drugs. With the explosion of GLP-1s, it is likely that more issues will arise.
