What 'FDA-Approved' Actually Means (and Doesn't)
The phrase 'FDA-approved' gets attached to a lot of things it does not belong to. The FDA's own consumer page, titled 'Is It Really FDA Approved?', is the cleanest place to start. Approval means the agency has reviewed data, usually from clinical trials, and determined that a drug's benefits outweigh its known risks for its intended use. That determination is specific: a named drug, a named condition, a described population, and a labeled dose.
The mechanism is the New Drug Application. A company submits its trial results, manufacturing details and proposed label, and FDA reviewers assess them. The FDA's 1998 guidance on clinical evidence explains that effectiveness is normally demonstrated by adequate and well-controlled studies, typically more than one, though a single trial plus confirmatory evidence can suffice in some cases. Approval is the end of that review, not a general stamp of safety.
What approval does not cover is the longer list. The FDA does not approve dietary supplements before they reach the market; manufacturers are responsible for their own safety claims. It does not approve cosmetics, other than color additives. It does not approve compounded drugs, which are prepared by pharmacies for individual patients. It approves drugs, not facilities, so 'made in an FDA-registered facility' says nothing about whether the product itself has been reviewed. And it does not approve products sold as research chemicals for human use at all.
Approval is also tied to a labeled use. Semaglutide is a prescription medication approved for type 2 diabetes under one brand and for chronic weight management under another. Physicians can legally prescribe approved drugs beyond the label, but that is a separate concept covered in its own brief. The limit of 'FDA-approved' is that it is a judgment about a specific use in a studied population. Whether any approved drug is right for a given person is a physician's decision, not a label's.
