Buying and sourcing
FDA-approved describes a product and a use, not a molecule
On this page
An FDA approval attaches to a specific product from a specific manufacturer, for a specific use, with a specific label.
It does not attach to the molecule in general, and it does not travel to other products containing the same ingredient.
So a compounded, imported or research-labelled version of an approved molecule is not covered by that approval in any respect.
19 of the 68 compounds tracked here have an approved product; 3 of those products are no longer marketed.
This page explains what an FDA approval covers and what it does not, using the approval records for the compounds tracked here. It is not legal advice, not medical advice, and contains no dose, schedule or route.
What is actually being approved
An approval is granted on an application covering a finished product: this ingredient, at this strength, in this presentation, made by this manufacturer under these controls, for this use, with this label. Every one of those elements is part of what was reviewed.12
That is why the same molecule can require several approvals. Semaglutide appears under six brand entries because each product and indication was reviewed separately.2
Four things it does not cover
- A different product containing the same ingredient. That needs its own application.
- A use the label does not describe. Clinicians may prescribe off-label; the approval does not extend to it.
- A compounded preparation. Compounded drugs are not FDA-approved products.
- A version bought outside the regulated supply chain, whatever the label says.234
The third of those is the one that causes the most confusion in this category, because a compounded preparation may contain the same active ingredient as an approved product and is nonetheless not covered by its approval at any point.4
Off-label is not a loophole
Prescribing an approved product for an unapproved use is lawful and routine. It happens because a clinician judges it appropriate, not because the approval stretched to cover it.3
So off-label use sits on the clinician's judgement rather than on the regulator's review. That is a meaningful difference in what stands behind the decision.3
How to read an approval claim
The checkable version of the claim has an application number. With it you can see the approval date, the indication, the products under it and their marketing status, all in the public database.2
Without one, FDA-approved is doing rhetorical work rather than factual work. It is not necessarily false; it is simply not yet a statement anyone can verify.2
Common questions
Is an approved generic the same as the brand?
A generic is approved on its own application demonstrating equivalence to the reference product. It is separately approved, not covered by the brand's approval.
Does approval mean the FDA tested the drug?
No. The sponsor runs the studies and submits the data; the FDA reviews it, inspects manufacturing, and decides. Review is not the same as independent testing.
What does research use only mean on a label?
It signals a product not intended or reviewed for human use. It is a statement about what the seller is claiming, not a regulatory category conferring any assurance.
