Open the record behind the claim.

Use an approval record for an approval claim.

The U.S. Food and Drug Administration, or FDA, keeps product records. Ask the service to show the record for the exact medicine and form.

National Drug Code is shortened to NDC. This number identifies a drug’s listing in a directory.

As of September 2026, an NDC number does not mean the FDA approved a product.

Use that number to find the listing. For approval, request the FDA record that covers the particular medicine.

Registration is another separate check.

Putting a facility on the FDA’s register does not give it or its products approval, as of September 2026.

Health care providers, including doctors’ offices, do not receive FDA approval, the agency says.

Ask what being on that register tells you. Check the treating person’s state licence as well as the medicine’s approval.

Look for updates to a government warning.

The FDA’s warning-letter search lets you find the company’s replies and later letters about the concerns raised.

Search by company name.

Open the warning letter and look for linked replies or later letters.

Ask the FDA to explain any later letter you cannot understand.

A warning letter records the FDA’s concerns when it was written. It gives no final decision; later letters may alter the status of the matter.

A company with no letter may simply not have been reviewed.

Look for later material. Do not treat an empty search result as a full check of a business.
