FDA Drug Labeling Requirements: What Foreign Manufacturers Must Include on US Packaging

Drug labeling in the United States is not a design decision — it is a regulatory requirement specified in federal statute and FDA regulation. A foreign manufacturer that produces a drug product for the US market and ships it with non-compliant labeling will find the product refused at the border or detained by the FDA upon arrival. The consequences extend beyond a single shipment: a pattern of labeling violations can result in import alerts that affect an entire product line. Getting labeling right before the first US shipment is considerably easier than correcting it after the product has already been refused.

OTC drugs: the Drug Facts panel

Over-the-counter drug products sold in the United States must display a Drug Facts panel formatted in accordance with 21 CFR 201.66. The Drug Facts panel must include the active ingredients with their purposes, the uses (indications) for the product, all required warnings and when-not-to-use statements, directions for use, a list of inactive ingredients, and the manufacturer's or distributor's name and contact information. The panel must use a specific font size minimum, appear in a box with defined formatting, and present information in the FDA-mandated sequence. A Drug Facts panel that omits required warnings or presents information in the wrong order is a labeling violation. The standard applies identically to foreign-manufactured and domestic OTC products.

Prescription drug labeling and the package insert

Prescription drugs require a package insert — the official prescribing information — that must comply with the content and format requirements in 21 CFR 201.56 and 201.57. For drugs approved under a New Drug Application or Abbreviated New Drug Application, the labeling text is the FDA-approved version on file; the manufacturer cannot deviate from the approved labeling without filing a prior approval supplement or other change control mechanism. Foreign manufacturers producing drugs for which there is an approved application must use exactly the FDA-approved labeling text. Deviation — even minor wording changes — constitutes a labeling violation that can trigger regulatory action.

Ingredient declarations and allergen labeling

Both OTC and prescription drug labels must declare inactive ingredients. For OTC drug products, inactive ingredients must be listed in alphabetical order. The FDA has also applied allergen labeling requirements from the Food Allergen Labeling and Consumer Protection Act to drug products where relevant — this is particularly important for drug products that contain color additives, flavors, or excipients derived from major food allergens. Foreign manufacturers that source excipients internationally must verify that inactive ingredient declarations accurately reflect what is actually in the product and that any allergen-relevant excipients are identified correctly.

Foreign language labeling and bilingual labels

The FDA requires that all mandatory labeling information appear in English. Foreign language text may appear on the label in addition to the English text, but the English labeling must be complete and compliant without relying on any foreign language text to supply required information. A label that presents Drug Facts or prescribing information only in a language other than English does not meet US requirements regardless of how well-formatted the foreign language version is. Many foreign manufacturers who sell the same products in multiple markets create separate label versions; the US version must be English-primary and must meet all FDA format requirements independently.
