Where do wrong words hide on carton and container labels?

In the small, repeated text on the box and the bottle. Those panels are easy to proof by eye and easy to miss by meaning. A correctly spelled wrong word, the failure ContextRx documents on FDA DailyMed labels, passes spellcheck and can quietly contradict the prescribing information.

This is a how-to. For why label wording causes medication errors at all, see can label wording cause medication errors.

What the FDA guidance covers

The FDA's final guidance, Safety Considerations for Container Labels and Carton Labeling Design to Minimize Medication Errors (May 2022), is for human prescription drug and biological product sponsors, application holders and applicants. It gives principles and recommendations so that critical elements of the container label and carton labeling promote safe dispensing, administration and use. It carries the header "Contains Nonbinding Recommendations".

What goes on the principal display panel

The guidance defines the principal display panel as the panel most likely to be displayed to, presented to, shown to, or examined by the end user. It recommends the panel include this critical information:

Proprietary name, if there is one Established name or proper name Dosage form Product strength Route(s) of administration Warnings (if any) or cautionary statements (if any) Controlled substance schedule if the product is a controlled substance

The guidance says that information should be the most prominently displayed information on the panel. It also says that when information is printed on both the front and back panels, the critical information should be repeated on each side.

Why the small panels are risky for wording

Our view: repeated text is where a fix goes missing. A word corrected on the principal display panel can survive on a side panel, the back panel or the container label. Tight space and late artwork changes make that more likely, and a proofreader who has already read a line once tends to skim its repeat.

Matching the prescribing information

The guidance says information on the container label, the carton labeling, FDA-approved patient labeling and the prescribing information should be consistent, and that inconsistency can lead to confusion that can result in medication errors. It names product names, dosage forms, strengths, routes of administration, warnings or cautionary statements, and controlled substance schedule. It also asks for dosage terminology on the carton and container that is consistent with the prescribing information.

A wrong word on the box breaks that consistency, and spellcheck can't see it. For the prescribing information side, see PLR prescribing information wording.

How to read a carton for meaning

Practice advice:

• Do one pass per panel, and treat each repeat of a line as a new line.
• Read the route, strength, dosing and warning words aloud on each panel.
• Check each of those lines against the prescribing information for meaning, not just for matching characters.
• Do a final pass on the printed artwork, not only the text file.

Made-up example: a container label that should say "oral" prints "aural" on the side panel only. The principal display panel is correct, so a reviewer who stops there passes it.

Made-up example: a warning panel that should say "hypoglycemia" reads "hyperglycemia" on the carton but not in the prescribing information. Each word is real, and only a read for meaning catches the mismatch.

Is there FDA guidance on carton and container labels?

Yes. The FDA's final guidance from May 2022 sets principles and recommendations for container label and carton labeling design to minimize medication errors.

Does the carton label have to match the prescribing information?

The FDA's guidance says information on the container label, carton labeling and prescribing information should be consistent. A wrong word on the box can contradict the prescribing information without anyone noticing.

What goes on the principal display panel?

The guidance recommends the proprietary name if any, the established or proper name, dosage form, strength, route of administration, warnings or cautionary statements, and any controlled substance schedule.

How do I proofread a carton for meaning?

Practice advice: read each panel separately, read route, dose and warning words for sense, and check each repeated line, not just the first.
