Facing pages must be clearly marked as one continuous advertisement

AI-verifiedwarningBinding lawRaised as a question — a person decides

Rule

In a print advertisement spanning two facing pages where one page carries the side-effect and contraindication information, failure to provide adequate emphasis (e.g., color scheme, borders, headlines, or copy extending across the gutter) for the fact that the two pages are part of the same advertisement may render the advertisement lacking in fair balance or otherwise misleading. 21 CFR 202.1(e)(7) enumerates this as one of a list of factors under which an advertisement may be false, lacking in fair balance, or otherwise misleading — it is not an independent mandate, and a finding under it is presumptive rather than conclusive.

Check

Flag facing-page spreads with a separated risk-information page that lack a clear visual linkage device (color scheme, borders, headlines, or gutter-spanning copy), as a possible fair-balance deficiency for human review.

Escalate when

Always escalate: adequacy of the linkage device is a matter of layout judgment, and because 21 CFR 202.1(e)(7) findings are framed as 'may be' rather than mandatory, a reviewer must confirm whether the absence of a linkage device actually renders the advertisement lacking in fair balance or misleading in context.

Where this comes from

21 CFR 202.1(e)(7)(ix). The highlighted words are quoted exactly; a script confirms they appear in the source before the rule can be published.

…ess or safety of the drug. (viii) Fails to present information relating to side effects and contraindications with a prominence and readability reasonably comparable with the presentation of information relating to effectiveness of the drug, taking into account all implementing factors such as typography, layout, contrast, headlines, paragraphing, white space, and any other techniques apt to achieve emphasis. (ix) Fails to provide adequate emphasis (for example, by the use of color scheme, borders, headlines, or copy that extends across the gutter) for the fact that two facing pages are part of the same advertisement when one page contains information relating to side effects and contraindications. (x) In an advertisement promoting use of the drug in a selected class of patients (for example, geriatric patients or depressed patients), fails to present with adequate emphasis the significant side effects and contraindications or the significant dosage considerations, when dosage recommendations are included in an advertisement, especially applicable to that selected class of patients. (xi) Fails to present on …

Reviewer's reasons
- The quote is verbatim from 21 CFR 202.1(e)(7)(ix) and the locator matches; the substance of the rule (visual linkage across a facing-page spread when one page carries side effects/contraindications) does track the cited text.
- Overstated: the cited subparagraph falls under the heading '(7) Advertisements that may be false, lacking in fair balance, or otherwise misleading. An advertisement MAY BE false, lacking in fair balance, or otherwise misleading ... if it:'. The regulation lists (e)(7)(ix) as a factor that may render an ad misleading, deliberately distinguished from the categorical (e)(6) list. The rule rewrites this as an absolute obligation ('adequate visual cues ... must indicate'), which is stronger than the source.
- Scope gap: 21 CFR 202.1 governs prescription-drug advertisements (section title and the repeated section 502(n) references in the source). applies_when limits to promotional/print but does not limit to prescription drug advertising. The print limitation is itself well justified by the 'facing pages'/'gutter' language.
- determinism 'judgment' is correct: 'adequate emphasis' turns on layout impression and prominence, not presence/absence; the escalate condition is aligned.
- authority 'binding' is correct: this is a codified federal regulation, not guidance.
- Atomic: a single requirement; the listed devices (color scheme, borders, headlines, gutter-spanning copy) are the regulation's own illustrative examples, not separate independently checkable obligations.
- Severity 'warning' is defensible and consistent with the (e)(7) 'may be' framing; it should not be escalated.
- Category 'fair-balance' is appropriate given the subparagraph's placement and its concern with emphasis of side-effect and contraindication information.

Reviewer's reasons
- The quote is genuine and sits in (e)(7)(ix), but (e)(7) is introduced as 'Advertisements that MAY be false, lacking in fair balance, or otherwise misleading' — a list of factors that may render an ad misleading, not a list of absolute requirements. Contrast (e)(6), which states that an ad 'is false, lacking in fair balance, or otherwise misleading ... if it' does the listed things.
- Overstated: the rule statement converts the (e)(7) 'may be' formulation into a flat obligation ('adequate visual cues ... must indicate that the pages are one continuous advertisement'). This is the classic failure of writing a conditional/indicative factor as a mandate, and it would be shown to reviewers as a hard requirement of the regulation when the source does not make it one.
- The substance is otherwise faithful: the source does tie the emphasis expectation to the specific situation where one page of a facing-page pair contains the side-effect and contraindication information, and it names the same example devices (color scheme, borders, headlines, copy extending across the gutter).
- Atomic: one checkable condition (adequate emphasis linking the two facing pages).
- Determinism 'judgment' is correct — 'adequate emphasis' turns on prominence and layout impression.
- Authority 'binding' is correct (regulation).
- Severity 'warning' rather than 'blocker' is well matched to the 'may be misleading' framing.
- applies_when (promotional, print) is justified rather than invented: facing pages and a gutter presuppose a printed multi-page advertisement, and the (e)(7) list applies to advertisements, i.e. promotional matter.
- Locator 21 CFR 202.1(e)(7)(ix) is correct.

Reviewer's reasons
- The quote is the operative text of 21 CFR 202.1(e)(7)(ix), a substantive enumerated factor, not an example, definition or preamble; the locator matches the quoted subparagraph.
- The rule statement preserves the 'may be false, lacking in fair balance, or otherwise misleading' framing of the (e)(7) chapeau and expressly says it is not an independent mandate, so it is not written as a stronger obligation than the source creates.
- The applies_when limit to print is justified by the source's own terms: 'two facing pages', 'gutter', and page-level emphasis devices are print-specific; the limit is drawn from the text rather than invented.
- 'Adequate emphasis' for the linkage between facing pages turns on layout impression, so 'judgment' is the correct determinism; the check flags candidates for human review rather than asserting a violation.
- Authority 'binding' is correct — this is a codified FDA regulation. Severity 'warning' is defensible given the presumptive, non-conclusive character of (e)(7).
- Single requirement (visual linkage device for a facing-page spread whose risk information sits on one page); no independently checkable requirements are bundled.
