Instructions for Use, Warnings and Cautions in Nigerian Device Labelling

1. Key takeaways

Nigeria’s requirements for instructions and warnings are distributed across three layers: Regulation 24 of the Regulations (instructions for use), Regulation 25 (warnings and cautions) and Regulation 26 (displayed information must not mislead and must not be removed, altered or defaced); guideline VBM-R&RA-GDL-001-01 §7.3.1–§7.3.13 then sets out a 13-item list of what the instructions for use should contain, which serves as the direct checklist for writing an IFU.

The test for how much to write is not page count but three correspondences: correspondence with the intended use, correspondence with the risk classification, and consistency with the other information on the label. Regulation 26(2) adds a further red line — information on the label must not be removed, altered or defaced — which extends the duty into distribution and end use. A technically perfect IFU can still fail review if its performance statements drift from the label claims, so the three documents should be drafted together and reviewed as one package rather than sequentially by separate teams.

3. Expert insights

Insight one: the 13-item IFU list is minimum content, not recommended content. VBM-R&RA-GDL-001-01 §7.3.1–§7.3.13 lists item by item the information the instructions for use should contain. In practice we use it as a checklist: every item must be locatable at a specific page in the IFU. A missing item is not a matter of insufficient detail but of a non-conforming dossier, which proceeds directly into the compliance query stage — and a compliance query stops the clock (R&R-GDL-008-02 §12.8 / VBM-R&RA-GDL-001-01 §11.8), with the application automatically closed if unanswered for 90 days / 90 working days. Because the consequence of one missing item is a stopped clock, the page-mapping exercise should be done before submission, not during review.

Insight two: the adequate warnings standard of Regulation 25 is a dynamic standard linked to risk classification. Regulation 25 requires the label to state adequate warnings and cautions. Adequacy has an objective reference in the Nigerian framework: the higher the classification (Class C, Class D) and the greater the invasiveness (First Schedule, Rules 5–7), the more specific the warning content should be. Sterile devices must additionally be labelled per GMP §12.10, with no resterilisation and no reuse. A warning block copied unchanged across a whole catalogue therefore cannot be adequate for all products in it; warnings should be written per product family against its classification and invasiveness profile.

Insight three: instructions for small packages may accompany the device, but cannot be omitted. Where the outer packaging is too small to carry the complete instructions for use, the practical route is a package insert accompanying the device, rather than omitting content. We discussed the same fallback logic in article 23 — the carrier of the information may change; the content may not be reduced. This is worth restating because artwork teams under space pressure are often tempted to trim the insert text; the Regulations permit relocation, not abbreviation of substance.

Insight four: Regulation 26 extends the duty into distribution and the end user. Regulation 26(1): displayed information must not be misleading, and misleading information constitutes an offence, falling directly under the Regulation 48 penalties (natural persons: imprisonment of up to 1 year, or a fine of up to ₦800,000, or both; corporate bodies: up to ₦5,000,000). Regulation 26(2): no person may remove, alter or deface label information. This means importers, distributors and even end-use facilities are within scope, and the agreements with authorised representatives and local importers must include this obligation. The penalty figures make clear that label integrity is treated as a criminal-law matter, not a documentation preference.

Insight five: the IFU and advertising are two separate texts; do not mix them. The instructions for use are part of the labelling system; advertising requires a separate advertisement permit (Regulation 32), and registration does not equal an advertisement permit (Regulation 11.3 / §12.3). Copying performance statements from the IFU into promotional material triggers the claim restrictions of Regulations 41 and 42 — especially the words fast / immediate / instant / rapid, for which Regulation 51 gives quantified definitions: Fast = the claimed effect appears within 30 minutes; Immediate / Instant = within 10 seconds. Using these words requires corresponding performance study support, so the translation step from IFU to marketing copy is where most violations are born.

4. Practical recommendations

1. Write the IFU against the 13-item checklist item by item, noting the corresponding page number for each item to ease review location.
2. Scale warnings and cautions by classification and invasiveness, with extra weight for Class C and Class D and implanted devices.
3. Use a package insert for small-size packaging with no reduction of content.
4. Run a three-way consistency check across IFU, label and advertising text, especially performance statements and figures.
5. Insert the Regulation 26(2) obligation into importer and distributor agreements (no removal, alteration or defacement of labels).
6. Review advertising text separately, and prepare performance study evidence before using words such as fast, immediate, instant or rapid.

Each recommendation maps to a document the reviewer or inspector will eventually read. Preparing them together keeps the story consistent and removes the most common cause of stopped clocks in this area, which is inconsistency between documents rather than absence of content.

5. Verification checklist

• □ The IFU covers all 13 items of §7.3.1–§7.3.13 with page numbers noted.
• □ The label states adequate warnings and cautions (Regulation 25).
• □ Small-package devices use a package insert rather than reduced content.
• □ Displayed information has been checked as not misleading (Regulation 26(1)).
• □ Importer and distributor agreements include the duty not to remove, alter or deface labels (Regulation 26(2)).
• □ Advertising text and IFU performance statements have been reviewed separately, with quantified words supported by studies.
