eIFU Translations & Localizations: What Organizations Need to Know

Under the EU Medical Device Regulation (MDR), transitional deadlines for legacy devices are approaching, with higher-risk and implantable devices required to comply by December 31, 2027, and many lower-risk legacy devices by December 31, 2028. Manufacturers of in vitro diagnostic (IVD) medical devices should also consider the requirements of the In Vitro Diagnostic Regulation (IVDR), where equivalent multilingual documentation obligations apply. Now is the time to review your multilingual documentation strategy.

While traditional paper Instructions for Use remain widely used across the medical device industry, electronic Instructions for Use are becoming increasingly common as manufacturers adopt digital documentation solutions where regulations allow. An eIFU is far more than a digital version of a printed IFU – it is a living regulatory document that must remain accurate and accessible as products and regulations evolve.

In this guide, we'll explain why eIFU translation and localization matter, the key compliance and usability considerations, and how working with a specialist life sciences partner like Conversis can help reduce risk while supporting global regulatory compliance.

What eIFU Translation & Localization Actually Involve

Although the terms are often used interchangeably, translation and localization play different roles in producing both compliant and user-friendly eIFUs:

• Translation focuses on converting an eIFU into another language while preserving its technical accuracy, clinical meaning, and regulatory intent.
• Localization goes further by adapting the translated content for the target market. This can include terminology, formatting, symbols, units of measurement, dates, and other market-specific conventions, as well as ensuring navigation and other interactive elements function correctly across electronic documents.

The intended audience also matters. eIFUs written for healthcare professionals may require different language and presentation than those intended for patients, while still communicating the same essential information.

Ultimately, effective eIFU localization ensures every version is compliant and consistent, providing users with the same level of understanding, regardless of the language or market.

Why eIFU Accuracy Matters for Safety, Not Just Compliance

Accurate eIFUs are essential for both regulatory compliance and the safe, effective use of medical devices. Translation issues can delay regulatory submissions and market entry if documentation requires correction or re-submission, while also increasing the burden on internal regulatory and quality teams.

Because eIFUs often contain highly-technical information, even seemingly small wording changes can have disproportionate consequences. An ambiguous instruction or incorrectly translated safety warning may affect clinical decision-making or patient outcomes, while also exposing manufacturers to complaints or regulatory action.

This is why quality assurance is an essential part of the translation and localization process. Thorough linguistic review, technical validation, and consistency checks help ensure every language version communicates the same information with the same level of clarity, reducing risk for both users and manufacturers.

Regulatory Requirements Across EU & US Markets

Language requirements for eIFUs vary by market, making compliance a key consideration for manufacturers selling internationally. The use of eIFUs is itself regulated and depends on factors such as device type, intended users, and the markets in which a device is placed. Manufacturers must therefore understand not only when eIFUs are permitted, but also the language and documentation requirements that apply in each region.

European Union

The use of eIFUs is governed by the EU Medical Device Regulation (MDR) (Regulation (EU) 2017/745) alongside Commission Implementing Regulation (EU) 2021/2226, which sets out the conditions under which electronic Instructions for Use may be provided. In addition, Article 10(11) of the MDR requires manufacturers to provide information supplied with a device in the official language(s) determined by each Member State where the device is made available. Similar multilingual documentation requirements also apply to manufacturers operating under the In Vitro Diagnostic Regulation (IVDR) (Regulation (EU) 2017/746).

Where electronic instructions are permitted, manufacturers are responsible for ensuring every language version remains accurate and up to date throughout the product lifecycle.

United States

In the United States, medical device labeling requirements are governed by 21 CFR Part 801, with English generally required unless specific exemptions apply. Depending on the intended users, healthcare setting, or distribution strategy, manufacturers may also choose to provide additional language versions to improve accessibility and reduce the risk of misunderstanding.

Managing Global Compliance

Beyond the EU and US, language requirements differ significantly between countries. Some markets require documentation in one or more official languages, while others have additional formatting or labeling expectations. As regulations continue to evolve, manufacturers should monitor local requirements carefully and ensure every eIFU remains accurate, compliant, and consistent across all markets.

What Regulatory-Compliant eIFU Localization Looks Like in Practice

Achieving regulatory compliance requires more than translating content accurately. A well-managed localization process helps ensure every eIFU remains traceable and fit for purpose throughout the product lifecycle.

Terminology Management

Approved glossaries and translation memories help maintain consistent medical and technical terminology across every language, reducing the risk of conflicting instructions or interpretations.

Version Control

As regulations and safety information evolve, every localized eIFU must be updated in line with the latest approved source version. Robust version control helps prevent outdated or inconsistent documentation from reaching users.

Validation & Quality Assurance

Depending on the device, market, and level of risk, additional review processes – such as independent linguistic review, in-country validation, or back translation – may be appropriate to verify that translated content accurately reflects the original intent.

Digital Formatting

Localized eIFUs should retain the usability of the source document. Navigation, tables, symbols, images, and other interactive elements should function correctly and present information clearly across every language version.

Accessibility considerations are also important, particularly where eIFUs are delivered digitally. Documents should remain easy to navigate and understand for all intended users, including healthcare professionals and patients.

Balancing Consistency With Local Requirements

Global consistency is essential, but so is meeting local expectations. Regulatory-compliant localization harmonizes terminology and messaging across markets while adapting language and conventions where required to satisfy regional regulations and improve user understanding.

Together, these processes help manufacturers reduce compliance risk while ensuring every user receives accurate and reliable instructions, regardless of language or location.

Common Translation Issues Medical Device Teams Should Watch For

Even organizations with robust quality systems can encounter challenges when managing multilingual eIFUs. Many issues arise not from the translation itself, but from the processes surrounding it:

• Treating Translation as a Final Step: Planning eIFU translation from the start helps keep multilingual documentation aligned with product development and regulatory timelines. Leaving translation until the end can increase costs and leave little time for thorough review before submission.
• Relying on General Translation Expertise: Medical device documentation requires an understanding of technical terminology, regulatory language, and the intended clinical context. Without this expertise, even accurate-sounding translations can introduce ambiguity or risk.
• Poor Version Control: When source documents are updated, every localized eIFU must be revised accordingly. Failing to synchronize changes across all languages can result in inconsistent instructions and potential compliance issues.
• Overlooking Local Requirements: A direct translation may not satisfy market-specific regulatory expectations. Local language requirements and terminology preferences should both be considered during localization.
• Inadequate Review Processes: Without robust linguistic and technical review, errors and inconsistencies are more likely to go unnoticed. Clear approval workflows help ensure every language version is accurate before publication.
• Inconsistent Terminology: Using different translations for the same terms across products or document versions can confuse users and undermine consistency. Maintaining approved glossaries and terminology databases helps create a more reliable user experience.
