Medical device labeling is not just a regulatory checkbox—it’s a lifeline for patients and healthcare professionals (HCPs). Every instruction, every warning, and every detail printed on a label, an Instruction for Use (IFU), or a digital interface is essential for ensuring that medical devices are used safely and effectively. Yet, what happens when a label is poorly translated, unclear, or inaccessible? The consequences can be catastrophic. A mistranslated dosage instruction, an unreadable warning, or missing accessibility features can lead to device misuse, and serious health risks.
This is why global manufacturers must not only comply with FDA and EU MDR/IVDR regulations but also ensure that their labeling is linguistically accurate, culturally adapted, and accessible to all users—including those with disabilities. This article explores the medical device labeling requirements in the U.S. and EU, the legal and patient safety risks of non-compliance, and the critical role of translation and accessibility in ensuring public health and regulatory success.

Medical Device Labeling in the United States
In the U.S., medical device labeling falls under FDA regulations (21 CFR Part 801 for medical devices and Part 809 for in-vitro diagnostics). These rules dictate how medical devices must be labeled to ensure safe usage by both healthcare professionals and patients.
What Must Be Included on a Medical Device Label?
A compliant label in the U.S. must feature:
- A Unique Device Identifier (UDI) for tracking and recalls.
- Manufacturer and distributor details for accountability.
- Clear and accurate usage instructions for both professionals and patients.
- Indications for use, warnings, and contraindications to prevent misuse.
- Storage conditions and expiration dates to ensure device efficacy.
What is UDI?
The Unique Device Identifier (UDI) is a system used to uniquely identify medical devices throughout their distribution and use. It is a key element in device traceability, recall management, and patient safety initiatives. The UDI consists of:
- A Device Identifier (DI): A mandatory, fixed portion that identifies the labeler and device model.
- A Production Identifier (PI): A variable component that includes information like lot number, serial number, expiration date, or manufacturing date.
The FDA requires UDI labeling on most medical devices, and the EU MDR mandates UDI compliance for devices sold in Europe. Proper implementation of UDI reduces medical errors, enhances supply chain security, and improves post-market surveillance. Labels must be in English, but the FDA acknowledges the importance of multilingual labeling—especially for devices marketed in areas with large non-English-speaking populations.
Why is Medical Device Label translation and accessibility so important?
Consider a patient using an insulin pump where the translated Instructions for Use (IFUs) contain an incorrect interpretation of the term “units.” Such an error could result in improper dosage administration, potentially leading to adverse health effects. Or consider a non-English-speaking caregiver trying to operate a dialysis machine, but the instructions are only in English. If they misunderstand the warnings, the patient could suffer serious harm. For these reasons, the FDA encourages accurate, patient-friendly translations and promotes the use of digital labeling (e-labeling) for easier multilingual access.
Beyond translation, accessibility is critical. Medical device labeling should consider:
✅ Braille labels for blind or visually impaired users.
✅ Screen-reader-compatible e-IFUs for digital accessibility.
✅ Clear, easy-to-understand wording to avoid misinterpretation.
While these elements are not always mandatory under FDA regulations, failing to provide accessible labeling can lead to misuse, product recalls, and legal consequences.
Medical Device Labeling in the European Union: MDR & IVDR Regulations
Europe has some of the strictest medical device labeling regulations in the world, requiring highly accurate translations across multiple languages and comprehensive accessibility measures. The EU MDR (Medical Device Regulation 2017/745) and IVDR (In Vitro Diagnostic Regulation 2017/746) set rigorous standards for labeling, requiring that devices be safe, effective, and usable in all 27 EU member states.
What Makes EU Labeling Different?
Unlike the U.S., where English labeling is dominant, EU MDR and IVDR require translations into the official languages of every country where the device is sold—which can mean up to 24 different languages.
Key EU Labeling Requirements:
✔️ Translations of labels, IFUs, and e-labeling in multiple languages.
✔️ CE Marking & Notified Body Number to confirm compliance.
✔️ UDI for tracking and safety monitoring.
✔️ Mandatory use of standardized medical symbols (ISO 15223-1).
✔️ Braille labeling for patient-facing devices, ensuring accessibility.
IVDR regulations apply to in-vitro diagnostic devices used by both patients and healthcare professionals, ensuring that all critical test data and operation instructions are clear, accessible, and accurately translated.
Real Consequences: When Poor Translation Leads to Medical Errors
Mistranslations in medical device labeling are not hypothetical—they have led to real-world medical errors, product recalls, and legal actions. For example, the mistranslation of “reverse-pipetting” in laboratory instructions from English into German resulted in improper pipetting techniques in diagnostic procedures. If an inexperienced translator renders “reverse-pipetting” literally, it could be translated as “use the pipette backwards,” leading to confusion and errors in laboratory settings. This example highlights why medical device translations must be handled by certified specialists who understand both language nuances and medical contexts.
Prioritizing Accurate, Accessible and Compliant Medical Device Labeling
Medical device labeling is not just a regulatory formality—it’s a critical factor in patient safety, healthcare efficiency, and global compliance. Manufacturers must invest in high-quality translation, accessibility strategies, and digital labeling solutions.
Key Takeaways:
✅ U.S. FDA regulations prioritize English labeling but encourage accessibility.
✅ EU MDR/IVDR mandate translations into up to 24 languages and require Braille.
✅ Poor labeling can result in medical errors, legal actions, and product recalls.
✅ Accessibility is no longer optional—Braille, large-print IFUs, and e-IFUs are essential.
