How IFU translation errors can weaken safety information, and what to check in terminology, symbols, source revisions and documented review.
View the file review example ↓View references (2) ↓The IFU is a safety control
Instructions for use communicate intended use, warnings, contraindications and handling steps. They are one part of a device’s risk controls; they do not replace safe design or other required protective measures.
When the translated version weakens a warning or blurs a contraindication, the control is weaker in that market than the risk file assumes — while the risk file still claims it is in place.
Where exposure comes from
If a user in a given market received instructions that did not convey what the source conveyed, the adequacy of the warning in that market can be questioned. That is a materially worse position than a translation dispute.
We are describing exposure, not a legal outcome — liability depends on jurisdiction and facts. Treat this as a reason to involve your legal and quality functions in labelling translation, not as legal advice.
A concrete example is FDA’s LifeGlobal recall record: the Spanish IFU stated five minutes where the English source stated five seconds. This supports checking quantities and units against the source; it does not establish a universal legal outcome for every translation error.

Review status: questions to confirm
Preserve safety meaning
Compare the action, quantity, unit and accompanying warning with the approved source.
Flag unresolved wording
Keep questions visible for the product or regulatory owner rather than silently deciding them.
Identify the version
Record the source revision, target language and review status for the intended market.

Medical-device registration files and technical specifications, in volume.
The Nipro record covers Chinese-to-English medical-device registration files and technical specifications. It is related documentation experience, not an inbound-Chinese IFU project or the source of this illustrative review sheet.
Identify the actual source and target languages, device and document set, approved IFU and linked-label revisions, intended market and readers, and the owner for product or regulatory questions. Confirm review scope, return files and deadline. Start with a non-sensitive inventory or redacted representative page.
What reduces it
Reviewers with clinical or biomedical background rather than general linguists. Terminology locked against your approved labelling. Consistent handling of symbols and their accompanying text. A documented review step you can point to.
None of this is exotic. The failures we see come from IFU content being treated as routine documentation and routed accordingly.
Questions
Do symbols reduce the translation burden?
Should IFU translation be reviewed in-market?
What service level applies?
