ContextRx case index: contextual word errors on FDA DailyMed labels
Each row below is a correctly spelled wrong word ContextRx found and human-verified on a live FDA DailyMed label. Rows give the published word, the word the line needed, where on the label it sat, and the company class, never the company.
Every one of these is a contextual word error: a real word, spelled right, in a sentence that reads as normal English and means something else. That is why spellcheck passed all of them.

How to read the table
- Published word → required word is the swap, quoted as single words only.
- Label section tells you where on the label the line sat. Most are on the Drug Facts label, where lines are short and one word carries the instruction.
- Company class describes the kind of labeler, not the labeler. We never name companies, products or label IDs.
- Risk category says in plain words what the wrong word breaks.
Why spellcheck passes all of these
Every word in every row is in the dictionary. The error is in meaning, not spelling, which puts it in the spellcheck blind spot. Catching it takes a person, or a check, that reads the line for what it is supposed to do.
FAQ
What is a contextual word error on a drug label?
A real word, spelled correctly, that is wrong for its sentence, so the label reads normally but says the wrong thing.
Are these cases from real labels?
Yes. Each one was found on a live FDA DailyMed label and confirmed by a person before it was published.
Why don't the cases name the company?
The point is the failure class, not blame. Cases name the company class only.
Why did spellcheck miss these errors?
Every word is spelled correctly, so spellcheck has nothing to flag. The error is in meaning.
