FDA DailyMed opioid boxed warning said "addition" instead of "addiction"

The opioid boxed warning on a prescription opioid listed on FDA DailyMed told prescribers to keep watching patients for addition, when the word it needed was addiction. ContextRx human-verified the miss on a live label.

Start with where it sits. The boxed warning is the black-bordered block at the top of prescribing information, the part a prescriber is most likely to read even when they read nothing else. On a prescription opioid, the box is there for a short list of named harms, and addiction is first on that list. The box's own heading says so.

Under that heading, the instructions run in a familiar order. Weigh each patient's risk before you prescribe. Keep the course short. Keep checking in with every patient over time to see whether addiction or abuse is starting to take hold.

A reviewer moving through that paragraph has seen some version of it many times. The rhythm is right. The clauses are where they should be. Every word is spelled correctly, and nothing on the screen is underlined in red. The monitoring sentence parses, so the eye slides past it.

Then one noun turns out to be the wrong one.

Published: addition

Required: addiction

That is a contextual word error: a real, correctly spelled word standing in the slot where a different word belongs. "Addition" is arithmetic, or something added on. "Addiction" is the harm the whole box exists to name. One missing letter, and the line that asks prescribers to keep checking on their patients no longer says what they are checking for.

Spellcheck clears it because both words are in the dictionary and both fit the grammar. Asking a prescriber to watch for addition reads oddly, but it is not ungrammatical, and spelling tools do not weigh meaning. Anyone reviewing prescriber-facing text, whether a medical writer, a regulatory affairs (RA) lead, or a quality control (QC) reviewer, has a simpler test for the opioid boxed warning: read the noun against the heading above it. The box title names addiction. The sentence that puts that title into practice should name it too. When the two disagree, the sentence is wrong.

There is a second lesson here. Wording copied from a reference label or template brings its mistakes along with it. Upstream text is not automatically clean, so it still needs a read after the tool has run, especially in the box, where a single noun carries the whole warning. Fix it once at the source and the correction travels the same path the error did.
