The 25% rule keeps being reinstatedResolved

The 25%-of-remaining-expiry provision has been added back to §Nonsterile preparations twice by different editors, each citing a reference book. Both books predate the 2023 revision, which removed the provision. Would it help to keep it in the article explicitly as superseded, rather than removing it and having it return? — FiveOhThreeA (talk) 09:38, 19 November 2024 (UTC)

Yes — that is the right approach for any widely known rule that has been withdrawn. Silence invites reinstatement; a sentence saying it was removed in 2023 and remains in circulation stops it. I have written it that way and added the worked contrast so a reader can see the two approaches give different answers. — Compounding_Cate (talk) 12:15, 19 November 2024 (UTC)

The worked contrast is the useful part. It also demonstrates why revision status matters generally, which is a lesson worth more than the specific rule. — CitationChaser (talk) 08:52, 20 November 2024 (UTC)

No reinstatements since. Marking resolved, with the note that this pattern — a withdrawn rule surviving in secondary sources — is worth watching for elsewhere. ✓ DoneFiveOhThreeA (talk) 10:07, 22 November 2024 (UTC)

Resolved. This thread is closed. Reopening it is fine if new sources appear; please add a new subsection rather than editing the closed discussion.
