Contradictions
High
AI Statement
Many Xiidra labels specify discarding the bottle after a certain period (commonly 28 days after first opening).
Label Reference
17 (Handling/Administration instructions for single-use container: use immediately after opening; discard the single-use container, including remaining contents, immediately after administration).
Important Omissions
The on-label instructions provided in the excerpt specify that the solution from one single-use container is to be used immediately after opening and that the single-use container (including any remaining contents) should be discarded immediately after administration; the claims largely reference 'bottle' and after-opening windows instead of this immediate use/discard rule.
Importance:
High
Safety Assessment
Potential Patient Risk:
Moderate
Claims incorrectly describing after-opening discard timing (e.g., 28 days) conflict with label instructions for immediate use and discard of single-use containers, which could plausibly lead to improper product usage.

Primary Issue
Unsupported statements about expiration-date printing and guidance to replace bottles, plus a contradicted claim about a 28-day after-first-opening discard period.
Suggested Improvement
Rephrase to match provided label excerpt: use the solution from one single-use container immediately after opening and discard the single-use container (including remaining contents) immediately after administration; avoid references to a 'bottle' and specific after-opening windows unless explicitly supported in the provided label text.
