Recommendation

Primary Issue
The response (and its claims list) relies on shelf life/expiration, storage, opened-use, packaging, disposal, and FDA/legal-risk assertions that are not contained in the provided FDA label text excerpt. Only adverse reaction cross-reference structure is addressed.
Suggested Improvement
Limit claims strictly to the provided label excerpt, or provide the relevant label sections (e.g., HOW SUPPLIED/STORAGE AND HANDLING) and quote/align statements directly to those sections before asserting shelf life, expiration placement, opened-use duration, storage parameters, or disposal instructions.
