Summary
The AI statements concern Lipitor shelf life after opening and expiration/packing guidance, but the provided FDA label excerpts do not include any shelf life, storage-duration after first use, post-expiration use, or opened-bottle/tablet guidance. Therefore, the claims cannot be supported by the supplied prescribing information and include multiple unsupported/generalized safety assertions.
