Summary
The majority of claims are absent from the provided FDA label excerpts (which appear to be for XIFYRM/IV meloxicam, not Mobic or ibuprofen). Only limited meloxicam-specific support is present (COX mechanism and ~21-hour half-life), while most comparative claims vs ibuprofen and numerous product-availability/patent/cost assertions are unsupported by the supplied label content.
Category Scores
Accurate Statements
Meloxicam has a half-life of about 20 hours.
Supported in part: label states mean elimination half-life approximately 21 hours (12.3 Pharmacokinetics).
Meloxicam (as an NSAID) works via inhibition of cyclooxygenase (COX-1 and COX-2).
Supported: mechanism involves inhibition of COX-1 and COX-2 (12.1 Mechanism of Action).
Renal risk is increased in dehydrated/hypovolemic patients and elderly patients.
Supported in part: label describes highest risk for renal toxicity includes dehydration/hypovolemia and the elderly (5.6; 8.5 Geriatric Use).
Unsupported Statements
Meloxicam and ibuprofen are NSAIDs that relieve arthritis pain and inflammation by blocking COX enzymes.
The provided label excerpt does not mention ibuprofen, 'arthritis,' or COX-enzymatic blocking as a label-supported mechanism for ibuprofen specifically (12.1 supports meloxicam; absence of ibuprofen/arthritis comparison).

Meloxicam peak effect occurs in 4 to 5 hours.
Label provided does not support that phrasing; XIFYRM Tmax in Table 4 is ~0.045 hours (12.3).
Ibuprofen peak effect occurs in 1 to 2 hours.
No ibuprofen peak effect timing is included in supplied label excerpts.

Contradictions
Important Omissions
Boxed warning and explicit boxed-warning-related claims (e.g., pregnancy/labor/pediatric) could not be audited from the provided label excerpts because the supplied sections do not include the boxed warning text.
Importance:
Moderate
Safety Assessment
Potential Patient Risk:
High
The response contains many unsupported comparative efficacy/safety and pharmacokinetic/onset/ulcer-rate/dosing/availability claims vs ibuprofen that are not supported by the supplied FDA label excerpts (which focus on XIFYRM IV meloxicam for postoperative pain). Unsupported medication comparison and dosing/timing assertions could mislead clinical interpretation even if the meloxicam-specific half-life/mechanism claims are partially supported.

Primary Issue
Most claims are absent from the provided FDA label excerpts and many are comparative vs ibuprofen (not covered in the provided label). Additional non-label assertions (brand/generic/patent status/OTC availability/cost/study citations) are unsupported by the label content provided.
Suggested Improvement
Restrict assertions to what is explicitly present in the supplied label excerpts for XIFYRM (e.g., meloxicam COX mechanism; XIFYRM dosing schedule; meloxicam half-life; label-supported NSAID risks and specific interaction/monitoring statements) and remove ibuprofen comparisons, arthritis/OA/RA comparative claims, dosing/half-life/onset/peak timing for ibuprofen, and non-label external-study/patent/cost/OTC availability statements.
