Recommendation
Not Aligned
Primary Issue
Majority of claims are absent/unverifiable in the provided label excerpts, including regimen/dosing format and multiple safety/monitoring assertions.
Suggested Improvement
Restrict claims to those explicitly supported by provided label excerpts (e.g., indication) and, for safety/drug-interaction statements, cite the specific warning/precaution or drug interaction sections. Remove country-specific availability/pricing/practice and unsupported 'common' patient behavior assertions unless the label provides them.
