Recommendation
Not Aligned
Primary Issue
Unsupported adverse-reaction incidence/percentage claims and unsupported serious safety associations; missing key label-aligned safety sections.
Suggested Improvement
Remove or correct all adverse-event frequency/percent claims and serious warning associations unless directly supported by the exact FDA label adverse-reactions and warnings-precautions text for the specific product/indication. Add label-aligned content for contraindications, dosing/administration safety, boxed/major warnings (if applicable), and relevant population-specific statements with exact section citations.
