Primary Issue
Claims pertain to patent status and third-party patent-tracking information, which are not included in the FDA-approved prescribing information.
Suggested Improvement
Limit content to label-based information (indication, dosing, contraindications, warnings, adverse reactions, etc.) and avoid patent/regulatory-status claims unless clearly framed as general regulatory context outside the label.
