Contradictions

Recommendation

Primary Issue
Multiple claims are not supported by the provided prescribing information excerpts (trade names/marketing, USP/manufacturer labeling, and “fluid retention” use).
Suggested Improvement
Restrict statements to elements explicitly supported by the provided label excerpts (e.g., diuretic mechanism; hypertension indication). Remove or qualify claims about generic/trade names and any unlisted indications unless supported by the provided label text.
