Primary Issue
Key indication and administration/safety specifics are not supported by the provided label excerpts (especially Section 1 and Section 2), and several adverse-event examples are not explicitly named in the supplied text.
Suggested Improvement
Only retain claims that are directly supported by the provided label sections (e.g., Divigel contains estradiol; applied once daily to the skin; thigh application area; CYP3A4 interaction statement). Remove or re-verify statements about specific indications, application instructions (clean/dry skin; upper arm use; spreading; washing guidance), and specific adverse events (blood clots/stroke/MI/cancer types) unless the corresponding label text is included.
