Primary Issue
Multiple extracted statements are absent from the provided Pepcid label excerpts (manufacturer/other drug/patent/biosimilar/market claims) and safety-critical label content (contraindications, warnings/precautions, adverse reactions, dosing, specific populations) is omitted.
Suggested Improvement
Restrict statements to on-label content present in the provided label sections (e.g., GERD indications and any provided dosing/interaction/safety text). Do not include unrelated drugs or patent/biosimilar/market assertions unless supported by the supplied label text.
