Recommendation
Partially Aligned
Primary Issue
Non-label claims about pricing/discount cards and patient assistance are not supported by the provided FDA labeling; major boxed warning/contraindication/safety information is omitted.
Suggested Improvement
Limit medical claims to the specific FDA-labeled indications and explicitly tie them to the labeled product (promethazine HCl suppositories). Include the boxed warning and contraindications (especially pediatric <2 years respiratory depression) and key administration constraints (rectal only; not recommended for <2 years). Remove or clearly separate non-label financial/discount-card assertions from label-based content.
