Consumer health products
Consumers may increase purchases of hydrocortisone cream and menthol-based products as alternatives to scratching, potentially shifting spending from other OTC remedies. Impact is marginal given the low cost and ubiquity of these products.
Minimal policy implications. Potential for increased public health messaging about dermatological care, but unlikely to trigger regulatory changes. May inform consumer education campaigns by health agencies.
