A rare case of anaphylaxis caused by mint-containing toothpaste in a child: A case report.

Anaphylaxis is a severe, potentially life-threatening systemic hypersensitivity reaction that can be triggered by food, drugs, or venom. Anaphylaxis to toothpaste, a generally well-tolerated household product, is rare. In this report, we describe a rare case of anaphylaxis in a child triggered by mint-containing toothpaste. The case involves a 9-year-old boy with a history of allergic rhinoconjunctivitis, who initially experienced localized lip pruritus from toothpaste, which progressed to systemic anaphylaxis secondary to mint allergy. Mint allergy is rarely reported, with most documented cases involving type IV hypersensitivity reactions, resulting in cheilitis. This case highlights the need for clinicians to be aware that allergic reactions, including anaphylaxis, to toothpaste are possible. A thorough review of all product ingredients is essential to ensure accurate diagnosis and appropriate management.
