RESUMEN
Tipepidine hibenzate (Asverin) is commonly used as an antitussive drug for acute and chronic cough in various age groups and is generally safe and well-tolerated. However, we experienced a case of tipepidine hibenzate-induced anaphylactic shock in a 1-year-old boy. After ingesting cold medication including tipepidine hibenzate, the patient presented with generalized erythema and urticaria, swollen face, coughing, wheezing and vomiting, together with hypotension and a decreased level of consciousness. To identify the culprit drug, we performed skin prick tests (SPTs) and oral drug provocation tests (DPTs). SPTs revealed a negative reaction for all drugs, but DPTs caused a positive reaction only for a full therapeutic dose of tipepidine hibenzate. Physicians need to consider tipepidine hibezate as a culprit drug when anaphylaxis occurs after taking anticough or common cold medication.
