Hypersensitivity reactions to ibuprofen and acetaminophen: A report of case with literature review

초록

The higher the use of nonsteroidal anti-inflammatory drugs (NSAIDs), the more reports of adverse drug reactions, especially in chil-dren than in adults. As patients with fever take several NSAIDs alternatively, suspected symptoms allergic to drugs with different chemical structures are also experienced in the clinical field. This is because it appears not only through immunological mechanisms but also through cross-intolerant reactions. Therefore, when hypersensitivity to one or more NSAIDs is present, it is important to dis-tinguish between the 2 mechanisms for future treatment planning. Although it is difficult to distinguish between the 2 mechanisms by clinical history, drug provocation test with aspirin is helpful in diagnosis. A 4-year-old patient who had urticaria/angioedema and shortness of breath after taking ibuprofen and acetaminophen visited Kangwon National University Hospital for a treatment plan using antipyretics and/or analgegics forward. We propose a diagnosis and treatment protocol for such patients with a brief literature review. (Allergy Asthma Respir Dis 2023;11:206-210)
