Four Cases of Drug Allergy Caused by Non-Steroidal Anti-Inflammatory Drugs in Children / 소아알레르기및호흡기학회지

ABSTRACT

Acetaminophen and non-steroidal anti-inflammatory drugs (NSAIDs), which reduce the production of prostaglandin by inhibiting cyclooxygenase (COX), are widely used in children as antipyretic, analgesic, or anti-inflammatory drugs. They are known to be a major cause of pediatric drug allergies, which are diagnosed by a drug provocation test. The mechanism comprises an immunoglobulin E- or T cell-mediated immune reaction or pseudoallergy caused by the inhibition of COX-1. The diagnosis of NSAIDs drug allergy requires a differential, because there is a high cross-reactivity between NSAIDs. In this study, oral provocation tests with ibuprofen, acetaminophen, diclofenac and celecoxib were carried out, and various types of NSAIDs and acetaminophen allergies were observed. Safe drugs were recommended for each patient according to the test results. We report four cases of NSAIDs and acetaminophen allergy and include the results of oral provocation tests.
