Fixed Drug Eruptions With Flavoured Liquid Formulations of Over-the-Counter Analgesics: A Case Report
1Allergy and Immunology, King Abdulaziz University, Jeddah, SAU.
Abstract:
Type 4 hypersensitivity reactions convey a number of conditions that include fixed drug eruptions (FDEs). They share similar pathophysiologic backgrounds and sometimes presentation but can have very variable prognostications. Drugs are amongst the possible causes with acetaminophen and other NSAIDs being reported very frequently. We present a case of a patient reacting to flavoured oral ibuprofen and acetaminophen formulations, exhibiting FDEs with bullae formation. We describe our successful challenge to non-flavoured acetaminophen and ibuprofen. We briefly discuss FDEs in regard to their incidence, pathophysiology, and management.
