title: Tolerance to etoricoxib in children with nonsteroidal anti-inflammatory drug hypersensitivity.
abstract: BACKGROUND
  Cyclooxygenase-2 (COX-2) inhibitors have been found to be safe alternatives in adults with cross-intolerant hypersensitivity to nonsteroidal anti-inflammatory drugs (NSAIDs). However they are usually not prescribed in children and there is little information about their tolerance in the pediatric age group.
  
  
  OBJECTIVE
  This study aims to evaluate the tolerance to etoricoxib in children with hypersensitivity to multiple antipyretics.
  
  
  METHODS
  A retrospective case series of children diagnosed with hypersensitivity reactions to NSAIDs and/or paracetamol who underwent a drug provocation test (DPT) with etoricoxib. Information on atopy, family history of allergic diseases, and medication usage was collected. Outcomes of the DPTs and tolerance to etoricoxib were also evaluated.
  
  
  RESULTS
  A total of 24 children, mean age 13.5 years, had a diagnosis of cross-intolerant hypersensitivity to NSAIDs and/or paracetamol. All except one patient successfully tolerated an oral challenge with etoricoxib. Of those who passed the DPT, the majority continued to use etoricoxib with no problems. It was found to be moderately effective in reducing fever and pain.
  
  
  CONCLUSIONS
  Etoricoxib can be used as a safe alternative in older children with hypersensitivity to multiple antipyretics.
