Association Between Nasal Provocation Test With Lysine-Acetylsalicylate(ASA) and Clinical Diagnosis in Patients With Aspirin/Nonsteroidal Anti-Inflammatory Drugs(NSAIDs) and/or Acetaminophen Immediate Sensitivity Reactions

This study aims to compare the efficacy of nasal provocation test with Lysine-Acetylsalicylate in patients with history of NSAIDs hypersensitivity between mucocutaneous symptoms and respiratory symptoms and laboratory outcomes.

Inclusion Criteria:

Exclusion Criteria:

• Patients who cannot discontinue drugs before the test as follow

  • Nasal corticosteroids/Oral corticosteroids/Leukotriene modifiers for 1 week
  • Short-acting antihistamines for 3 days
