BACKGROUND: Ibuprofen is the most frequently used over-the-counter nonsteroidal anti-inflammatory drug (NSAID) in North America. While it has been commonly implicated in drug-induced hypersensitivity reactions, there is limited literature specifically on ibuprofen hypersensitivity.
OBJECTIVES: To characterize the demographics and clinical course of hypersensitivity reactions in a cohort of patients with ibuprofen allergy.
METHODS: A retrospective chart review of patients diagnosed with ibuprofen allergy was conducted between 2008 and 2016 in an allergy clinic at a tertiary care academic institution. Demographics and clinical information were obtained, and severity of reactions was assessed by a standardized grading system.
RESULTS: A total of 41 patients were included of whom 27 were female. The mean age at first reaction to ibuprofen was 33 ± 13.9 years. The medi an time from the first reaction to the time of diagnosis was 1 year (0-3). The median time from ibuprofen exposure to the onset of symptoms was 30 min (16-101). The median duration of symptoms was 180 min (60-1,440). Urticaria and angioedema were seen in 90% of patients. The reactions were either mild (46%) or moderate (51%) in severity, but 1 patient had severe anaphylaxis. Cross-reactivity to other NSAIDs or acetaminophen was seen and presented with mostly mild reactions.
CONCLUSION: In our cohort of patients, ibuprofen hypersensitivity affected females more commonly than males, and presented with mainly cutaneous manifestations. Onset of symptoms was rapid (< 60 min). Reactions typically ranged in severity from mild to moderate although there was a risk of severe anaphylaxis. There was potential cross-reactivity with other NSAIDs or acetaminophen. The results of our study contribute to the understanding of the demographics and clinical course of ibuprofen hypersensitivity reactions.
