Names
ibuprofen / ibuprofen

Drug class

Active ingredient: ibuprofen

  • Propionic acid derivativesATC code: M01AESource: ATC

Allergy cross-reactivity

  • Strong COX-1 inhibitors (cross-intolerance group)

    Risk level: High

    Basis: NSAID cross-reactivity is pharmacological not immunological: strong COX-1 inhibition triggers NERD/NECD/NIUA. A patient reacting to one strong COX-1 inhibitor is likely to react to others regardless of chemical class.

    Other active ingredients in the same group:

    • aspirin
    • dexketoprofen
    • diclofenac
    • etodolac
    • indomethacin
    • ketoprofen
    • meloxicam
    • naproxen
    • piroxicam

    Notes: Caution: meloxicam is preferential (not fully selective) COX-2; lower but NOT absent cross-reactivity (~6.7%, effectively moderate); kept here for safety. Confirm tolerance with a specialist.

Cross-reactivity risk is not definitive; consult an allergy/infectious disease specialist.
