What the FDA labels say
From the Sulindac label · effective 2026-05-08
Sulindac should not be given to patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs.
This symptom complex typically occurs in asthmatic patients who experience rhinitis with or without nasal polyps, or who exhibit severe, potentially fatal bronchospasm after taking aspirin or other NSAIDs (see CONTRAINDICATIONS and PRECAUTIONS – Preexisting Asthma ).
As with other non-steroidal anti-inflammatory drugs, borderline elevations of one or more liver tests without any other signs and symptoms may occur in up to 15% of patients taking NSAIDs including sulindac.
Anaphylactic/Anaphylactoid Reactions As with other NSAIDs, anaphylactic/anaphylactoid reactions may occur in patients without known prior exposure to sulindac.
From the Flurbiprofen label · effective 2026-02-03
Flurbiprofen tablets are contraindicated in the following patients: Known hypersensitivity (e.g., anaphylactic reactions and serious skin reactions) to flurbiprofen or any components of the drug product [ see Warnings and Precautions (5.7 , 5.9) ] History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs.
History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs ( 5.7 , 5.8 )
Avoid administration of more than one NSAID at a time.
Exacerbation of Asthma Related to Aspirin Sensitivity A subpopulation of patients with asthma may have aspirin-sensitive asthma which may include chronic rhinosinusitis complicated by nasal polyps; severe, potentially fatal bronchospasm; and/or intolerance to aspirin and other NSAIDs.
Because cross-reactivity between aspirin and other NSAIDs has been reported in such aspirin-sensitive patients, flurbiprofen is contraindicated in patients with this form of aspirin sensitivity [ see Contraindications (4) ].
