Is it true that naproxen sodium may cause a severe allergic reaction in people who are allergic to aspirin?
Yes. Naproxen sodium is a nonsteroidal anti-inflammatory drug (NSAID) that shares cross-reactivity with aspirin due to similar mechanisms like COX-1 inhibition, meaning individuals with aspirin allergies are at risk for hypersensitivity reactions to naproxen.

Evidence for · 5
Demonstrates that patients with aspirin/NSAID hypersensitivity frequently exhibit cross-reactivity to alternative analgesics due to shared mechanisms.

Explains that cross-reactivity among nonsteroidal anti-inflammatory drugs is mediated by COX-1 inhibition and arachidonic acid dysregulation, causing cross-intolerance in aspirin-sensitive patients.
