[206] Aspirin can exacerbate symptoms among those with chronic hives, or create acute symptoms of hives.

It does so by acetylating the hydroxyl of a serine residue at the 530 amino acid position. [6] Normally COX produces prostaglandins, most of which are pro-inflammatory, and thromboxanes, which promote clotting.
