A drug allergy is a reproducible reaction mediated through the immune system. [15] Shellfish do not manifest the proteins -parvalbumin (found in bony fishes) or -parvalbumin (found in cartilaginous fishes such as sharks and rays), so there is not cross-reactivity of shellfish allergy to fish allergy. [7][8], After the chemical mediators of the acute response subside, late-phase responses can often occur due to the migration of other white blood cells such as neutrophils, lymphocytes, eosinophils, and macrophages to the initial reaction sites. Be sure you understand how to properly and promptly use an epinephrine auto-injector. While on the other hand, if a person consumes mollusks, which include clams, mussels, oysters, scallops, squid, and octopus, it takes comparatively more time for an allergic reaction to occur. 2015;168(4):269-76. doi: 10.1159/000443736.
