Anaphylaxis is a potentially life threatening, type I hypersensitivity reaction which can occur within seconds to minutes after exposure to an allergen. Sulfites have been implicated in causing such reactions with symptoms ranging from mild to potentially life threatening. Here we present a patient who had an anaphylactic reaction secondary to exposure to sulfites found in sparkling water.
Keywords: Anaphylactic reaction; Sulfite hypersensitivity; Type I hypersensitivity.
