Sodium Metabisulfite Allergy

Sodium metabisulfite is a common food preservative and industrial chemical that can cause allergic reactions in some individuals. Allergic reactions to sodium metabisulfite can range from mild symptoms such as hives, itching, and nausea to more severe symptoms such as difficulty breathing, swelling of the face, and anaphylaxis (a life-threatening allergic reaction).

Sodium metabisulfite allergy is diagnosed through skin prick testing or blood testing for specific IgE antibodies. Avoiding exposure to sodium metabisulfite is the primary treatment for those with an allergy to this compound.

Sodium metabisulfite is found in many foods and beverages, including wine, beer, dried fruits, and processed meats. It is also used in the production of certain medications, photographic materials, and personal care products. Because of its widespread use, it is important for individuals with a known allergy to sodium metabisulfite to read ingredient labels carefully and avoid products that contain this compound.
