How is Sulfite Allergy Treated?

Generally, avoidance of foods and medications containing sulfites should be avoided in people with known or suspected sulfite allergy. This should be successful given the mandate by the FDA to label foods containing less than 10 ppm of sulfites. It is important to note that the terms sulfur dioxide, sodium or potassium bisulfite, sodium or potassium metabisulfite, and sodium sulfite are other names for sulfites.

The FDA ban on sulfites from fresh fruits and vegetables (such as in salad bars) in restaurants has significantly reduced the risk of accidental ingestion of sulfites. However, unlabeled sulfite-containing foods remain in restaurants, with sulfites in potatoes being the major concern. Therefore, sulfite allergic people should avoid all potato products in restaurants except for baked potatoes with skins intact.

Severe allergic reactions and anaphylaxis may require treatment with injectable epinephrine, asthma symptoms may require the use of inhaled bronchodilator solutions (those that do not contain sulfites). It would be prudent for people with severe sulfite allergy to carry injectable epinephrine (Epi-Pen or Twinject) and to obtain a Medic-Alert bracelet.
