The best way to prevent onion allergy symptoms is to avoid onions and foods containing onions. Reading food labels and asking about ingredients in restaurants can help prevent unintentional consumption of onions.
Antihistamines can be used to relieve mild symptoms of onion allergy, such as itching and hives. In more severe cases, epinephrine may be prescribed to treat anaphylaxis.
Immunotherapy involves exposing a person to small amounts of the allergen over time to help desensitize the immune system. This can be done through allergy shots or sublingual immunotherapy (under the tongue).
