Individuals who suspect that they are allergic to rice should consult an allergist/immunologist. In order to diagnose the cause of the patient’s symptoms, the physician will collect the patient’s medical history, perform a physical examination and employ allergy tests (e.g., skin tests, blood tests).

Once the diagnosis of rice allergy has been confirmed, the patient will be advised to avoid the grain. Those with a rice allergy must completely avoid rice because consumption can cause anaphylactic shock, a potentially life-threatening reaction. There is no way to predict whether a person will have a mild or severe reaction after consuming a food they are allergic to. People with rice allergies must carefully read the ingredient labels on food products and be cautious when eating at restaurants.

Those who avoid rice are unlikely to miss any essential nutrients. However, good rice substitutes can be found in the following:

• Sorghum
• Millet
• Quinoa
• Cornmeal
• Buckwheat

Wild rice can serve as a substitute for some who are allergic to rice. However, in others, it is likely to trigger a cross reaction. People with food allergies should consult a qualified physician before consuming an "alternate" food.

People with rice allergies will also be given instructions in case of accidental consumption. Individuals with a history of mild reactions may be instructed to take antihistamines. Those with a history of severe reactions may be prescribed an allergy kit.
