What Are Your Shellfish Allergy Treatment Options?

Food Allergy Testing

Food allergy testing is a useful way to determine which shellfish cause a reaction. Some people are sensitive to a wide variety of shellfish, while others might be allergic only to a specific species. An oral challenge test is one food allergy testing approach used by Dr. Chacko from our clinics in Atlanta, Canton and beyond.


Avoidance is the safest way to prevent an allergic reaction. Staying cautious and checking the ingredients list of food items can prevent unexpected reactions. However, you simply cannot always be assured that a food item purchased from a store or restaurant stays true to the ingredients list or published recipe.


To reduce the impact of a mild reaction you may be prescribed antihistamines or other medications. For severe reactions, an epinephrine auto-injector can be used to prevent anaphylaxis.

Oral Immunotherapy

Oral immunotherapy is a desensitization process that involves building tolerance to an allergen. Allergy sufferers gradually consume small amounts of the problem food until their immune system stops overreacting to its presence. Oral immunotherapy is not commonly used for shellfish allergies. A consultation with Dr. Chacko can determine the right approach to take.

If you notice some of the following symptoms after consuming shellfish, you are likely experiencing an allergic reaction.

  • Stomach pains and nausea
  • Dizzy or lightheaded feeling
  • Skin redness or hives
  • Shortness of breath or wheezing
  • Swollen lips or tongue
