The only effective treatment for a food allergy is the complete removal of food allergens from the diet. The diligent practice of avoidance is a necessity for anyone suffering from a food allergy.

Every single allergic reaction to seafood has the potential to cause anaphylaxis. For this reason, a person should immediately use an injection of epinephrine if they suspect they are having an allergic reaction. Epinephrine is a synthetic form of adrenaline that, when injected, is a powerful bronchodilator, opening breathing tubes and restoring normal respiration quickly. After using epinephrine, an individual should immediately call for medical assistance.

If an allergic reaction to a food has proved to be only minor (based on a physician's evaluation), there are some alternatives for the relief of the less serious allergy symptoms These medications can help relieve symptoms somewhat, but are by no means a cure for the condition. Only avoidance of problem foods can successfully treat a food allergy.

Though some allergy medications are available over-the-counter, they should be used only under the direction of a physician. Medications that may be recommended include:

• Antihistamines. Medications that provide relief for more basic allergy reactions such as hives, sneezing, runny nose and gastrointestinal symptoms. Antihistamines directly counteract the effects of histamines, which are chemicals responsible for most seafood allergy symptoms. With mild symptoms, these drugs are usually administered orally. For more severe allergic reactions, a physician may recommend an injected form of the drug.
  

  

• Bronchodilators. Medications that open the airways of the lung, relieving symptoms such as shortness of breath or wheezing. They may be recommended for people whose seafood allergies trigger asthma attacks or asthma-like symptoms. They are usually breathed directly into the lungs using an inhaler.
  
  
• Corticosteroids. Medications that reduce inflammation. These drugs are often taken regularly to prevent an allergic attack or reduce the severity of symptoms.
