Tips for Shellfish Allergies

If you have a shellfish allergy or any food allergy, special precautions must be taken to avoid a reaction. Here are some suggestions:

1.    Read the labels carefully. Shellfish are ingredients in food such as sauces, soup, stock, Asian food, chips and dip, salad dressing and food supplements.

2.     Pay attention when eating out, many restaurants use the same oil for shrimp (shellfish), French fries and chicken.

3.    Some products sold as imitation shellfish, still can contain shellfish flavouring that can also trigger a reaction.

4.    Fish fingers, nuggets or burgers also contain shellfish parts, even if it does not state this on the package.

5.     A reaction can also come from touching the shellfish, depends of the severity of the person’s allergic reaction.


The best treatments for this allergy are to stay away from shellfish completely. If you have mild symptoms like itching or a rash, take loratadine or diphenhudramine that is in the form of antihistamines.

Applying a calamine lotion and ice, will help the discomfort of hives by reducing the blood vessels. This will help the inflammation clear up.

Taking Peppermint tea and the milk of magnesia (milky-white liquid that is made from magnesium hydroxide, purified water, and sodium hypochlorite) helps to relieve milder symptoms.

When having more severe symptoms like anaphylaxis, the doctor will usually give an injection called epinephrine (EpiPen) .
