A fish oil allergy and an iodine allergy are two different conditions and are not related to one another. According to the Food Allergy and Anaphylaxis Network, nearly 7 million Americans suffer from a seafood allergy. While most fish oil supplements do not contain complete fish proteins, they are still not recommended to people with a fish allergy. Talk with your doctor if you suspect that you are allergic to fish oil or iodine.
Fish Allergy
A fish oil allergy is the same allergic reaction that occurs from fish proteins. A seafood allergy is considered one of the most common food allergies, according to Allergic Child. If you have a fish oil allergy, your immune system overreacts to the proteins found in most seafood. The body mistakes the proteins as harmful substances and begins attacking the proteins with IgE antibodies. These antibodies trigger certain cells in the body to produce histamine, a chemical that helps to defend the body. Too much histamine leads to common allergy symptoms.
Iodine
Iodine is use medically for various reasons. Some of the most common uses are as an expectorant, an antiseptic and a thyroid agent. Drugs.com warns that iodine is a highly corrosive toxin that needs to be used under a doctor's supervision. An iodine allergy is considered uncommon, but can occur in anyone.
Allergy Symptoms
Both a fish oil allergy and an iodine allergy will manifest the same symptoms. These primarily include cardiovascular, respiratory and digestive reactions. You may feel faint or lightheaded as a result of an allergic reaction. Common respiratory symptoms include shortness of breath, nasal congestion, sinus pain, wheezing, chest pain and coughing. After digesting fish oil or iodine, you may experience abdominal cramping, gas, vomiting or diarrhea.
Treatment
Mild allergic reactions to fish oil or iodine may be treated with antihistamines. These drugs block the body's ability to produce histamine, resulting in a reduction of allergy symptoms. Gastrointestinal medications will not help to alleviate stomach issues from an allergic reaction. Drink plenty of water and allow your body to rid itself of the allergen. If you experience anaphylactic shock, you may need an injection of epinephrine to prevent further serious complications.
Warning
Anaphylactic shock is considered common among people with a fish oil allergy. Proper testing should be performed to determine how allergic you are to fish oil. If you have a severe allergy, wear a medical ID bracelet and inform close friends, family and co-workers of your condition.
