People suffer from different kinds of allergies. Iodine allergy is a rarely known allergy, but one that some people will have. It is not known considering that iodine has never been considered to be an allergen. Some people are however hypersensitive to the iodine and therefore considered to have the allergy. This is an element that is found in different places, including the human body. The reactions or allergies are therefore very rare. The rare hypersensitive cases, however cannot be ignored since in a few cases the allergy has led to patient deaths.
Patients who are hypersensitive to iodine exposure may experience rash also known as contact dermatitis. Hives can also be experienced when iodine is ingested. Anaphylactic is a rare symptom of the allergy, but it is a condition that will require proper medical attention. This condition will come with symptoms which include diarrhea, confusion, abdominal pain, rapid pulse, nausea or vomiting, lightheadedness, heart palpitations, breathing difficulties and hives.
Weak iodine solution in tincture form commonly used for disinfecting around medical settings can easily lead to rashes in people who are hypersensitive to iodine.
Povidone iodine allergy
This is an allergy which results from topical antiseptics that contain povidine iodine. The povidine is a polyvinylpyrrolidone and iodine solution. In very rare cases, this solution can lead to contact dermatitis that is similar to a chemical burn. The positive allergic reactions are however not always as a result of iodine by the povidine copolymers which are iodinated. Povidine alone has actually resulted in anaphylactic shock among patients, but in very rare cases.
Iodine contrast allergy
Iodine is radio opaque since it is a heavy element. It is therefore used as a radiocontrast agent in X-rays, especially for intravenous injections. Contrast dyes that contain iodine have also led to anaphylactic reactions in hypersensitive patients, although in very small numbers.
How the allergy test is done
An iodine allergy test will usually be done when a hypersensitive case is suspected. A patch test in this case works best. Iodine will be applied to the patch and then placed into the skin of the patient. The care providers will then wait to check the reaction that follows the contact to make a diagnosis.
Treating Iodine allergy
In cases where the iodine allergy has been diagnosed, a corticosteroid cream could be prescribed. This can also be found in oral form like prednisone. The prescriptions help in relieving the symptoms of the allergy most especially the rash that is common among the hypersensitive patients. Patients with anaphylactic shock will however need immediate medical attention in shot form. Epinephrine or adrenaline shot will be administered to treat the condition.
Allergies can be in many forms and it is easy to overlook. It is however important to find out why there are certain reactions when you eat or come in touch with certain elements or foods. An allergy is easier to treat when the root cause is established. It is not advisable to ignore an allergy for long to reduce any adverse effects over a period of time.
