I recognize an iodine allergy by these symptoms
On first contact with iodine, an iodine allergy does not yet cause any symptoms. Only at the second contact is the immune system already sensitized to iodine and triggers various symptoms within 12 to 48 hours after contact with iodine. For this reason, the iodine allergy is also classified as a type 4 reaction, as the symptoms appear with a delay.
In the foreground is the development of eczema. Eczema is a certain type of skin rash that presents itself with redness and the formation of blisters. Furthermore, the rash can also weep and cause itching.
In some cases, the rash changes in the course of time, resulting in crusts or scales. The rash affects especially the areas around the head, such as the skin behind the ears and the area around the eyes. Skin reactions on the trunk, arms and legs can also be observed.
In addition to the reactions on the skin, an iodine allergy with all kinds of unspecific symptoms, such as coughing, malaise and headaches, can become noticeable. A reaction of the respiratory tract is also possible with an iodine allergy. This causes the airways to constrict and a feeling of breathlessness develops. In extreme cases the iodine allergy can also trigger an anaphylactic shock. It is the result of the maximum overreaction of the immune system and is a serious condition which must be treated in hospital.
Treatment of an iodine allergy
The therapy depends on the severity of the allergic reaction. If the skin symptoms are the only symptoms, they can be treated with antihistamines or a cream containing cortisone from the pharmacy. For further care of the skin areas it is recommended to treat them with greasy cream ointments.
In the case of stronger reactions involving the respiratory tract, treatment with the stress hormone epinephrine may be necessary to re-expand the airways.In the event of such a reaction, the patient should be well monitored to detect further circulatory problems at an early stage and take appropriate action. If the allergic reaction occurs after an examination with contrast medium, the patient should definitely be treated in hospital by emergency physicians. The risk of the patient suffering anaphylactic shock should not be neglected. It is important to constantly measure vital parameters such as blood pressure and pulse and to treat them quickly with acute medical care if they deteriorate.
