Side effects and contraindications
Taking the tablets on an empty stomach may lead to an irritation of the stomach lining.
In rare cases, the intake of iodine tablets may trigger allergic reactions, such as: skin rash, itching and burning eyes, a cold, dry cough, diarrhoea, headache, high temperature or similar symptoms.
In individual cases the intake of iodine tablets may cause an iodine-related thyroid-hyperfunction. Symptoms can include an accelerated pulse, sweating, insomnia, shakiness, diarrhoea or weight loss. Please contact your General Practitioner (GP) should you notice any of these symptoms.
Persons who suffer or suffered from thyroid-hyperfunction should only take iodine tablets after having consulted their attending doctor.
