Iodine Poisoning is the accidental or intentional intake of the iodine containing compound. The intake may be through swallowing or inhaling vapors of such compounds.


What is Iodine Poisoning?

  • Iodine (I) is an element that exists as metallic grey solid. It is also a very important mineral nutrient required by the body in traces, which is obtained via dietary intake
  • Iodine and its compounds have various applications including as an industrial catalyst in the production of polymeric compounds, animal feed supplements, pigments, pharmaceutical products, and as a lab chemical
  • Iodine Poisoning is the accidental or intentional intake of the iodine containing compound. The intake may be through swallowing or inhaling vapors of such compounds
  • The condition is diagnosed based upon the clinical history, combination of signs and symptoms, and additional tests (that may include, in some cases, radiological studies and laboratory tests)

Iodine Poisoning is also known as Iodine Toxicity.

What are the Causes of Iodine Poisoning?

  • Iodine Poisoning is caused by the ingestion of iodine compounds or products. The compound may affect the skin or eye, resulting in related symptoms. Inhalation of iodine vapors may also result in toxicity
  • This intake could be accidental, or in some cases intentional, to bring self-harm
  • Iodine is found in chemicals used for photography, inks and coloring agents, in certain organic compounds, cloud seeding, and in radioactive isotopes used for medical tests

Note: The drug can interact with other prescribed or non-prescribed medications in the body. Such interactions may enhance the therapeutic effects of the drug or other medications being taken, resulting in undesired side effects.

What are the Signs and Symptoms of Iodine Poisoning?

The signs and symptoms of Iodine Poisoning can vary from one individual to another. It may be mild in some and severe in others. Several systems of the body may be affected.

The signs and symptoms of Iodine Poisoning may include

  • Abdominal pain; irritation of the stomach
  • Skin lesions that resemble acne
  • Mouth ulcers
  • Bluish discoloration of skin on lips and beneath fingernails
  • Breathing difficulties; coughing
  • Breathing-in iodine vapors may result in lung irritation and edema (fluid in the lungs)
  • If the eye is affected, it may result in burning and irritation of the eye. Similarly, if the skin is affected, it can result in chemical burns
