Iodine poisoning

 

Iodine is a naturally occurring chemical. Small amounts are needed for good health. However, large doses can cause harm. Children are especially sensitive to the effects of iodine.

NOTE: Iodine is found in certain foods. However, there is normally not enough iodine in foods to harm the body. This article focusses on poisoning from exposure to non-food items that contain iodine.

This article is for information only. Do NOT use it to treat or manage an actual poison exposure. If you or someone you are with has an exposure, call your local emergency number (such as 911), or your local poison center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States.

  • Dyes and inks
  • Lugol's solution
  • Pima syrup
  • Potassium iodide
  • Radioactive iodine used for certain medical tests or the treatment of thyroid disease

Symptoms

 

Symptoms of iodine poisoning include:

  • Abdominal pain
  • Coughing
  • Delirium
  • Diarrhea , sometimes bloody
  • Fever
  • Gum and tooth soreness
  • Loss of appetite
  • Metallic taste in mouth
  • Mouth and throat pain and burning

  • Seizures
  • Shock
  • Shortness of breath
  • Stupor (decreased level of alertness)
  • Thirst
  • Vomiting

 

Home Care

 

Seek immediate medical help. DO NOT make a person throw up unless told to do so by Poison Control or a health care professional.

Give the person milk, or cornstarch or flour mixed with water. Continue to give milk every 15 minutes. DO NOT give these items if the person is having symptoms (such as vomiting, convulsions, or a decreased level of alertness) that make it hard to swallow.

 

Before Calling Emergency

 

The following information is helpful to emergency assistance:

  • Person's age, weight, and condition (for example, is the person awake or alert?)
  • Name of the product (ingredients and strengths, if known)
  • Time it was swallowed
  • Amount swallowed

However, DO NOT delay calling for help if this information is not immediately available.

 

Poison Control

 

Your local poison center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. This hotline number will let you talk to experts in poisoning. They will give you further instructions.

This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. You can call 24 hours a day, 7 days a week.

 

What to Expect at the Emergency Room

 

The health care provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. The person may receive:

  • Activated charcoal
  • Airway support, including oxygen, breathing tube through the mouth (intubation), and breathing machine (ventilator)
  • Blood and urine tests
  • Chest x-ray
  • EKG (electrocardiogram, or heart tracing)
  • Fluids through a vein (intravenous or IV)
  • Laxative
  • Medicines to treat symptoms

 

Outlook (Prognosis)

 

How well a person does depends on the amount of poison swallowed and how quickly treatment was received. The faster a person gets medical help, the better the chance for recovery.

Esophageal stricture (narrowing of the esophagus, the tube that carries food from the mouth to the stomach) is a possible complication. Long-term effects of iodine overdose include thyroid gland problems.
