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 is for information only and not for use in the treatment or management of an actual poison exposure. If you have an exposure, you should call your local emergency number (such as 911) or the National Poison Control Center at 1-800-222-1222.
Radioactive iodine used for certain medical tests or the treatment of thyroid disease
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 patient is having symptoms (such as vomiting, convulsions, or a decreased level of alertness) that make it hard to swallow.
Before Calling Emergency
If possible, determine the following information:
Patient'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
However, DO NOT delay calling for help if this information is not immediately available.
Poison Control, or a local emergency number
The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national 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. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.
