Before Calling Emergency
Determine the following information:
Patient's age, weight, and condition
Name of the product (ingredients and strengths, if known)
Time it was swallowed
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 U.S. 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.
Take the container with you to the hospital, if possible.
The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. The patient may receive:
Medicines to treat symptoms
Medicines called chelators to remove mercury from the bloodstream
Methods to make the person vomit (throw up)
This substance is very poisonous. How well the patient does often depends on what symptoms occur within the first 10 to 15 minutes after swallowing it and how quickly treatment is received. Kidney failure and death can occur, even with small doses.
If the poisoning has occurred slowly over time, any brain damage may be permanent.
