Poison Control
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 emergency room.
See Poison Control center.
What to Expect at the Emergency Room
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 cause vomiting
- Blood tests to check iron levels
- A nasogastric (NG) tube thru the nose into the stomach to empty the stomach (gastric lavage)
- X-ray to make sure all iron tables are gone from the stomach
- Medicines to treat symptoms
Outlook (Prognosis)
If the patient has no symptoms after 48 hours of swallowing the iron, there is a good chance of recovery. However, some people have died up to a week after an iron overdose. The more quickly a patient receives treatment, the better the chance for survival.
