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 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.
What to Expect at the Emergency Room
Take the container with you to the hospital, if possible.
The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated. The person may receive:
- Activated charcoal
- Blood and urine tests
- Breathing support, including oxygen, a tube through the mouth into the throat, and a breathing machine
- Chest x-ray
- CT scan (advanced brain imaging)
- EKG (electrocardiogram, or heart tracing)
- Intravenous (IV) fluids through a vein
- Medicines to reverse the effects of the drug and treat symptoms
- Tube through the mouth into the stomach to empty the stomach (gastric lavage)
With proper care, full recovery is likely. But people with aplastic anemia (suppression of red blood cell production by the bone marrow) or those who overdose on many different substances may not recover fully.
