Poison Control

Your local poison control 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 will let you talk to experts in poisoning. They will give you further instructions.

This is a free and confidential service. 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.

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. Symptoms will be treated as appropriate. The person may receive:

• Activated charcoal
• Blood and urine tests
• Breathing support, including oxygen, tube through the mouth (intubation), and breathing machine (ventilator)
• Chest x-ray
• CT (computerized axial tomography) scan
• ECG (electrocardiogram), or heart tracing
• Fluids through a vein (intravenous or IV)
• Laxative
• Medicines to treat symptoms, including flumazenil, an antidote to reverse the effect of the poison

Outlook (Prognosis)

Recovery usually occurs with proper treatment. People who are in a prolonged coma or who have respiratory complications may have permanent disability.
