Before Calling Emergency

Get the following information, if possible:

  • Person's age, weight, and condition

  • Time it was swallowed
  • Amount swallowed

Take the container with you to the emergency room.

Poison Control

Your local poison center can be reached directly by calling the toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. This hotline number 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.

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
  • Blood pressure

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

  • Blood tests
  • Breathing support -- including oxygen, endotracheal intubation (tube through the nose or mouth into the trachea) and ventilator (breathing machine)
  • Bronchoscopy -- a camera moves down the throat to see burns in the airways and lungs
  • Endoscopy -- a camera moves down the throat to see burns in the esophagus and the stomach
  • EKG (electrocardiogram or heart tracing)
  • Eye irrigation
  • Fluids through a vein (IV)
  • Medicines to treat symptoms
  • Surgery to repair any tissue damage
  • Surgical removal of burned skin (skin debridement)
  • Washing of the skin (irrigation), perhaps every few hours for several days

Outlook (Prognosis)

How well a person does depends on how fast the poison is diluted and neutralized. Extensive damage to the mouth, throat, eyes, lungs, esophagus, nose, and stomach is possible. The ultimate outcome depends on how much damage there is.

Damage continues to occur to the esophagus and stomach for several weeks after the poison is swallowed. Treatment may require the removal of part of the esophagus and stomach.

If the poison enters the lungs, serious damage may occur, both immediately and long-term.

Swallowing the poison may cause death. It may occur as long as a month after the poisoning.
