Poison Control What to Expect at the Emergency Room

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 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.

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
  • Breathing support, including tube through the mouth and breathing machine (ventilator)
  • EKG (heart tracing)
  • Chest x-ray
  • Fluids through a vein (by IV)
  • Laxative
  • Medication to reverse the effects of the medication

Prognosis (Outlook)

How well the person does depends on the amount of the substance swallowed and how quickly treatment is received. The faster the person gets medical help, the better the chance for recovery. This type of overdose is usually mild. Taking too much of this medication is not usually a problem. 

The person may have some pain in their stomach and vomiting (possibly with blood). However, severe internal bleeding is possible, and blood transfusion may be needed. Endoscopy, or passing a tube through the mouth into the stomach, may be required to stop internal bleeding. A large overdose can cause serious damage to both children and adults, and death may occur.
