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:

  • Cleaning of exposed skin
  • Washing and examination of eyes as needed
  • Treatment of allergic reactions as needed

If the poison was swallowed, treatment may include:

  • Activated charcoal
  • Blood and urine tests
  • Breathing support, including oxygen and a tube through the mouth into the lungs (extreme cases)
  • Chest x-ray
  • CT scan (advanced imaging) of the brain
  • EKG (electrocardiogram, or heart tracing)
  • Intravenous fluids (through a vein)
  • Laxative
  • Medicines to treat symptoms
  • Tube through the mouth into the stomach to empty the stomach (gastric lavage)

 

Outlook (Prognosis)

 

Most symptoms are seen in people who are allergic to pyrethrins. Piperonyl butoxide is not very toxic, but extreme exposures may result in more severe symptoms.
