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 to the hospital with you, if possible.

The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure.

Tests that may be done include:

Treatment may include:

  • Fluids through a vein (by IV)
  • Laxative
  • Medicines to relieve pain

Outlook (Prognosis)

How well someone does depends on how much carbolic acid was swallowed and how quickly treatment is received. The faster medical help is given, the better the chance for recovery.

Damage continues to occur to the esophagus and stomach for several weeks after the poison was swallowed. Death may occur as long as a month later.
