Home Care

Get medical help right away. DO NOT make a person throw up unless told to do so by poison control or a health care provider.

If the chemical is on the skin or in the eyes, flush with lots of water for at least 15 minutes.

If the person swallowed the metal cleaner, give them water or milk right away, unless a provider tells you not to. DO NOT give anything to drink if the person has symptoms that make it hard to swallow. These include vomiting, convulsions, or a decreased level of alertness.

If the person breathed in the poison, move them to fresh air right away.

Before Calling Emergency

Have this information ready:

  • Person's age, weight, and condition
  • Name of the product (ingredients, if known)
  • Time it was swallowed
  • Amount swallowed

Poison Control

Your local poison 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 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.

What to Exect 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:

  • Breathing support, including a tube through the mouth into the lungs, and a breathing machine (ventilator).
  • Bronchoscopy. Camera placed down the throat to see burns in the airways and lungs.
  • Chest x-ray
  • EKG (heart tracing)
  • Endoscopy. The placement of a camera down the throat to see the extent of burns to the esophagus and the stomach.
  • Fluids through a vein (IV)
  • Surgery to remove burned skin
  • Tube through the mouth into the stomach to wash out the stomach (gastric lavage).
  • Washing of the skin (irrigation). Perhaps every few hours for several days.

Outlook (Prognosis)

How well a person does depends on the amount of poison swallowed and how quickly treatment was received. Swallowing this type of poison can have severe effects on many parts of the body. The faster a person gets medical help, the better the chance for recovery.

Damage can continue to occur for several weeks after the poison was swallowed. Death may occur as long as a month after the poison was swallowed.
