- Amount swallowed

T Poison Control
P 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 national hotline number will let you talk to experts in poisoning. They will give you further instructions.
P 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.

T What to Expect at the Emergency Room
P Take the container with you to the hospital, if possible.
P The provider will measure and monitor the person’s vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated.
P The person may receive:
- Activated charcoal
- Breathing support, including tube through the mouth into the lungs, and breathing machine (ventilator)
- Bronchoscopy: camera down the throat to see burns in the airways and lungs
- Chest x-ray
- EKG (electrocardiogram or heart tracing)
- Endoscopy: camera down the throat to see burns in the esophagus and the stomach
- Fluids through a vein (IV)
- Medicine called an antidote to reverse the effect of the poison
- Tube through the mouth into the stomach to wash out the stomach (gastric lavage)
- Surgery to remove burned skin
- Washing of the skin (irrigation), perhaps every few hours for several days

T Outlook (Prognosis)
P How well someone does depends on how severe their poisoning is and how quickly they receive treatment. The faster medical help is given, the better the chance for recovery. Damage can continue to occur for several weeks after swallowing glaze. Permanent brain damage may occur.
