Seek immediate medical help. DO NOT make a person throw up unless told to do so by Poison Control or a health care professional.

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
The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. The patient may receive:
- Blood tests to check for problems and degree of poisoning, including calcium level
- Breathing support
- Endoscopy -- camera down the throat to see burns in the esophagus (food pipe) and the stomach
- Medicines to treat symptoms
Outlook (Prognosis)
How well a patient does depends on the amount of poison swallowed, how concentrated the poison is and how quickly treatment was received. The faster a patient gets medical help, the better the chance for recovery. Severe damage to the mouth, gastrointestinal tract, or airway may occur and quickly cause death if not treated.
