Poison Control, or a local emergency number
In the United States, call 1-800-222-1222 to speak with a local poison control center. This hotline number will let you talk to experts in poisoning. They will give you further instructions.
This is a free and confidential service. 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.
Take the container with you to the hospital, if possible.

What to expect at the emergency room
Treatment depends on how the poisoning occurred. The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. Pain medicines will be given.
For swallowed poison, the patient may receive:
- Endoscopy -- camera down the throat to see burns in the esophagus and the stomach
- Fluids by IV
For inhaled poisons, the patient may receive:
- Breathing support, possibly a breathing tube
- Bronchoscopy -- camera down the throat to see burns in the airways and lungs
For skin exposure, the patient may receive:
- Skin debridement (surgical removal of burned skin)
- Washing of the skin (irrigation) -- perhaps every few hours for several days
How well a patient does depends on the amount of poison swallowed and how quickly treatment was received. The faster a patient gets medical help, the better the chance for recovery.
Extensive damage to the mouth, throat, eyes, lungs, esophagus, nose, and stomach are possible. The ultimate outcome depends on the extent of this damage. Damage continues to occur to the esophagus and stomach for several weeks after the poison was swallowed, and death may occur as long as a month later.
