Poison Control, or a local emergency number

The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national 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 U.S. 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.

Take the container with you to the hospital, if possible.

See National Poison Control center.

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:

• Medicines to treat symptoms
• Breathing help
• A nasogastric (NG) tube thru the nose into the stomach to empty the stomach (gastric lavage) -- if vomiting has not occurred
• Atropine and pralidoxime, medicine (antidote) to reverse the effect of the poison
• Irrigation (washing of the skin), perhaps every few hours for several days

Expectations (prognosis)

Patients that continue to improve over the first 4 to 6 hours (after receiving medical treatment) usually recover.
