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 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.

See: Poison control center - emergency number

What to expect at the emergency room

The health care provider will measure and monitor your vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. You may receive:

• Activated charcoal
• Fluids through a vein (by IV)
• Laxative
• Tube through the nose into the stomach to wash out the stomach (gastric lavage)

Expectations (prognosis)

If the patient survives the first 24 hours, survival is likely. Few patients actually die from this type of overdose.
