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.

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

See: Poison control center - emergency number

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. Symptoms will be treated as appropriate. The patient may receive:

• Breathing support
• Fluids by IV
• Activated charcoal
• Medicine (antidote) to reverse the effect of the poison
• Tube through the mouth into the stomach to empty the stomach (gastric lavage)

Expectations (prognosis)

If the patient survives the first 24 hours, recovery is good. Few patients die from an antihistamine overdose.
