Poison Control

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.

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:

• Activated charcoal
• Breathing support (oxygen, possibly a breathing tube)
• Fluids through a vein (by IV)
• Laxative
• Tube through the mouth into the stomach to empty the stomach (gastric lavage)

Outlook (Prognosis)

Taking too much of this medication is not usually a problem. You may have some pain in your stomach and vomiting (possibly with blood). However, these symptoms will likely get better. Rarely, a blood transfusion may be needed.

In rare cases you may also hear ringing in your ears and have a bad headache, but these symptoms will likely pass as well.
