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 (possibly artificial respiration)
  • Fluids through a vein (by IV)
  • Laxative
  • Medication to reverse the effect of the painkiller (a narcotic antagonist)
  • Tube through the nose into the stomach to empty the stomach (gastric lavage)

Outlook (Prognosis)

Codeine is usually found in combination with other medications such as acetaminophen. Therefore outcome also depends on how well the toxicity of these other medications is treated. Shock, brain damage, and death are possible.
