Seek medical help right away. DO NOT make a person throw up unless told to do so by poison control or a health care professional.

Before Calling Emergency

The following information is helpful for emergency assistance:

• The person's age, weight, and condition
• The name of the product (ingredients and strengths if known)
• The time it was swallowed
• The amount swallowed
• If the medicine was prescribed for the person

However, DO NOT delay calling for help if this information is not immediately available.

Poison Control

Your local poison control center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. This 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 person's vital signs, including temperature, pulse, breathing rate, and blood pressure.

Symptoms will be treated as appropriate.

The person may receive:

• Activated charcoal
• Airway support, including oxygen, breathing tube through the mouth (intubation),and ventilator (breathing machine)
• Blood and urine tests
• Chest x-ray
• Computerized axial tomography (CT, or advanced imaging) scan
• ECG (electrocardiogram, or heart tracing)
• Fluids through the vein (intravenous or IV)
• Laxative
• Medicines to treat symptoms, including naloxone, an antidote to reverse the effects of the poison; many doses may be needed

Outlook (Prognosis)

How well the person does depends on the severity of the overdose and how quickly treatment is received. If the proper narcotic antagonist (drug to counteract the effects of narcotics) can be given, recovery from an acute overdose occurs within 24 to 48 hours. However, if there has been prolonged coma and shock (damage to multiple internal organs), a more serious outcome is possible.
