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.

You can also get online poison help now at Poisonhelp.org. Just enter the product, poison, or medicine to get expert help.

What to Expect at the Emergency Room

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

People who have been poisoned by diazinon will likely be treated by first responders (firefighters, paramedics) who arrive when you call 911 or your local emergency number. These responders will decontaminate the person by removing the person's clothes and washing them down with water. The responders will wear protective gear. If the person is not decontaminated before getting to the hospital, emergency room personnel will decontaminate the person and provide other treatment.

The health care providers at the hospital will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. The person may receive:

• Blood and urine tests
• Breathing support, including oxygen, tube through the mouth into the throat, and breathing machine
• Chest x-ray
• Head CT (computerized tomography) scan
• Electrocardiogram (ECG)
• Intravenous fluids (through a vein)
• Medicines to reverse the effects of the poison
• Tube placed down the nose and into the stomach (sometimes)
• Washing of the skin (irrigation) and eyes, perhaps every few hours for several days

Outlook (Prognosis)

People who continue to improve over the first 4 to 6 hours after receiving medical treatment usually recover. Prolonged treatment often is needed to reverse the poisoning. This may include staying in the hospital intensive care unit and getting long-term therapy. Some effects of the poison may last for weeks or months, or even longer.

Keep all chemicals, cleaners, and industrial products in their original containers and marked as poison, and out of the reach of children. This will reduce the risk of poisoning and overdose.
