Before Calling Emergency

Have this information ready:

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 national hotline 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

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

The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure.

Tests that may be done include:

Treatment may include:

Outlook (Prognosis)

Isopropanol and methanol are extremely poisonous. As little as 2 tablespoons (14.8 milliliters) of methanol can kill a child, while 2 to 8 ounces (59 to 236 mL) can be deadly for adults.

How well a person does depends on the amount of poison swallowed and how quickly treatment was received. The faster medical help is given, the better the chance for recovery.

Swallowing such poisons can have severe effects on many parts of the body. Burns in the airway or gastrointestinal tract can lead to tissue necrosis, resulting in infection, shock and death, even several months after the substance was first swallowed. Scars may form in these tissues leading to long-term difficulties with breathing, swallowing, and digestion.
