Poison Control, or a local emergency number

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 U.S. 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.

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

See National Poison Control center.

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. The patient may receive:

• Dialysis
• Medicines to treat symptoms
• Ethanol or fomepizole -- medicine (antidote) to reverse the effect of the poison
• A nasogastric (NG) tube thru the nose into the stomach to empty the stomach ( gastric lavage)

Expectations (prognosis)

For ethylene glycol: Death may occur within the first 24 hours. If patient survives, there may be little or no urine output for several weeks before the kidneys recover. Any brain damage may be permanent. Visual loss and or blindness may also be permanent

For methanol: Methanol is extremely toxic. As little as 2 TABLEspoons can kill a child,  while 2 to 8 oz. can be deadly for an adult. The ultimate outcome depends on how much was swallowed and how soon appropriate care was given.
