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 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.

Any person who swallowed a battery will need immediate x-rays to make sure the battery is not stuck in the esophagus. Most swallowed batteries that pass through the esophagus will pass out of the body in the stool without complication. However, batteries stuck in the esophagus can cause a hole in the esophagus very quickly, leading to serious infection and shock, which may be fatal. It is very important to seek immediate medical help after a battery is swallowed.

Outlook (Prognosis)

This substance is very poisonous. How well a person does depends on the amount of poison swallowed, what symptoms occur within the first 10 to 15 minutes after swallowing it, and how quickly treatment was received. The faster a person gets medical help, the better the chance for recovery. Kidney dialysis (filtration) through a machine may be needed if the kidneys do not recover after acute mercury poisoning. Kidney failure and death can occur, even from small doses.

If the poisoning has occurred slowly over time, any brain damage may be permanent.

Mercuric oxide poisoning can lead to multiple organ failure and death.
