Mercuric oxide poisoning
Mercuric oxide is a form of mercury. It is a type of mercury salt. There are different types of mercury poisonings. This article discusses poisoning from swallowing mercuric oxide.
This is for information only and not for use in the treatment or management of an actual poison exposure. If you have an exposure, you should call your local emergency number (such as 911) or a local poison control center at 1-800-222-1222.
Mercuric oxide may be found in some:
- Button batteries (batteries containing mercury are no longer sold in the United States)
There have been reports of inorganic mercury poisoning from the use of skin-lightening creams.
Note: This list may not be all inclusive.
Symptoms of mercuric oxide poisoning include:
- Abdominal pain (severe)
- Bloody diarrhea
- Decreased urine output (may stop completely)
- Extreme difficulty breathing
- Metallic taste in the mouth
- Mouth sores
- Throat swelling (swelling may cause throat to close)
Seek immediate medical help. DO NOT make a person throw up unless told to do so by Poison Control or a health care professional. If clothing is contaminated with the poison, try to safely remove it while protecting yourself from contact with the poison.
Before Calling Emergency
The following information is helpful for emergency assistance:
- Person's age, weight, and condition (for example, is the person awake or alert?)
- Name of the product (ingredients and strengths, if known)
- Time it was swallowed
- Amount swallowed
However, DO NOT delay calling for help if this information is not immediately available.
Poison Control What to Expect at the Emergency Room
In the United States, call 1-800-222-1222 to speak with a local poison control center. This hotline number will let you talk to experts in poisoning. They will give you further instructions.
This is a free and confidential service. 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.
The health care provider will measure and monitor vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. The person may receive:
- Airway support, including oxygen, breathing tube through the mouth (intubation), and breathing machine (ventilator)
- Blood and urine tests
- Camera down the throat (endoscopy) to see burns in the food pipe (esophagus) and stomach
- Chest x-ray
- EKG (electrocardiogram, or heart tracing)
- Fluids through a vein (intravenous or IV)
- Medicines to treat symptoms
- Medicines called chelators that remove mercury from the bloodstream, which may reduce long-term injury
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. It is very important to seek immediate medical help after a battery is swallowed.
How well a person does depends on the amount of poison swallowed and how quickly treatment was received. The faster a person gets medical help, the better the chance for recovery. Mercuric oxide poisoning can lead to organ failure and death.
