Mercuric oxide

Overview Symptoms Treatment
Home Treatment:

If there has been an ingestion of a button battery, DO NOT INDUCE VOMITING. The person who ingested the battery will need immediate X-rays at a medical facility to make sure the battery is not lodged in the esophagus.

Most swallowed batteries that pass through the esophagus will then pass in the stool without complication. However, batteries lodged in the esophagus can cause esophageal erosion and can cause a hole in the esophagus very quickly, so you must obtain a medical evaluation immediately after the battery is swallowed.

Before Calling Emergency:

Determine the following:

  • the patient's age, weight, and condition
  • the name of the product (ingredients and strengths if known)
  • the time it was swallowed
  • the amount swallowed
Poison Control, or a local emergency number:

See Poison Control centers for telephone numbers and addresses. Take the container with you to the emergency room.

If a button battery was ingested, you can call the 24-hour National Button Battery Ingestion Hotline at (202) 625-3333.

What to expect at the emergency room:

Some or all of the following procedures may be performed:

  • The use gastric lavage
  • Upper GI endoscopy to retrieve a battery lodged in the esophagus
  • Administration of activated charcoal
  • Administration of a cathartic (a medication used to evacuate the bowels)
  • Administration of an antidote
Expectations (prognosis):
Prognosis depends upon the amount and route of exposure. Outcome from mercuric oxide overdose can range from complete recovery to irreversible organ damage or even death
