Hydrogen peroxide is a liquid commonly used to fight germs. Hydrogen peroxide poisoning occurs when large amounts of the liquid are swallowed or get in the lungs or eyes.
This article is for information only. DO NOT use it to treat or manage an actual poison exposure. If you or someone you are with has an exposure, call your local emergency number (such as 911), or your local poison center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States.
Hydrogen peroxide can be poisonous if it is not used correctly.
Hydrogen peroxide is used in these products:
- Hydrogen peroxide
- Hair bleach
- Some contact lens cleaners
Note: Household hydrogen peroxide has a 3% concentration. That means it contains 97% water and 3% hydrogen peroxide. Hair bleaches are stronger. They usually have a concentration of more than 6%. Some industrial-strength solutions contain more than 10% hydrogen peroxide.
Hair bleach poisoning occurs when someone swallows hair bleach or splashes it on their skin or in their eyes. This article is for information only. ...Read Article Now Book Mark Article
Symptoms of a hydrogen peroxide poisoning include:
- Abdominal pain and cramping
- Breathing difficulty (if a large amount is swallowed)
- Body aches
- Burns in the mouth and throat (if swallowed)
- Chest pain
- Eye burns (if it gets in the eyes)
- Seizures (rare)
- Stomach swelling
- Temporary white color to the skin
- Vomiting (sometimes with blood)
Seek medical help right away. Do NOT make the person throw up unless poison control or a health care provider tells you to do so. If the chemical is on the skin or in the eyes, flush with lots of water for at least 15 minutes.

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 done include:
- Blood and urine tests
- Chest x-ray
- ECG (electrocardiogram or heart tracing)
- Endoscopy -- camera placed down the throat to check for burns in the esophagus and stomach
Treatment may include:
- Fluids through a vein (by IV)
- Medicines to treat symptoms
- Tube down the throat into the stomach (endoscopy) to relieve gas pressure
- Breathing support, including a tube through the mouth into the lungs and connected to a breathing machine (ventilator)
Most contact with household-strength hydrogen peroxide is fairly harmless. Exposure to industrial-strength hydrogen peroxide can be dangerous. Endoscopy may be required to stop internal bleeding.
