Hydrogen peroxide is a liquid commonly used to fight germs. Hydrogen peroxide poisoning occurs when large amounts of the liquid come in contact with the lungs or eyes.

Hydrogen peroxide

• Hydrogen peroxide
• Hair bleach
• Some contact lens disinfectants

Note: Household hydrogen peroxide has a 3% concentration.That means it contains 97% water and 3% hydrogen peroxide. Hair bleaches usually have a concentration of greater than 6%. Some industrial strength solutions contain more than 10% hydrogen perioxide.

• Abdominal pain and cramping
• Breathing difficulty (if large concentrations were swallowed)
• Body aches
• Burns in the mouth and throat
• Eye burns
• Seizures (rare)
• Temporary white color to the skin
• Vomiting

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 the chemical is on the skin or in the eyes, flush with lots of water for at least 15 minutes.

Determine the following information:

• Patient's age, weight, and condition
• Name of the product (ingredients and strengths, if known)
• Time it was swallowed
• Amount swallowed

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 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.

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

The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure.

Symptoms will be treated as appropriate. The patient may need a tube down the throat into the stomach (gastric tube) to relieve gas pressure.

Most contact with household strength hydrogen peroxide is relatively harmless. Inappropriate exposure to industrial strength hydrogen peroxide can be dangerous.
