What to do if you accidentally swallow hydrogen peroxide?

Answer 1

Ingestion of small amount of the common 3% hydrogen peroxide may cause mild mucosal irritation and vomiting. If conscious drink 4 to 8 ounces of milk or water(see related link).
Its not mentioned officially but vitamin c maybe useful in reducing hydrogen peroxide and its byproducts to less harmful products.

Answer 2

It depends on how much you have swallowed and what the concentration of the hydrogen peroxide was (the percentage should be printed on the label or bottle).

For 3% concentrations, a capful won't bother you but more than a few tablespoons may irritate your mouth and throat and cause abdominal pain, vomiting, and diarrhea.

If the concentration is higher than 3% or you have swallowed a lot, you should see a doctor.

Answer 3

----

INGESTION: Rinse mouth with water. Dilute by giving 1 or 2 glasses of water. Do not induce vomiting. Never give anything by mouth to an unconscious person. See a medical doctor immediately.

---- EYES: Immediately flush with water for at least 15 minutes, lifting the upper and lower eyelids intermittently. See a medical doctor or ophthalmologist immediately.

---- SKIN: Wash with plenty of soap and water. Get medical attention if irritation occurs and persists.

---- INHALATION: Remove to fresh air. If breathing difficulty or discomfort occurs and persists, contact a medical doctor.

---- ---- Hydrogen peroxide at these concentrations is a strong

oxidant. Direct contact with the eye is likely to cause corneal damage especially if not washed immediately.

Careful ophthalmologic evaluation is recommended and the possibility of local corticosteroid therapy

should be considered. Because of the likelihood of corrosive effects on the gastrointestinal tract after

ingestion, and the unlikelihood of systemic effects, attempts at evacuating the stomach via emesis induction

or gastric lavage should be avoided. There is a remote possibility, however, that a nasogastric or orogastric

tube may be required for the reduction of severe distension due to gas formation.

Answer 4

Hydrogen peroxide decomposes and releases oxygen gas within the stomach. Lots of oxygen. About ten times as much as the volume of hydrogen peroxide swallowed (for a 3% solution, which is a pretty typical concentration sold for household use). This can cause severe distension of and damage to the stomach if a lot is swallowed. Also, hydrogen peroxide sold for external use may contain stabilizers which are toxic when taken orally, and the hydrogen peroxide itself may cause some damage to the tongue, mouth, and throat. That said, a drop or two is probably not great cause for alarm.

Answer 5

Probably die. If it was more than a tiny amount, call the poison control center. If it was a significant (like, a mouthful or more) call an ambulance directly.

An ounce of 3% hydrogen peroxide (the kind you buy at the drugstore) will liberate over a pint of oxygen in an acid environment like the inside of your stomach. That's probably not enough to cause your stomach to rupture. Probably. Do you feel lucky, punk?

And that's hoping you didn't manage to get your hands on the industrial strength stuff. An ounce of 30% hydrogen peroxide and you're looking at well over a gallon of oxygen, and this is completely ignoring the fact that it will burn your tongue and throat going down.

Answer 6

If you accidentally swallow hydrogen peroxide, do not induce vomiting. Instead, drink a small amount of water or milk to dilute the peroxide and seek medical help immediately by calling poison control or going to the nearest emergency room. It is important to get professional medical advice in case of ingestion.

Answer 7

It is very dangerous because hydrogen peroxide is corrosive and destroy the skin.

Answer 8

Called Poison Control is best. All of these answers told my daughter to drink water or milk. This is incorrect-- for Peroxide. My daughter drunk water thinking that is was best and it caused to vomit per poison control
