Hydrogen peroxide exposure could be hazardous, particularly if you are exposed to hydrogen peroxide at industrial concentrations. Hydrogen peroxide (H2O2) is a colorless liquid with a chemical formula comparable to water (H2O). The critical distinction between the formulations is the additional oxygen molecule from which hydrogen peroxide derives its name since it contains one hydrogen for every oxygen molecule.

Moreover, because of the extra oxygen molecule, hydrogen peroxide may operate as a potent oxidizing agent. This implies that it could receive electrons from other materials. This makes it a potent disinfectant; it may oxidize the cell membrane of a microbe, resulting in the pathogen’s death and loss of structure.

Although various individuals consider hydrogen peroxide a safe general disinfectant, doctors warn that prolonged contact might cause irritation, and hydrogen peroxide exposure could induce severe gastrointestinal problems.


Among the symptoms of hydrogen peroxide exposure are:

  • Photophobia
  • Lacrimation
  • Corneal burns
  • Corrosion
  • Permanent scarring
  • Ulcers
  • Blisters
  • Severe burns
  • Irritation
  • Lethargy
  • Fever
  • Gas embolism
  • Gastric distension
  • Hematemesis
  • Vomiting
  • Abdominal pain
  • Gastrointestinal irritation
  • Pulmonary edema
  • Bronchitis


During hydrogen peroxide exposure, the physician will take and evaluate the patient’s vital signs, which include blood pressure, breathing rate, pulse, and temperature.

Tests that might be performed include:

Endoscopy: Inserting a camera up to the throat to see if there have been burns in the esophagus and stomach.

  • ECG (electrocardiogram or cardiac tracing)
  • Chest X-ray
  • Urine and blood testing


Because of its capabilities as a potent oxidizing agent, hydrogen peroxide, a versatile and easily accessible chemical, is a popular constituent in various disinfection and cleaning solutions. While it has several possible applications, it must be used only as a disinfectant and in products containing a safe level of hydrogen peroxide. An individual might also discover safer alternatives to hydrogen peroxide.

Treatment options for hydrogen peroxide exposure include:

  • Breathing assistance, such as a tube inserted via the mouth into the lungs and attached to a breathing machine called a ventilator.
  • Endoscopy – a medical process that involves putting a tube through the throat into the stomach to alleviate gas pressure.
  • Medications to address symptoms
  • Fluids injected into a vein (IV)

Home Care

Obtain medical attention right away. Don’t force the victim to vomit unless poison control or a health care practitioner instructs you. Also, make sure to remove the patient from further contamination.
