Internal Use of Hydrogen Peroxide
No grade or strength of hydrogen peroxide is intended to be taken by IV or swallowed, except in the trace amounts used in the preparation of certain foods. There have been reports of serious side effects when hydrogen peroxide was taken internally by mouth, by IV, or in enemas.
Although problems are most likely when high-strength (undiluted) concentrations are used, even standard, household-strength (3%) hydrogen peroxide can cause serious side effects.
In addition, the U.S. Food and Drug Administration warns that high-strength hydrogen peroxide (such as 35% "food grade" hydrogen peroxide) is not approved by the FDA for any purpose. According to the FDA, "No one has presented any evidence that hydrogen peroxide taken internally has any medical value."
The internal use of hydrogen peroxide puts you at risk for serious side effects, including:
- Nausea and vomiting
- Stomach ulcer
- Burns in the mouth, throat, esophagus, and stomach
- Bleeding in the stomach
- Rupture of the colon
- Inflammation of the intestines.
