Can you gargle with hydrogen peroxide?

Hydrogen peroxide, also known as hydrogen peroxide solution, can be used for gargling, but care should be taken to avoid prolonged use.
Hydrogen peroxide solution is a disinfecting and antiseptic medicine, which is mainly used clinically for purulent otitis externa and otitis media, gingival abscess and leakage, Vincent’s stomatitis, tonsillitis and cleaning wounds. After the appearance of the above oral diseases, this drug can be applied to gargle, which can serve as a disinfectant and antiseptic.
Adverse effects of hydrogen peroxide solution include tingling and the formation of “white scabs” after the application of high concentrations of the solution; prolonged use as a gargle may lead to hypertrophy of the papillae of the tongue; and when used as an enema, it may lead to gas embolisms or intestinal gangrene.
The contraindications of hydrogen peroxide solution are not clear, but the drug is easy to decompose and deteriorate when exposed to light and heat, and should be stored properly. In addition, it should be used with caution in special populations such as pregnant women, nursing mothers and children.
If you need to apply hydrogen peroxide solution, it is recommended to follow the doctor’s instructions for rational application after examination and diagnosis.
