More Info on Hydrogen Peroxide

Is It Effective?

There is very little real scientific evidence to suggest that this substance works for most uses, even for wound cleansing.

Available Strengths

The typical hydrogen peroxide solution available to the general public in pharmacies and other retail stores is a dilute solution (3%). Hydrogen peroxide mouthwash products usually have an even lower concentration (1.5%). Higher strengths are available, but are not intended for human use or consumption.
Most notably, "food grade" strengths of this substance (typically available in a 35% strength) are not meant to be taken internally, which the name implies (see Food Grade Hydrogen Peroxide for more information).

Side Effects of Hydrogen Peroxide

The side effects of this substance can range from rather mild (for normal skin use of dilute solutions) to quite dramatic and dangerous (for excessive use or for use of concentrated solutions). If not diluted properly, highly concentrated hydrogen peroxide can be extremely toxic and potentially lethal.

Is It Safe?

When used for wound cleansing at a low concentration, hydrogen peroxide is probably safe in many situations. However, taking stronger concentrations, or taking it by mouth or by IV, is more likely to result in significant problems. Therefore, you should talk with your healthcare provider prior to taking hydrogen peroxide:
  • By mouth, IV, or enema
  • In any strength higher than 3%
  • In a deep wound, puncture wound, or serious burn.
