Know the basics

What is hydrogen peroxide used for?

Hydrogen peroxide is a mild antiseptic used on the skin to prevent infection of minor cuts, scrapes, and burns. It may also be used as a mouth rinse to help remove mucus or to relieve minor mouth irritation (e.g., due to canker/cold sores, gingivitis). Hydrogen peroxide works by releasing oxygen when it is applied to the affected area. The release of oxygen causes foaming, which helps to remove dead skin and clean the area.

This product should not be used to treat deep wounds, animal bites, or serious burns.

How should I take hydrogen peroxide?

Do not use in the eyes or apply over large areas of skin.

If you are using hydrogen peroxide on the skin, clean the affected area before use. Apply a small amount of product on the affected area, usually 1 to 3 times daily or as directed by your doctor. If you apply a bandage after using this product, let the area dry first.

If you are using this product as a mouth rinse, mix with an equal amount of water before using. Swish in the mouth over the affected area for at least 1 minute, then spit out. Do not swallow hydrogen peroxide. Rinse up to 4 times daily or as directed by your dentist or doctor.

Use hydrogen peroxide regularly in order to get the most benefit from it. To help you remember, use it at the same time(s) each day.

Tell your doctor if your condition does not improve in 7 days or if it worsens. If you think you may have a serious medical problem, seek immediate medical attention.
