2.65% Hydrogen Peroxide: Uses, Side Effects, and Drug Interactions

# Hydrogen Peroxide 2.65% Overview Hydrogen peroxide at 2.65% strength is a common antiseptic used to clean minor cuts, scrapes, and wounds. It works by killing bacteria and helping to remove dead skin and other debris from injured areas. When you apply it to a wound, you'll notice it foams up—this fizzing action is actually part of how it cleans the wound. Many people keep this product in their medicine cabinet for basic first aid care at home. When using this product, it's important to follow safety rules to protect yourself and others. Never swallow hydrogen peroxide or get it in your eyes, and keep it away from children and pets who might accidentally drink or misuse it. Use the product only on the skin's surface and stop using it if your skin becomes irritated or the wound doesn't improve. Always read the label carefully before using, and if you have questions about whether this product is right for your situation, talk to a pharmacist or doctor.
