The Best Antiseptic for Open Wounds First Aid

For moderately severe open wounds, the safest and most effective over-the-counter (OTC) antiseptics include iodine, biguanides, and peroxides.

Antiseptics are chemical solutions applied topically to the skin or wounds to reduce the growth of harmful bacteria, viruses, or fungi.

Common OTC antiseptic types include:

You can typically take care of mild wounds with antibacterial soap and water, while more severe wounds may require medical attention. Here’s what to know about antiseptic use and its safety.

The Food and Drug Administration (FDA) considers some antiseptics to be safe to use on open wounds, while it considers ingredients in other OTC options to be potentially unsafe.

The FDA has listed 24 potentially harmful antiseptic ingredients to know about. However, only one is still an active ingredient marketed as a healthcare antiseptic today. At this time, the FDA considers triclosan to be potentially unsafe to use.

Although scientists haven’t explicitly proven these ingredients to cause harm, there’s limited evidence to back their use, and their long-term effects remain unknown.

With repeated use, even antiseptics considered safe, such as isopropyl alcohol, may cause cytotoxicity in the wound, meaning they can erode healthy cells and actually slow healing, 2022 research shows. Due to their potency, experts only recommend antiseptics for use when necessary or when there’s a legitimate risk of infection.

Keep in mind that milder cuts and scrapes won’t require any antiseptic to heal — antibacterial soap will be sufficient to disinfect the area.

If your cut is larger or more serious, it’s much safer to seek medical care — more on that below.

You shouldn’t use antiseptics for deeper or more serious wounds, including:

If your wound doesn’t seem to be healing with regular antiseptic treatment and care, it’s advisable to visit a doctor as soon as possible.

Antiseptics like alcohol can be used in a pinch but can be too harsh and may actually delay healing long term.

Mild wounds typically don’t require antiseptic use, and you can safely disinfect them with soap and water. More severe wounds, such as those deeper than a quarter-inch, require support from a medical professional.

If your wound appears infected or isn’t healing, visit a doctor, clinic, or other healthcare professional.
