Does Hydrogen Peroxide Help Reduce Cold Sores?

Hydrogen peroxide is widely recognized for its disinfectant and antiseptic properties, but its effectiveness in treating cold sores caused by the herpes simplex virus (HSV) is limited.

Use of Hydrogen Peroxide for Cold Sores

Hydrogen peroxide can be used as a cleansing antiseptic to prevent infection and promote healing of cold sores. To use, simply mix a small amount of hydrogen peroxide with an equal amount of water. This can be applied to cold sores on the face using a clean cotton swab. Oral antiviral medications have been proven to be the most effective treatment for cold sores, reducing pain and helping the sore clear faster. These medications should be prescribed by a healthcare professional.

Benefits and Limitations

While hydrogen peroxide can help clean the area and reduce the risk of secondary bacterial infections, it does not directly treat the viral infection or speed up healing. It is important to note that the solution may cause bubbling, pain, or tingling, and should not be applied too vigorously to avoid dislodging a scab. It is recommended to use hydrogen peroxide during the blister phase up until the early scab phase. Applying peroxide to a soft, still wet scab can prolong the existence of the sore.

Using hydrogen peroxide is not a prevention method for new blisters or a way to make an individual less contagious. It is crucial to consult a healthcare professional before using hydrogen peroxide on cold sores, as other methods of home treatment may be more effective or preferred, such as applying ice packs or mixing baking soda or salt with water to form a paste.
