How to Prevent Cold Sores
It is not always possible to prevent an outbreak of cold sores. In people who have attacks triggered by sunburn, using sunscreen or avoiding heavy sun exposure may reduce the number of attacks. Taking daily prescription antiviral medications (see above) can significantly reduce the frequency of cold sores. However, the vast majority of people do not have enough attacks to justify taking a daily medicine.
