What Can The Patient Do?

If fever blisters erupt, keep them clean and dry to prevent bacterial infections. Eat a soft, bland diet to avoid irritating the sores and surrounding sensitive areas. Be careful not to much the sores and spread the virus to new sites, such as the eyes or genitals. To make sure you do not infect others, avoid kissing them or touching the sores and then touching another person.

There is good news for people whose fever blister outbreaks are triggered by sunlight. Scientists at the National Institute of Dental and Craniofacial Research have confirmed that sunscreen on the lips can prevent sun-induced recurrences of herpes. They recommend applying the sunscreen before going outside and reapplying it frequently during sun exposure. The researchers used a sunblock with a protection factor of 15 in their studies.

Little is known about how to prevent recurrences of fever blisters triggered by factors other than sunlight. People whose cold sores appear in response to stress should try to avoid stressful situations. Some investigators have suggested adding lysine to the diet or eliminating foods such as nuts, chocolate, seeds or gelatin. These measures have not, however, been proven effective in controlled studies.
