Hi,
If fever blisters erupt, they should be kept clean and dry to prevent bacterial infections. Refrain from touching the sores and spreading the virus to new sites, such as the eyes and genitals. It is also important to wash hands after eating or touching the lesion. Ice applied directly to the cold sore site prior to the eruption of a blister may reduce the potential swelling. Any drying over-the-counter cold sore preparation that contains camphor and/or phenol may provide relief if applied in the early stages. When used in the scab stage, these ointments can help prevent painful cracking and bleeding.
Oral acyclovir or the recently developed drugs, valacyclovir (Valtrex) or famciclovir (Famvir), lessen the symptoms and frequency of fever blister recurrences for some patients. These drugs prevent HSV from multiplying and are effective when taken in pill form prior to an outbreak of the virus. Topical antiviral creams containing acyclovir (Zovirax) or penciclovir (Denavir) may also help in limiting the extent or duration of lesions if applied promptly to affected areas.
Take care and regards.
