Posted:If it's a true cold sore, then it's caused by a Herpesvirus (HSV-1).
There is a great over-the-counter remedy sold in the US called ABREVA. It's a cream that prevents the virus from entering and infecting new cells. It reduces healing time by a few days and works best if applied during the prodrome.
Tablets such as acyclovir and valacyclovir (VALTREX) or topical creams such as pencyclovir (DENAVIR) also work well.
For home remedies, the treatment is symptomatic. It treats the symptom, but not the underlying cause (the virus). This consists of making sure that the area is well-lubricated and obstructed with a thick barrier such as a soothing ointment.
Be sure not to kiss anyone during a cold sore outbreak as this can spread the infection, although over 90% of adult Americans are infected, whether they get cold sores or not.
