Use docosonal.: Abreva (Docosonal) is an FDA approved over the counter topical remedy used to help speed healing and minimize pain from a cold sore (shortens ~ 3 d). The drug prevents the cold sore virus (herpes) from getting into healthy cells so the viral particles can’t spread to new cells . Camphor, menthol, phenol, and ice may sooth the area.
