Hi, Thanks for writing to us. Firstly it has to be determined whether you are having herpes or not. If its herpes, then a course of oral acyclovir or valaciclovir should be started as soon as you get the erosions or fluid filled blisters. Topically to help the lesion heal fast, any antibacterial cream can be used like mupirocin or fusidic acid. Recurrence of herpes usually has some tell tale signs like itching, numbness or stinging in the area. At this stage, one can use acyclovir cream to prevent the lesions from occuring. Hope this helped Take care
