Got an ob yesterday took my Valtrex as prescribed, then campho-phenique on and off all day, along with rubbing alcohol ,last night I tried the toothpaste method ( Colgate not gel pure white) overnight and it did dry it out more still taking my meds as prescribed but my ob is all dried out. On to the next phase of dealing with it with neosporen just a little bit not to moisten it too much. Hope this helps....
