Don't waste your time or money on herplex. It doesn't have in any ingredients that have been proven to be effective at treating herpes.
there aren't any studies on daily suppressive therapy with any of the 3 herpes antivirals reducing the transmission of hsv1 to a partner either orally or genitally. If you feel you still need the peace of mind - daily suppressive therapy with acyclovir would be the cheapest option though there's no guarantee's it will help at all.
