If I am on a daily dose of Valtrex (1 gram) using it as a suppressant for HSV 2, is it okay to double up and take 1 gram twice daily for a 3 days, when I get an outbreak? Then go back to the 1 gram daily after that... I have been on the daily dose for about 2 months now.. Yes I still get outbreaks.. I don't know why? I also take daily vitamins of echinacea, St. John's wort, and vitamins A, D, and E.
