I was recently diagnosed with herpes, (apparently I'm one of the people who have had it for a long time and did not know it) and was given Valtrex to take to help with the outbreak. I have finished this and am now ready to start suppressive medication daily. My gyn has suggested taking 500mg of valtrex daily and my family docotor suggested taking 200mg daily of Acyclovir. From some of what I have read the Acyclovir dose she is suggesting isn't the standard and I have also read you can build a tolerance to it. Any help would be greatly appreciated
