I'm interested in better understanding transmission reduction through the use of antiviral medication like valacyclovir etc. I carry HSV1g and Ive been told that if these antivirals are taken daily then it greatly reduces the chance for transmission and possibly shedding. I want to know if the medication sis as effective if taken in periods, like every day starting few days before planned sex or does it need to be taken 7 days a week 365 days a year to remain effective?
