Diagnosed with HSV2 via blood test.  Had only one small first outbreak, extremely few minor outbreaks since, Valtrex was effective.  (A)  If I'm not having an outbreak and using a condom, what is transmission risk to my girlfriend, and how much does that risk increase if I don't use condom?  If you'll permit, (B) can Valtrex be used as a sort of pharmacological prophylactic and, if so, how much does that lower risk, and how should it be taken - right before sex or daily?  Lastly, (C) is it safe to take Valtrex frequently to prevent HSV2 transmission?  Thanks.      

Condoms used with every intercourse reduce the risk of transmission of HSV 2 by 96% and Valtrex reduces the risk of transmission when taken daily, 500 mg, by 48%.  it is completely safe to take Valtrex daily for this purpose, yes---
