I believe that I was exposed to HSV2 about 8 days ago. I had flu-like symptoms for 5-6 days, but have not developed any sores, yet. However, I do have three small painless whitish 'bumps' on my penis. If I started taking Valtrex now, would that minimize my chances for a bad first outbreak? If so, should I be taking 1000 mg 2x a day or just once? Thanks!
