If she did get HSV 2 orally, she could definitely take Valtrex to reduce the symptoms and shorten the duration of her outbreak. The dose
to treat recurrent cold sores is 2 grams of
Valtrex, then 12 hours later, another 2 grams. But that's recurrent disease, not first episode oral infection. We have no studies on that, but if it was my patient that acquired first episode HSV 2 orally, I would treat with the genital herpes first episode dosing - 1 gram twice a day for 10 days.
