Maybe yes. The patent for Valtrex ran out quite recently, but I don't know whether generic valacyclovir is yet available. If so, it might not make much difference in price. The earliest generics often are priced only a little lower than the branded product.
Is there a generic form Valacylcovir...........thanks
Welcome to the STD forum. Lots of questions there; I can't cover all of them in the detail you might like.
The efficacy of an uninfected person taking anti-herpes therapy in preventing HSV-2 infection has never been studied and isn't known. Logically it should be protective. If both the infected and uninfected members of a couple consistently take any of the anti-HSV drugs (acyclovir, valacyclovir, famciclovir), I cannot imagine transmission taking place.
You are wrong about suppressive therapy and blood test results. If someone catches HSV-2, the blood test becomes positive. If it remains negative, no infection occurred.
For suppressive therapy to prevent transmission, I normally rely on valacylcovir 1.0 g once daily. Acyclovir probably works at a dose of 400 mg twice daily, but has not been specifically studied for prevention of transmission. Once daily (800 mg) probably is OK, but I wouldn't recommend relying on it. Time of day of single dose therapy shouldn't make any difference. All these drugs are extremely safe with no known long term side effects.
LIke you, I hope some of the newer approaches to HSV vaccines will be productive, but I am not highly optimistic. Even if I'm wrong and a good vaccine emerges, it likely will take the better part of a decade before something actually becomes available -- so don't hold your breath.
I hope that helps. Best wishes-- HHH, MD
