Valacyclovir (Valtrex, marketed by Glaxo Smith Kline) and acyclovir (Zovirax, marketed by Sanofi-Aventis) are used mainly for treatment of genital herpes.

The valacyclovir vs acyclovir debate started since then and it still remains a matter of research interest as to which drug you can use to cope with herpes better.

Clinical trials have shown that this drug has greater effectiveness in dealing with the herpes simplex virus (HSV) or the varicella zoster virus (VZV), compared to acyclovir or other drugs. Another plus factor of Valtrex is that it is probably the only medicine that can reduce the risk of herpes transmission, given that safe sex methods are used.
