VALTREX (valacyclovir hydrochloride) is the hydrochloride salt of the L-valyl ester of the antiviral drug acyclovir.
Valacyclovir inhibits the replication of viral DNA which is necessary for viruses to reproduce themselves. Valacyclovir is actually a "prodrug," in that it is not active itself. Rather, it is converted to acyclovir (Zovirax)in the body, and it is the acyclovir that is active against the viruses.
