Active Ingredient: Valacyclovir Hydrochloride is an acyclovir prodrug that, after metabolization, inhibits viral DNA replication. This active component is indicated in the management of herpes simplex and varicella-zoster infections, as well as prophylactically for human cytomegalovirus infections. This agent is an organic molecular entity.
Indications: Valacyclovir composed medication is indicated to treat infections caused by certain types of viruses.

It reduces how long pain remains after the sores heal.
