Medicine Description valtrex 500 mg
Valtrex 500 mg 42 tablets is a medication that functions as a prodrug of acyclovir, which means it is converted into acyclovir in the body. Once activated, acyclovir selectively inhibits the viral DNA polymerase, an essential enzyme for viral replication. By interfering with the synthesis of viral DNA, Valtrex effectively reduces the viral load, thereby limiting the spread of infections caused by herpes viruses. This mechanism not only alleviates the initial symptoms but also contributes to lessening the frequency and severity of recurrent outbreaks.
