Valtrex 1000 mg Tablets contain Valacyclovir, an antiviral medication used for treating and suppressing infections caused by herpes viruses, including herpes zoster (shingles), genital herpes, and cold sores. Valacyclovir is a prodrug of acyclovir and offers improved bioavailability, making it effective with less frequent dosing.
