Istavel 100mg Tablet

Introduction

Istavel 100mg Tablet is an anti-viral medication primarily used for the treatment of herpes simplex infections, including genital herpes, cold sores, and herpes zoster (shingles). It contains the active ingredient Valacyclovir, which is converted into acyclovir in the body. This medication works by inhibiting the replication of the herpes virus, thereby reducing the severity and duration of outbreaks. Istavel is also used to prevent recurrent herpes infections and reduce the transmission of the virus. It is most effective when taken at the first signs of an outbreak.
