Valaciclovir 500 mg Tablets are an antiviral medicine used to treat shingles (herpes zoster). They work by stopping the varicella-zoster virus, which causes shingles, from multiplying and spreading in the body. While valaciclovir does not cure the infection, it helps reduce the severity and duration of symptoms such as pain, rash, and blisters, and lowers the risk of complications like post-herpetic neuralgia.

Treatment is most effective when started as soon as possible after the first signs of shingles appear. Taken regularly over a short course, Valaciclovir supports faster healing and helps limit the discomfort caused by the infection.
