Valovir 500 mg is an antiviral medication that contains the active ingredient Valacyclovir Hydrochloride, equivalent to 500 mg of valacyclovir per tablet. It is used primarily to treat infections caused by certain types of viruses, including herpes simplex (such as cold sores and genital herpes), herpes zoster (shingles), and varicella (chickenpox) in certain cases. Valacyclovir works by slowing the growth and spread of the virus in the body, helping to reduce the severity and duration of outbreaks, while promoting faster healing of sores. It is typically prescribed by healthcare providers for both treatment and suppression of recurrent outbreaks. Valovir is usually taken orally, with or without food, and dosage may vary based on the condition being treated, patient age, and kidney function.
