VALADERM-1000 TAB

# VALACYCLOVIR 1000 MG ## SHORT DESCRIPTION **Valacyclovir 1000 mg** is an **antiviral medicine** used to treat infections caused by herpes viruses. It is commonly prescribed for **herpes zoster (shingles), genital herpes, and herpes labialis (cold sores)**. It may also be used to reduce recurrence and transmission of genital herpes in appropriate patients. Valacyclovir is converted in the body to **acyclovir**, which interferes with herpes virus DNA replication and helps control the infection. > **Important:** Valacyclovir does not eliminate herpes viruses from the body or permanently cure herpes infections. It helps shorten outbreaks, reduce symptoms, and suppress viral activity. --- ## KEY BENEFITS * **Helps Control Herpes Virus Infections:** Inhibits replication of herpes viruses. * **Supports Faster Outbreak Management:** Can shorten the duration of symptoms when started promptly. * **Helps Reduce Pain and Discomfort:** May reduce the severity and duration of herpes-related lesions. * **Treats Shingles:** Commonly used for herpes zoster when started early. * **Treats Genital Herpes:** Can be used for initial or recurrent genital herpes according to the prescribed regimen. * **Helps Prevent Recurrences:** Daily suppressive therapy may reduce recurrent genital herpes outbreaks. * **May Reduce Transmission:** In certain patients with recurrent genital herpes, suppressive therapy can reduce the risk of transmission when combined with safer-sex practices. --- ## USES / INDICATIONS Valacyclovir 1000 mg may be prescribed for: * **Herpes zoster (shingles)** * **Genital herpes (HSV-1 or HSV-2)** * **Herpes labialis (cold sores)** * Recurrent genital herpes * Suppression of recurrent genital herpes * Reduction of genital herpes transmission in appropriate patients * Other herpes-virus infections when specifically recommended by a healthcare professional The approved indications and dosing schedules may vary by country and patient age. --- ## HOW IT WORKS Valacyclovir is a **prodrug of acyclovir**. After oral administration, valacyclovir is rapidly converted into acyclovir. Acyclovir is activated preferentially in herpes-infected cells and inhibits the viral **DNA polymerase** enzyme. This interferes with viral DNA replication and helps stop the virus from multiplying. As a result, valacyclovir can: * Reduce viral replication * Shorten the duration of some outbreaks * Help lesions heal faster * Reduce the severity of symptoms * Reduce the frequency of recurrent outbreaks when used suppressively Valacyclovir **does not remove the herpes virus from the body**. --- ## DOSAGE & ADMINISTRATION **Take Valacyclovir 1000 mg exactly as prescribed by your doctor.** The dose and treatment duration depend on the infection being treated, age, immune status, and kidney function.
