Valacyclovir 500mg

Valacyclovir 500mg — Uses and Benefits

Valacyclovir 500mg is prescribed to treat viral infections caused by herpes simplex and varicella-zoster viruses.

WHAT THIS MEDICINE IS USED FOR

• Cold sores (herpes labialis) around the mouth
• Genital herpes, including first episodes and recurrent outbreaks
• Shingles (herpes zoster) in adults
• Suppressive therapy to reduce frequency of recurrent genital herpes outbreaks
• Reducing risk of transmitting genital herpes to a partner, when used as advised by a doctor

HOW IT WORKS

• It is converted in the body to acyclovir, an antiviral substance
• It stops the herpes virus from multiplying by blocking a viral enzyme needed for copying its genetic material
• This helps reduce the severity and duration of symptoms and speeds up healing

WHAT IT IS NOT USED FOR

• It does not cure herpes infection completely; the virus remains dormant in the body
• It is not effective against bacterial, fungal infections, or common cold/flu viruses
• It does not prevent all future outbreaks or transmission in every case
• It should not be used for other viral infections unless specifically advised by a doctor
