Valcivir 500mg

Valcivir 500mg is an antiviral medication containing valacyclovir, used primarily to treat herpes simplex infections, shingles, and chickenpox. It works by inhibiting viral replication, reducing outbreak severity, and accelerating healing.

Physicians often prescribe it for cold sores and genital herpes, helping to minimize transmission risks. Valcivir is rapidly converted into acyclovir in the body, enhancing its bioavailability. Patients should take it as directed, with or without food, and stay hydrated.

Common side effects include nausea, headache, or dizziness. In rare cases, it may cause kidney issues or neurological effects.

How Valcivir 500mg Works ?

Valcivir 500mg contains valacyclovir, which is a prodrug of acyclovir. Once ingested, the body converts valacyclovir into acyclovir, which then targets virus-infected cells.

• Inhibits Viral DNA Replication – Acyclovir blocks the action of the viral enzyme DNA polymerase, preventing the virus from multiplying.
• Reduces Viral Load – Slows the spread of the virus, reducing outbreak severity and duration.
• Speeds Up Healing – Helps lesions heal faster and decreases pain, especially in shingles and herpes infections.
• Prevents Recurrences – Regular use can suppress future outbreaks and lower transmission risks.

 Dosage

• Genital Herpes: First outbreak – 1000mg twice daily for 10 days; recurrent – 500mg twice daily for 3 days; suppression – 500–1000mg daily.
