✅ “FERAVIR 400 mg Tablets (Famciclovir) – Reliable Antiviral Treatment for Herpes & Shingles”

🔬 What is FERAVIR 400 mg?

FERAVIR 400 mg is an oral antiviral medication used for managing infections caused by the herpes virus family, particularly:

• Herpes zoster (shingles)
• Genital herpes (HSV-2)
• Cold sores (HSV-1)
• Herpes infections in immunocompromised patients

Its active ingredient, Famciclovir, is converted in the body to penciclovir, which helps stop the herpes virus from multiplying and reduces the severity and duration of symptoms.

⚙️ How It Works

Famciclovir is a prodrug that becomes penciclovir triphosphate inside virus-infected cells. This compound:

• Inhibits viral DNA polymerase
• Prevents replication of the herpes virus
• Targets only virus-infected cells, reducing damage to healthy cells
• Helps reduce viral load and speed up healing

FERAVIR 400 mg is commonly prescribed for:

• Shingles (Herpes Zoster): To reduce pain, rash severity, and healing time
