Entecavir is a powerful antiviral medicine used to treat chronic Hepatitis B virus (HBV) infection in adults and children. It works by suppressing the virus, preventing liver damage, and reducing the risk of cirrhosis and liver failure.

It is available under different brand names, including:

  • Baraclude (Original brand)
  • Ecavir
  • Centaurus

These medicines contain the same active ingredient (Entecavir) but differ in brand, manufacturer, and price.

What is Entecavir Used For?

Entecavir is used for:

  • Chronic Hepatitis B infection
  • Reducing viral load in Hepatitis B patients
  • Preventing liver damage caused by HBV
  • Managing long-term Hepatitis B treatment

Important: Entecavir does not cure Hepatitis B, but it controls the virus effectively.

How Entecavir Works

Entecavir is a nucleoside analogue that blocks the replication of Hepatitis B virus by interfering with viral DNA synthesis. This reduces the amount of virus in the blood and protects the liver from further damage.

Dosage

The dosage depends on the patient’s condition and previous treatment history:

  • Standard dose: 0.5 mg once daily
  • For resistant cases: 1 mg once daily
  • Must be taken on an empty stomach (at least 2 hours after meals)
  • Dose adjustment may be needed in kidney disease

Always follow your doctor’s prescription.
