Caviral Tablet 0.5 mg contains Entecavir, an antiviral medication used in the treatment of chronic hepatitis B virus (HBV) infection. It helps reduce viral replication, improves liver function, and lowers the risk of complications such as cirrhosis and liver cancer. Entecavir is considered a potent nucleoside analogue with strong antiviral activity and a high barrier to resistance.

Composition

• Active Ingredient: Entecavir 0.5 mg
• Dosage Form: Oral tablet

Mechanism of Action

Entecavir works by inhibiting hepatitis B virus DNA polymerase. It blocks three key steps in viral replication: priming of HBV DNA polymerase, reverse transcription of the negative strand, and synthesis of the positive DNA strand. This leads to a significant reduction in viral load and helps control chronic infection.

Indications

Caviral Tablet 0.5 mg is indicated for:

• Chronic hepatitis B infection in adults
• Patients with active viral replication and liver inflammation
• Compensated liver disease due to HBV
• Prevention of disease progression to cirrhosis or hepatocellular carcinoma

Dosage and Administration

• Should be taken exactly as prescribed by a physician
• Commonly taken once daily on an empty stomach (at least 2 hours after or before meals)
• Dose may vary depending on previous antiviral treatment history and liver function
• Long-term therapy is often required for sustained viral suppression

Precautions

• Not a cure for hepatitis B; only controls viral replication
• Regular monitoring of liver function and HBV DNA levels is required
• Use with caution in patients with kidney impairment (dose adjustment may be needed)
• Do not discontinue abruptly without medical advice (risk of hepatitis flare)
• Use during pregnancy only if clearly needed under medical supervision

Side Effects

Common side effects include:
