Entavir Tablet 0.5 mg contains Entecavir, a potent antiviral agent used for the treatment of chronic hepatitis B virus (HBV) infection in adults. Entecavir belongs to the class of nucleoside analogue reverse transcriptase inhibitors (NRTIs). It works by inhibiting the HBV DNA polymerase, thereby blocking viral replication and reducing the viral load in the liver.

Entavir 0.5 mg is typically prescribed for adult patients with chronic HBV infection who have evidence of active viral replication and liver inflammation. By suppressing viral replication, it helps prevent progression to cirrhosis, liver failure, or hepatocellular carcinoma, thereby protecting long-term liver health.

Indications

Entavir Tablet 0.5 mg is indicated for:

• Chronic hepatitis B (CHB) infection in adults with active viral replication and elevated liver enzymes

• Nucleoside-naïve patients requiring first-line therapy for chronic HBV infection

• Prevention of disease progression, including cirrhosis, liver failure, or hepatocellular carcinoma

• Long-term viral suppression to maintain liver function and reduce complications

• Alternative therapy for patients with previous lamivudine resistance, under medical supervision

This formulation is particularly useful for patients who require moderate antiviral therapy or for long-term maintenance of viral suppression.

Dosage and Administration

• Adults: One 0.5 mg tablet orally once daily, preferably on an empty stomach (at least 2 hours before or after food)

• Swallow the tablet whole with water; do not crush, chew, or split

• Treatment is generally long-term, as stopping therapy abruptly may cause viral rebound and liver flare

• Regular monitoring of HBV DNA levels, liver function tests, and kidney function is recommended to ensure safety and efficacy

• Dose adjustment may be necessary for patients with renal impairment

Precautions

• Not recommended for patients with known hypersensitivity to Entecavir or its components

• Caution in patients with severe kidney disease, as dose adjustments may be required

• Monitor for rare but serious complications such as lactic acidosis and severe hepatomegaly with steatosis

• Avoid abrupt discontinuation to prevent flare-ups of hepatitis B

• Patients should inform their doctor of all medications being taken to avoid potential interactions, especially with other antivirals or nephrotoxic drugs

• Pregnant and breastfeeding women should consult a healthcare professional before using this medication
