 ABOUT X-VIR Tablets

X-VIR is an antiviral that belongs to a class of drugs known as hepatitis B virus nucleoside reverse transcriptase inhibitors.

Entecavir is an antiviral medication. Entecavir prevents certain virus cells from multiplying in your body. It works by blocking the DNA synthesis in hepatitis B virus, a process essential for the virus to grow and multiply. Entecavir thus stops the virus from spreading in the body. It does not prevent spread of HBV infections to other people.


X-VIR is used to treat long-term hepatitis B infection. Hepatitis B is an infection of the liver caused by the hepatitis B virus. Long-term infection can cause liver damage, rarely liver cancer, and liver failure. Entecavir helps to decrease the amount of hepatitis B virus in your body.

Entecavir is used to treat long-term infection of the liver (hepatitis) caused by hepatitis B virus (HBV). It is also used to prevent HBV reinfection after liver transplant and to treat HIV patients infected with HBV. Entecavir can be used in individuals with damaged liver that still functions properly (compensated liver disease) and in individuals with damaged liver that does not function properly (decompensate liver disease).
