What is Entavir 0.5 mg Tablet?
Entavir 0.5 mg Tablet contains entecavir as its active ingredient. It belongs to a drug class called nucleoside analogues, which fight the hepatitis B virus. Cipla manufactures this tablet in a 0.5 mg strength. Doctors prescribe it to slow down a virus that attacks the liver. It doesn’t completely cure hepatitis B, but it keeps the virus under control over time.
What is Entavir 0.5 mg Tablet used for?
Entavir 0.5 mg Tablet treats long-term hepatitis B infection in adults. Doctors give it to people whose liver shows signs of ongoing damage from the virus.
- Chronic hepatitis B with active liver disease
- People with detectable hepatitis B virus in the blood
- Long-term liver protection when the virus keeps multiplying
Your doctor checks liver function and virus levels before deciding if this tablet suits you.
How does Entavir 0.5 mg Tablet act on the virus?
Hepatitis B copies itself by building new viral DNA inside liver cells. Entecavir looks like one of the building blocks the virus needs for this. Once the virus tries to use it, the copying process stops.
This slows down how fast the virus multiplies in the liver. With fewer new virus copies, the liver gets a chance to heal. Inflammation drops over months of treatment.
