Entecavir

Uses

Entecavir is used in the treatment of chronic hepatitis B virus (HBV) infection.

How it Works

How Entecavir works: Entecavir is an antiviral medication that inhibits the replication of the virus in human cells. This action prevents the virus from producing new viral particles and helps to resolve the infection.

Side Effects

Common side effects of Entecavir include increased alanine aminotransferase levels.

Frequently asked questions

Entecavir should be taken exactly as prescribed by your doctor, usually once daily on an empty stomach, at least 2 hours after a meal and 2 hours before the next meal. Aim to take it at the same time each day. Consult your doctor if you have any questions.
No, Entecavir does not cure hepatitis B but may improve liver condition by reducing the amount of hepatitis B virus (HBV) in the body, limiting its ability to replicate and infect new liver cells.
Do not discontinue Entecavir without consulting your doctor, as stopping treatment prematurely may worsen your hepatitis, especially in the first few months after cessation. Adhere strictly to the prescribed dosage.
Yes, Entecavir can lead to serious liver issues such as hepatomegaly (enlargement of the liver) and steatosis (fat buildup in the liver). This combination is a medical emergency requiring immediate attention.
Symptoms of liver problems include jaundice (yellowing of the skin or eyes), dark urine, light-colored stools, loss of appetite, nausea, and stomach pain. These symptoms are more prevalent in women, overweight individuals, or those on Entecavir for extended periods. Contact your doctor immediately if you experience any of these symptoms.
Drug resistance occurs when a medication that was once effective becomes ineffective due to changes in the virus or bacteria. With Entecavir, resistance is more likely if you take a lower dose than recommended.
Entecavir is not recommended for HBV patients with co-existing HIV unless they are receiving HIV treatment. Starting Entecavir in these patients may lead to resistance against HIV medications. Testing for HIV is advised before initiating Entecavir treatment.
