Entavir 1.0 mg

Introduction to Entavir 1 mg Tablets

Entavir 1 mg Tablet, containing the active ingredient entecavir, is a medication primarily used to treat chronic hepatitis B virus (HBV) infection. Hepatitis B is a serious viral infection that affects the liver, leading to inflammation, liver damage, and potentially life-threatening complications such as cirrhosis and liver cancer if left untreated.

Entavir 1 mg Tablet is not a cure for HIV or AIDS and only helps to decrease the amount of HIV in your body. This helps to lower your risk of getting HIV-related complications and improves your lifespan. It is prescribed in combination with other HIV medicines. Your doctor will recommend the best medicines for you and will decide the doses that you need.

The medication is typically prescribed as a long-term therapy, taken orally once daily. It is well absorbed from the gastrointestinal tract and converted into its active form in the body. Tenofovir competes with natural substrates to integrate into viral DNA, effectively disrupting the replication process and preventing the virus from spreading.

How does Entavir 1 Work?

Entavir 1 mg Tablet contains the active ingredient entecavir, an antiviral medication that prevents the virus from multiplying in human cells. This stops the virus from producing new viruses & clears up your infection.

Entecavir is a nucleoside analogue, specifically a deoxyguanosine analogue belonging to the class of carbocyclic nucleosides. It inhibits reverse transcription and DNA replication during the viral replication process.

Other nucleoside and nucleotide analogues include telbivudine, lamivudine, adefovir dipivoxil, and tenofovir. Entecavir decreases the amount of HBV in the blood by reducing its ability to multiply and infect new cells.

Warnings & Precautions

1. Liver Disease:

• Entecavir should be used with caution in patients with liver conditions like cirrhosis. It may worsen liver disease, especially if treatment is stopped abruptly. Regular monitoring of liver function is recommended.

2. HIV Co-infection:

• Entecavir is not effective against HIV and may not be suitable for individuals co-infected with both hepatitis B and HIV. It’s important to manage both infections carefully to avoid resistance development.

3. Discontinuation of Treatment:

• Stopping Entecavir suddenly can lead to a flare-up of hepatitis B, potentially causing severe liver damage. Do not stop the medication without consulting your healthcare provider.

4. Lactic Acidosis:

• Lactic acidosis (buildup of lactic acid in the blood) is a rare but serious side effect. Symptoms may include nausea, vomiting, unusual tiredness, and muscle pain. Immediate medical attention is required if any of these symptoms occur.

5. Kidney Function:

• Entecavir is primarily cleared through the kidneys, so it may accumulate in patients with kidney problems. Dose adjustments may be necessary in those with impaired renal function, and kidney function should be monitored regularly.

6. Pregnancy and Breastfeeding:

• Entecavir should only be used during pregnancy if the benefits outweigh the risks. Consult with a doctor before using Entecavir if you are pregnant or planning to become pregnant. It is not known whether Entecavir is excreted in breast milk, so it should be used with caution in breastfeeding mothers.

7. Resistance:

• Improper use of Entecavir may lead to resistance. Adhere to the prescribed dosage and treatment plan to reduce the risk of resistance.

8. Allergic Reactions:

• In rare cases, severe allergic reactions can occur, with symptoms like rash, itching, swelling, or difficulty breathing. Seek immediate medical attention if any of these symptoms develop.

Storage
